Split one PDF into several, right in your browser

Splitting is how a 200-page scanned bundle becomes the six pages someone actually asked for. Free tools usually cap this exactly where it hurts — Sejda's free tier stops at 50 pages, which is precisely the size of document that needs splitting.

Click page thumbnails to pick pages (Shift-click selects a run), type a range, split at a fixed interval, split at the PDF's top-level bookmarks, or cap each part at a size you set. You see the page thumbnails while you choose, so you're not guessing at page numbers — which is the difference between splitting a document once and splitting it three times because pages 40-52 turned out to be pages 41-53.

Ranges accept the notation you'd expect: 1-3, 7, 10- means the first three pages, page seven, and everything from page ten to the end. Splitting at a fixed interval is the one you want for a batch of scanned two-page forms that came through as a single file, and splitting by size is for chopping something oversized into email-sized pieces: each part is built and measured, so none is over your limit unless a single page is bigger than it, and then we tell you.

What this does — and what it doesn't

  • Splitting rebuilds each output document, so interactive form fields are not carried into the parts.
  • Bookmarks that point into a section you didn't keep are dropped along with it.
  • Split by bookmarks uses top-level bookmarks only, and only those that jump to a page inside the document.
  • The part count shown before a split by size is an estimate; the real sizes are measured while splitting. Password-protected files must be unlocked first.

Split PDF — frequently asked questions

Can I split by page range?
Yes. Click the page thumbnails or type ranges like 1-3, 7, 10-, and the two stay in step. You can also split every N pages, one page per file, at bookmarks, or by maximum file size.
How does splitting by bookmarks work?
Each top-level bookmark starts a new file that runs to the page before the next one, named after the bookmark. Pages before the first bookmark become their own file.
Can I split a PDF into parts under a size limit?
Yes, for example parts under 10 MB. We build each part and measure it, so none exceeds the limit unless one page is bigger than the limit by itself, in which case that page gets its own file and we say so.
Is there a page limit?
No. The document is processed on your device, so the only ceiling is your available memory.
Is my PDF uploaded anywhere?
No. Every operation runs in your browser using JavaScript and WebAssembly — the file never leaves your device. You can verify it: load the page, disconnect from the internet, and the tool still works. There is no upload endpoint to send it to.
Is it really free? What's the catch?
It's free because it costs us almost nothing to run: there's no server doing the work, so there's no per-file cost to recover. No account, no watermark, no daily task limit, and no feature that turns out to be paid at the download step.
