合并 PDF — 免费无限、离线处理不上传

在浏览器里合并 PDF。免费无限次，不上传、免注册、无水印。文件完全不离开你的电脑。

Merge PDF files directly in your browser. Free, unlimited, and completely local — your documents are never uploaded anywhere. No sign-up, no watermarks, and no permissions requested. Drop in as many PDFs as you like, drag them into the order you want, and download the result. That's the whole tool. There is no step where the price changes. A PDF combiner that works offline: join two documents or a hundred, in any order, without sending a single byte to a server. WHY THIS EXISTS Most PDF tools ask for money after you have already done the work — after you have dragged in the files, put them in order, and pressed the button. Many of them also send your documents to their own servers to do the work, which is not obvious from the install screen. This one does neither. Joining files is free and unlimited, permanently. And nothing is uploaded, because the PDF engine is bundled inside the extension and runs on your machine. EVERYTHING STAYS ON YOUR COMPUTER • Files are read from disk, assembled in memory, and saved back — locally • The extension makes no network requests at all • It works with your internet disconnected • Nothing is stored, logged or transmitted You do not have to take our word for it. Open the workspace, press F12, select the Network tab, and combine something. Every request you see will be one of the extension's own bundled files. ZERO PERMISSIONS This extension requests no Chrome permissions whatsoever. It cannot read the pages you visit, your history, your bookmarks, your cookies, or anything in your other tabs. Chrome will confirm this on the install screen. WHAT YOU CAN DO • Combine multiple PDF files into one document • Join scanned pages, invoices, contracts or reports into a single file • Drag and drop to set the exact order — top to bottom, exactly as listed • See the page count and size of each file before you commit • Remove individual files, or clear the list and start again • Name the output file whatever you want • No limit on how many files, pages or megabytes • Works offline — no internet connection needed • Light and dark themes, following your system • Available in 16 languages GOOD TO KNOW Password-protected PDFs are rejected when you add them, with an explanation, so the job never fails halfway through. Remove the password first and they will work. Damaged files and non-PDF files are reported by name rather than silently skipped. FREE, AND STAYING THAT WAY Merging PDFs is free and unlimited. Paid features may be added later for things like batch processing or password removal — putting files together will never become a paid feature.
