Excel to PDF lets you choose how a short date is written: day/month/year (the default), month/day/year or year-month-day. Only Excel's own short-date format changes; custom formats and the values in the cells stay as they are.
Convert Audio checks a normalised MP3 before offering it: the page decodes it, makes it again under another gain if its peak is not between -2 and -1 dBFS, and states the peak the file really has. Convert Audio, Trim Audio and Join Audio say which bit depth they keep by default and why (24-bit when the file's header says 24 bits or more, otherwise 16-bit), say when a file is silent, and explain the MP3 encoder's short delay at the start, which is not silence.
From the nightly checks of the live pages: Clean Office metadata says when a file cleaned again has nothing left to remove; Resume Builder says what an opened file's fields left out or shortened, and its preview works offline; vCard Maker names each download and its size; Create ZIP never calls a ZIP 100% smaller; Extract ZIP and QR Code Generator keep the keyboard where you were; in Chinese, Encrypt a file's answers, QR Code Generator's example values and Label Maker's print options are in Chinese too, and Label Maker says why its button is off.
Every page has a Report a problem button: say what you tried and what happened, add a screenshot if you like, and get a report number and a private link that shows its status. The privacy policy says what a report holds and how long it is kept.
From the nightly checks of the live pages: Regex Tester counts U+2028 and U+2029 as line ends, as its m flag does, keeps your place when a new run replaces one still running, and says plainly when Start again stops a run; JSON Formatter keeps a long string's colour up to where it is cut and states its measured time for large files; Text to Speech wraps your text on a phone and reads a Markdown file's reference links as their words; Budget Import keeps your place when you remove a target; Subtitle Shift refuses a time below zero at its own field; Trim Audio says when a fade is longer than the part, and what it applied.
Unit Converter's table of every unit stays readable on a phone, and its notes on the kati and tahil follow Singapore's Weights and Measures Act as it stands; Teleprompter keeps the keyboard inside the open prompter and keeps a focused button in view on a phone; Text Diff makes a patch that applies to a file with old Mac (CR) or mixed line endings.
In Chinese, HEIC to JPG says why a damaged HEIC photo is refused entirely in Chinese.
Reconcile Sheets writes the same report whether the page is in English or Chinese. A file that cannot be used, chosen or dropped on a table, empties that table and turns Reconcile off, and the page says why; cancelling a workbook's worksheet choice changes no table. Its answers say that a number with leading zeros, such as 0007, is matched as a code, and give their examples in Chinese.
Compare Sheets follows the same rule: a file that cannot be used, chosen or dropped on a table, empties that table, with its comparison and download, and turns Compare off, and the page says which table is empty and why. Its first step says the rule in Chinese too.
vCard Maker takes away the message about a file it could not open, as the contact or as its photo, once a download or a copy has worked; a warning that still holds, such as a contact's photo left out, stays.
If part of a tool's page does not load, the page now says so in its language, with a Reload the page button; when you were passing a file on from another tool, it adds that the file is still in the tab you came from.
In Image to PDF, Merge PDF and Create ZIP, a screen reader is told where the up and down buttons moved a file, and no old message about the order stays after a file is removed or you start again.
Matrix Transfer is in Chinese when you switch the page to Chinese: sending, the sign-in tab, My transfers, a transfer's details and the page your recipients open, with its own messages, dates and sizes in Chinese.
JSON Formatter and Text Diff say plainly when a file is too large: its size and the limit, in MB and to the byte, and what to do.
OCR scanned PDFs and images reads a table without borders row by row, as its help says: the cells that stand side by side in a row come out together, left to right, in the text file and in the searchable PDF's text layer.
Bill Splitter uses the same decimal places for each currency in every browser, as ISO 4217 sets them: an amount such as 15000.50 in Indonesian rupiah is accepted in Chrome too. The tools' package @matrixai/tools 0.1.1 follows the same table.
A new page, Products and their stage, lists the Matrix products you can use today, each with its id, phase and stage and the tools that work now. Each tool page says beside its title that it runs on your device and your files are not uploaded, with a link to what the page keeps; the home page says that this promise is the browser tools' own, since Matrix Transfer and the tools' API send files to our servers.
Calendar Event Maker opens, moves and saves a repeating event that skips many dates in seconds, up to its 5 MB file limit: moving such an event once took minutes, and one with some 150,000 skipped dates could not be saved at all.
JSON Formatter names a download after the text it holds: once you type over all of an opened file's text, the result downloads as data_formatted.json, not under the opened file's name.
OCR文字识别会按行读取无边框的表格，与帮助说明一致：同一行中并排的单元格会在文本文件和可搜索 PDF 的文字层中按从左到右的顺序一起输出。
账单分摊在所有浏览器中对每种货币使用相同的小数位数（依据 ISO 4217）：例如印尼盾金额 15000.50 在 Chrome 中也能输入。工具包 @matrixai/tools 0.1.1 也采用同一张表。
新页面产品与阶段列出现在可以使用的 Matrix 产品，以及每个产品的编号、阶段和现在可用的工具。每个工具页面在标题旁说明它在你的设备上运行、你的文件不会上传，并链接到这个页面保存什么；首页说明这一承诺只针对浏览器工具，因为 Matrix Transfer 和工具 API 会把文件发送到我们的服务器。
Edit PDF text is new: change a line of a PDF's own text where it stands. Sign PDF sizes a signature by a corner or in millimetres and adds the date or your own text; the developer page shows where to start; the home page and Matrix Transfer's first page follow 中文; Convert image names every result the same way, Date Calculator leaves out Singapore's public holidays by default in Singapore; and many tools fix what the nightly checks of the live pages found.新增编辑PDF文字：在原位置修改 PDF 中已有的一行文字。PDF签名可以拖动角或按毫米调整签名，并加上日期或自己的文字；开发者页面说明从哪里入手；首页和 Matrix Transfer 的首页跟随中文选择；图片格式转换对所有结果采用同一种命名，日期计算器在新加坡默认排除公共假期；许多工具修复了对线上页面夜间检查发现的问题。

Edit PDF text is new: change a line of a PDF's own text where it stands, such as a date, a name, a figure or a typo. The new text is written in the line's own font when that font has every character of it; when it has not, the page names the missing characters and you choose one of the tool's fonts for that line. The preview shows the page as the copy will be before you save, and a line the tool cannot change is marked with the reason.
Sign PDF resizes a signature when you drag one of its corners, keeping its proportions, or places it exactly when you type its place and width in millimetres. It can also add the date or your own text, such as your name in print, placed, moved and resized as a signature is and written into the PDF as text.
The developer page starts with where to go: the tools' API (50 tools, 63 operations), connecting ChatGPT or Claude, Transfer, and your API keys and their usage, with an example call that runs a tool. It also says that API calls, unlike the browser tools, send their inputs to our server for the run.
The home page is in Chinese when you choose 中文, its quick tasks included, and says that the browser tools keep files on your device while Matrix Transfer and the tools' API send files to our server. Matrix Transfer's first page and send form follow the same choice without losing the files chosen or the text typed, and its allowance gives the exact number of bytes left beside the rounded figures.
Convert image names every result the same way, adding _converted before the new extension whether the format changes or not: photo.png becomes photo_converted.jpg, or photo_converted.png when kept as PNG.
Date Calculator leaves out Singapore's public holidays by default when the device's time zone is Singapore's; you can untick it, and a shared link's own setting comes first.
CSV Anonymizer replaces a postal code column with a short code by default, recognising it by its header in English or Chinese (postal code, postcode, ZIP code, 邮编), codes with leading zeros or letters included.
Compress PDF describes its three choices in plain words; its answer on what each setting does keeps the exact figures.
Excel to PDF draws diagonal borders; says when a workbook has no cells to print; converts a large workbook in steps while the page keeps answering and says how far it is; and draws Chinese, Japanese and Korean text in bold or italic as bold or italic, as PowerPoint to PDF and Word to PDF now do.
Reconcile Sheets names in its summary the worksheet each table was read from.
PDF to PowerPoint brings a table's rules, its cells' fills and a frame's edges across as shapes behind the text, where the page draws them, and names what it leaves out; text on a page turned by 180 or 270 degrees is placed where it stands, and each paragraph of a text box takes its own East Asian language.
PDF to Excel reads a ruled table whose values are form fields as a table, and a 16-digit number that a narrow column wraps into two lines as one value; PDF to Word leaves a form's fields out, as its answer says; and where the browser refuses to copy, PDF to text selects the whole text for Ctrl+C.
OCR scanned PDFs and images says when a page has no printed text it can read, and what to try; correcting the text keeps one Use in another tool panel beside its download.
Teleprompter's Follow my voice can now use the microphone on this site: since the option came on 22 October, the site's own settings had refused it.
On every tool page, the language browsers and screen readers are told the page is in follows the EN / 中文 choice, and a file chosen while the page is still loading is taken.
新增编辑PDF文字：在原位置修改 PDF 中已有的一行文字，例如日期、名字、数字或错别字。只要这一行原来的字体有新文字的每个字符，新文字就用原来的字体书写；如果没有，页面会说明缺少哪些字符，由你为这一行选择本工具提供的一种字体。保存之前，预览会显示保存后的页面；不能修改的行会标出来并说明原因。
A password for Create ZIP, two columns in Resume Builder, and truer Office conversions创建ZIP压缩包可以设置密码，简历制作支持双栏，Office 文件转换更忠实于原文件
Improved改进PDFPDFFiles文件Images & design图片与设计
Create ZIP can protect a ZIP with an AES-256 password that 7-Zip, WinRAR and Keka open; Resume Builder adds a two-column layout and embeds every font; Excel, PowerPoint and Word to PDF draw more of each file as it was made; and Merge PDF, PDF to PowerPoint, Unit Converter, Subtitle Shift and Font pairs each fix a reported problem.创建ZIP压缩包可以用 AES-256 密码保护 ZIP，7-Zip、WinRAR 和 Keka 输入密码即可打开；简历制作新增双栏版式，并嵌入所有字体；Excel转PDF、PPT转PDF 和 Word转PDF 能更完整地按原文件的样子绘制；合并PDF、PDF转PPT、单位换算、字幕时间调整和字体搭配各自修复了一个已报告的问题。

Create ZIP can protect the ZIP with a password of at least 8 characters: each file's contents are encrypted with AES-256 in the WinZip format, which 7-Zip, WinRAR and Keka open with the password, and Windows' Extract All, macOS Archive Utility and this site's Extract ZIP do not. As in every ZIP, the files' names, sizes and dates stay readable; its answer on passwords says how to hide them too.
Resume Builder offers Two columns beside Classic's one, with your contact details, Skills, Languages and Certificates in a narrow column on the right; Skills can sit one per line or side by side; and every font is embedded in the PDF, Liberation Sans or Liberation Serif for Latin, Greek and Cyrillic text, so the resume looks the same in every viewer. For applicant tracking systems, its answer recommends Classic.
Excel to PDF prints the own headers and footers of a sheet's different first page and different odd and even pages, lets unwrapped text in the last used column run on over the empty cells beside it, prints separate print areas each on pages of their own as Excel does, says before converting when it does not know a sheet's paper size (that sheet prints on A4), and loads the language font for any character the PDF's built-in fonts lack, such as a Greek letter.
PowerPoint to PDF draws a slide's picture background, each slide its own picture at its own transparency, and a text box's fill and outline behind its text; leaves out every slide the presentation hides unless you tick Include hidden slides; gives each equation its own picture; and draws a gradient in its true middle colour, worked out from where its colours stop.
Word to PDF draws a picture the document stores without compression and reports how many damaged pictures could not be drawn; places a header's picture from its own paragraph, and a picture anchored in centred, right-aligned or justified text where that text puts it; and loads the language font for any character the PDF's built-in fonts lack, such as Chinese, a Greek letter or a symbol.
Merge PDF keeps every link and bookmark that names its destination leading to the right page of the merged file, also when a file's two lists of named destinations give one name to different pages; and when two files share a name, keyboard focus stays on the one you moved.
PDF to PowerPoint makes a page the PDF turns into a slide as a PDF viewer shows it, with its text at the angle you see it at.
Unit Converter's Copied goes the moment the conversion changes, by a swap, a new value or another unit, so it never stands beside a result it did not copy.
Subtitle Shift refuses a shift or frame-rate change that would move a cue past 999:59:59.999, the latest time it reads: the preview says how many cues it would affect and nothing is written, so every file it writes opens here again. No cues found no longer stands beside the summary of the text before.
Font pairs keeps two font files of one family apart, such as a Regular for the heading and a Bold for the body, in the preview and the sample sheet; while Base size or Heading weight holds a value it cannot use, a note above the sample says which value it keeps; and a font file chosen while the sample's ZIP is offered takes that download away at once.

View all 3 changes查看全部 3 项更新
Batch rename says once, in plain words, what is wrong with a rule it cannot use, under Find or under the numbering's fields, and the summary and the bar beside the button point to it; a file that is no rule preset says what to open instead; the preview's CSV opens Chinese names correctly in Excel; and its answer to Can I undo? says what no browser can prevent: a file another program writes at a new name in the instant between the page's last look and the rename is replaced, and Undo cannot bring it back.
Encrypt a file's strength estimate recognises common passwords, English words and names, keyboard patterns, repeats, sequences and dates, judges the passphrase in the form the key is made from, and names what it found, never the text; Start again now empties both passphrase fields.
The tools' API answers a file over its 700 KB limit with 413 FILE_TOO_LARGE naming the file and its size, and files over the limit together with their total, as its guide says.
Quote and Invoice Maker shows its form one section at a time on a phone; the PDF tools name the part of a page list they cannot use; several file tools save all their results in one go; and Clean PDF metadata finds the metadata on every page.报价单与发票在手机上一次显示表单的一个部分；PDF 工具会指出页码列表中无法使用的部分；多个文件工具可以一次保存全部结果；清除PDF元数据会找出每一页上的元数据。

Quote and Invoice Maker lays its form out in five sections: all open on a wide screen, one at a time with Next and Back on a phone, and each closed section says what it holds and how many of its fields need fixing.
Skip to content now moves the focus to the page's content, and after a run the result takes the focus and comes into view; on the PDF tools a page list that cannot be used holds the Run button and the reason names the part, such as 04; long file names keep a readable part of their row; and a skipped file is named with the files the page opens.
Decrypt a file and Clean Office metadata save several results at once with Save all to a folder (Chrome, Edge) or Download all, and Decrypt a file's Start again empties the passphrase.
Create ZIP's Start again resets the name and the compression, and files chosen from one folder name the ZIP after it until you type a name; Extract ZIP says how many files were extracted and how many failed their check.
Split and join files recognises one part of a split file chosen on its own, switches to Join and asks for the other parts.
QR Code Generator keeps the error-correction level you chose when the logo fits it, says why when it cannot, and reads phone and SMS numbers typed in full-width digits.
Bill Splitter starts a new split in the currency of the device's time zone, or of the browser language's region, and says why; its FAQ explains the automatic choice and its limits, and full-width digits are read.
Clean PDF metadata finds and removes the XMP metadata of every page, not only the document's, and of the PDF's other parts, such as graphics, annotations and bookmarks, except pictures, fonts and attachments, whose XMP it names and keeps; it lists the pages that carry XMP with up to three of the creators named there and how many more.
vCard Maker lets you choose at the top what to make, a contact file, a QR code, an email signature or a meeting background, and shows the fields that one uses, with the rest under More details; a .vcf file cut short still opens, and the page says it may be incomplete and what it read from it; the contact's note goes into the QR code only when you tick Put the note in the QR code.
Label Maker refuses a list in which text follows a quoted cell's closing quote, naming the line, instead of joining the two; it measures text as the PDF draws it, so the text stays inside its label, ends text cut off at a label's foot with an ellipsis, and names a label too small for one line of 5 pt text before making any PDF; and a first line set in bold now has bold Latin letters also when the labels need the Chinese, Japanese and Korean font, whose characters stay regular.
列表中带引号的单元格在结束引号后还跟着其他文字时，标签制作会拒绝并指出是哪一行，而不会把两者连在一起；它按 PDF 实际绘制的方式测量文字，所以文字留在标签以内，在标签底部被截断的文字以省略号结尾；标签小到放不下一行 5 pt 文字时，会在生成任何 PDF 之前指出；第一行设为粗体时，即使标签需要中文、日文和韩文字体，其中的拉丁字母现在也是粗体，而中日韩字符仍是常规字重。
The PDF tools let you choose and order pages and files on their pictures, by mouse, touch or keyboard; Teleprompter can follow your voice; the sheet tools say where a CSV quote goes wrong; and the API keys page names the tool each call ran.PDF 工具可以在缩略图上用鼠标、触摸或键盘选择和排列页面与文件；提词器可以跟随你的声音；表格工具会指出 CSV 引号出错的位置；API 密钥页面会写明每次调用运行的工具。

Organize PDF moves a page anywhere by dragging it with a mouse or a finger, or with the keyboard, and several pages can be chosen at once; Extract pages and Split PDF let you pick pages and split points on the pages' pictures.
Image to PDF and Merge PDF put the files in order by dragging or with the keyboard, each shown with its picture; Merge PDF keeps each file's bookmarks and form fields, and Crop PDF's box can be dragged by its edges and corners.
Teleprompter can follow your voice and scroll as you read, where the browser recognises your language on your device.
CSV to JSON keeps its common options in one compact row and converts again as soon as a setting changes, so a result never shows older settings.
CSV Anonymizer offers its choices in plain words, in three groups with the suggested one marked, and shows an example for each column.
Batch rename: where the browser cannot rename files in a folder, the renamed copies go to the share sheet or are downloaded one by one, and the Undo of the last rename in place still works after files are moved, removed or added.
Text Diff puts Open one or two files first on a phone, before the two editors.
Small fixes from the nightly checks of the live pages in Rotate PDF, Sign PDF, PDF to Word, PDF to text, JSON Schema Validator, Mock Data Generator, SQL on CSV, CSR Generator and Webhook Signature Verifier.

Every tool page can be used in Chinese: choose 中文 at the top of a tool page and its labels, hints, messages, results and questions follow. The choice is kept in this browser.
OCR scanned PDFs and images reads printed English and Simplified Chinese inside your browser and gives you the text and a searchable PDF that keeps each page.
Word to PDF, PowerPoint to PDF and Excel to PDF turn documents, presentations and workbooks into PDFs laid out as Office lays them out. The files are read inside your browser.
HEIC to JPG turns iPhone photos into JPEGs on your device. Safari 17 or later opens HEIC; on other browsers the page says what to do instead.
Rotate PDF shows every page as a thumbnail to turn, Crop PDF can remove what is cropped away, Compress PDF shows each level's size before it runs, and Sign PDF can type your name in three styles.
Add page numbers and Add a text watermark show a preview of the first chosen page, with a choice of font, and the watermark can also be a picture.
JSON Formatter shows a tree with line numbers and colours, Text Diff adds a side-by-side view, Regex Tester explains a pattern piece by piece, and Markdown Preview colours code, shows footnotes and saves as PDF.
CSV to JSON keeps phone numbers that start with + and reads a workbook's numbers as Excel shows them, and CSV Anonymizer replaces a street-address column with a short code by default.
Convert Audio can also make MP3, Join Audio's crossfade keeps the level even, and Clean Up Audio can estimate the noise of speech that never pauses.
Extract ZIP keeps each file's folder and reads the Chinese names Chinese Windows writes, and Time Zone Compare can keep your cities in this browser and copy a link to the comparison.
On the tools page, the PDF filter lists every tool that takes PDFs, Chinese words such as 幻灯片 find the PowerPoint tools, a search no tool answers says so plainly, and a misspelling such as “comprss” asks whether you meant “compress” and shows its tools.
Passing a result to another tool with Use in another tool no longer shows a false note that a setting of the link was ignored, and the home page has an EN / 中文 switch that keeps the language you chose on the tools pages.
QR Code Generator can be opened with a link that fills in every field, a Wi-Fi network's included, and its batch list names the line of a cell it cannot read instead of making a ZIP.
The tools' API for developers, and the tools in Claude面向开发者的工具 API，以及在 Claude 中使用工具
New新增Text & developer tools文字与开发工具
Developers can now run 50 of the tools on our server through an API, with an API key, and Claude can run them in the chat once you connect it.开发者现在可以使用 API 密钥，通过 API 在我们的服务器上运行其中 50 个工具；连接 Claude 后，它也可以在聊天中运行这些工具。
View all 4 changes查看全部 4 项更新
The tools' API provides 50 of the tools as 63 operations on our server, using the same engines as the tool pages. Send a tool's settings and its files in one request with your API key: the answer holds the result and every file the tool made. The guide lists each operation with its settings and limits.
Each run is processed on our server in a separate process that has no network access and ends with the run. Files sent in a request are held in memory for the run only and are not stored, and the files a tool makes are sent back in the answer and are not kept. The tool pages stay as they are: they run in your browser and never upload your files.
Encrypt a file, Decrypt a file and the CSR Generator are not offered on the API, so their passphrase or private key never leaves your device. The privacy policy says what we keep for each call: a usage record, never your files or their names.
The same tools also run in Claude once you connect it to your Matrix account. A tool that works on your files opens the Matrix panel in the chat: the files you choose there go from your device to our server for that run only, and the result comes back to the panel for you to download. We keep neither your files nor the result. ChatGPT follows once it has been checked the same way.
工具 API 以 63 项操作在我们的服务器上提供其中 50 个工具，使用与工具页面相同的引擎。用你的 API 密钥在一个请求中发送工具的设置和文件，响应中包含结果以及工具生成的每个文件。指南列出了每项操作的设置和限制。

Trim Audio: choose the part to keep by dragging across the waveform or clicking near an edge, and hear it with Play selection before trimming.
Trim Audio and Join Audio can save MP3 at 64 to 320 kbps, made on your device by the LAME encoder; the page says how much silence MP3 adds at the start.
Date Calculator: working days can also leave out Singapore’s public holidays, from the Ministry of Manpower’s list for 2018 to 2027, and the result names each day left out.
Fixes: Reconcile Sheets says a negative tolerance must be zero or more; Quote and Invoice Maker names the field holding a character the PDF cannot draw; the image tools say 16,384 px is the tool’s own limit; Device mockup and SVG optimiser write “1 enlarges”, not “1 enlarge”.

Create ZIP says why a file was stored as it is (it did not shrink, deflate would make it larger, or it is empty), instead of calling a small text file “already compressed”, and handles the full 65,535 files a ZIP can hold.
Date Calculator states its own limits: amounts up to 1,000,000 each, dates from the year 1 to the year 275,760; a result beyond them is refused in those words.
创建 ZIP会解释文件为何原样存储：压缩后未变小、deflate 会使文件更大，或文件为空。不再把小文本文件笼统称为“已压缩”。支持 ZIP 格式的 65,535 个文件数量上限。

On the tools pages, choosing English or 中文 when it differs from your browser’s language is now remembered in your browser, so the next page opens in that language; choosing your browser’s language again forgets it. The privacy policy says so.
在工具页选择不同于浏览器默认语言的 English 或中文后，浏览器会记住该选择，下一页会使用所选语言。再次选择浏览器默认语言会清除该偏好。隐私政策已说明这一点。
Run more complex queries, with clearer guidance for unsupported SQL and a 20-second time limit.支持更复杂的查询；不支持的 SQL 会给出改写提示，运行超过 20 秒会停止。

SQL on CSV runs far more of SQL: sub-queries, WITH (also recursive), UNION, INTERSECT and EXCEPT, RIGHT and FULL JOIN, and window functions, with answers that follow SQLite’s. What it does not support is refused with a note on what to write instead, and a query still running after 20 seconds is stopped with a message.
CSV to JSON keeps one type per column: when a value such as 007 must stay text, the column’s other values stay text too, and the page names the column.
Write Chinese in PDFs, find tools in everyday language and get clearer guidance when an action is unavailable.在 PDF 中写入中文，用日常说法查找工具，并了解操作不可用的原因。

The tools page lists Matrix PDF first, names every section and tool in Chinese too, finds tools by everyday words such as “shrink pdf” or 转word, and shows the tools coming soon.
Every tool page has an English / 中文 switch, and when the main button is greyed out, a line beside it says why.
A result always belongs to what you entered: changing the text or an option removes the earlier result. CSV to JSON keeps every number exact: a value JSON cannot hold exactly, such as 123456789012345.68, stays text.
The home page starts from tasks, and making apps is described on its own page. The site no longer links to desktop downloads.
Add a text watermark, Add page numbers and Fill PDF form write Chinese, Japanese and Korean, loading a 2.3 MB font for common Chinese and the full font only when needed; page numbers can take your own label, such as 第 {n} 页 / 共 {p} 页.
Sign PDF places several signatures in one save, or one signature on every page; Fill PDF form lists each field by its label and numbers it on a preview of its page.
Quote and Invoice Maker’s credit note gives back the invoice’s discount in the same share; CSV Cleaner and Compare Sheets write files that Excel opens with Chinese intact; Reconcile Sheets compares up to two more columns for each key and reads Chinese headers.
Regex Tester stops a pattern still running after 3 seconds and says why; Markdown Preview pauses its live preview for very long text; JSON Schema Validator says “Not fully validated” when a schema uses rules it cannot check, and can be stopped; Mock Data Generator loads its presets.
Convert Audio to WAV filters properly when it lowers the sample rate and keeps files of the same name apart; Clean Up Audio reports what really changed; Trim Audio’s Start again resets its fades; Subtitle Shift lets you add and move cues.
Annotate a screenshot keeps its choices beside the picture on wide screens; SVG optimiser shows the original and the result side by side; Compress image makes PNG files smaller with a palette of up to 256 colours; Label Maker prints Chinese.
Batch rename numbers files from a pattern such as holiday-{n}; Budget Import opens Excel statements, lists transfers and card repayments for you to leave out, and keeps your monthly targets in your browser only if you tick that box; Bill Splitter lets a person added later share earlier expenses; Resume Builder prints Chinese whole and within the margins.
工具页将 Matrix PDF 放在首位，每个分类及工具都有中文名称；可用“shrink pdf”或“转word”等日常说法搜索，也会显示即将推出的工具。

Compress PDF keeps a sideways phone photo the way it sits in the PDF, and Image to PDF leaves out a photo’s hidden details, such as where it was taken, and says what it left out.
Cron Explainer shows the meaning right under the expression, and Font pairs’ sample image keeps Chinese inside its margins and grows up to 13,900 px tall, naming anything that does not fit.
压缩 PDF会保持手机照片在 PDF 中原有的方向；图片转 PDF会移除照片中的隐藏信息（如拍摄地点），并说明移除了什么。
