Split a PDF
Pull out the pages you need, cut a document into parts, or split every page into its own file. See real page previews first. Everything happens in your browser, so your file is never uploaded.

How it works
Your browser downloads two small toolkits and runs them locally: pdf.js draws the page previews you tap through, and pdf-lib builds the file you download.
Only the previews touch pdf.js, and only to draw pixels on screen. The pages you actually get are built by pdf-lib copying the original page content across directly, not re-rendering it, so text stays selectable and images keep their resolution regardless of how the thumbnail looks.
Because the work happens on your device, there is no upload, no queue, and no server holding your document.
Questions
Will my pages lose quality?
No. Page content is copied across exactly, not re-rendered, so text stays selectable and images keep their original resolution. The small thumbnails you tap to choose pages are a separate, low-resolution preview and have no effect on the file you download.
Are my files uploaded to a server?
No. Both the page previews and the actual splitting happen inside your browser, using pdf.js for the thumbnails and pdf-lib for the output, which your browser downloads once and runs locally. Your file never leaves your device.
What is the difference between the three modes?
The "Keep pages" tab (extracting pages, in PDF terms) pulls the pages you choose into one new PDF, in their original order. "Split at points" cuts the document into several PDFs wherever you place a break, delivered together in a zip. "Every page" is the same idea taken all the way: one PDF per page, zipped.
What happens to bookmarks or the table of contents?
Page content, page sizes, and orientation all carry across exactly. Document-level extras such as bookmarks, the outline, and interactive form fields are not copied, so each result is a clean set of pages rather than a rebuilt interactive document.
Can I rotate or reorder pages while splitting?
Not in this version. Pages come out in their original order and orientation. If you need pages combined in a different order afterwards, the merge tool lets you set your own order. Merge PDF files.
Why do the thumbnails look a bit soft?
They are rendered small on purpose, since they only need to help you tell pages apart, not to be read from. Keeping them small keeps the preview fast even on a long document.
What does "Compress this PDF first" do on the result?
For a "Keep pages" result, it sends that PDF straight to the compress tool without you having to download it and pick it again. It is not offered for "Split at points" or "Every page" results, since those come out as a zip of several files rather than one PDF. The file is held briefly in your browser’s own storage, never sent anywhere, and is deleted the moment the compress tool loads it.
