Split a PDF into parts — extract specific pages, chunk every N pages, or explode into one file per page. Page thumbnails preview what you're splitting. Output downloads as a ZIP (or single PDF for range extraction).

What people split PDFs for
Book chapters
Break a textbook into per-chapter PDFs so students only get the section they need.
Invoice pages
Extract only the pages that matter from a 40-page accounting export.
Contract sections
Send only the signed signature page to one counterparty, only the schedule to another.
Batch printing
Chunk a long report into 10-page groups for double-sided printing in separate binders.
How to split a PDF in 4 steps
- Drop your PDF into the upload area. We read the page count + show a first-page thumbnail locally — the file never leaves your browser until you submit.
- Pick a split mode: Every page, Extract pages (1-3, 5, 7-10), or Every N pages.
- Confirm the cost in the quote card. Every-page and every-N return a ZIP of parts; extract-pages returns a single PDF.
- Click Split PDF and download the ZIP (or PDF). We store it for 24 hours — 7 days for active credit holders.

PDF Splitter — FAQ
Upload one PDF, split it into smaller PDFs. Three modes: one file per page (explode), extract a custom page range (e.g. pages 1-3, 5, 7-10 into a single new PDF), or chunk every N pages into groups. Multi-file outputs download as a ZIP; range extraction downloads as one PDF.
Flat 200 tokens base plus 10 tokens per output part — a 20-page every-page split costs ~400 tokens, a range-extract costs the 200-token floor. The exact quote appears under the mode picker before you hit Split. Free users get 2,500 daily tokens.
Up to 50 MB per upload. For larger PDFs, compress first at /pdf/compress/ (drops images to 150 DPI) or run PDF Splitter on the chunks. A 50 MB PDF is unusual for text-heavy docs; that size usually means scanned images.
Pick "Extract pages" and type a range: commas separate individual pages, dashes denote ranges. "1-3, 5, 7-10" gives you pages 1, 2, 3, 5, 7, 8, 9, 10 in one PDF preserving their original order. You can also click the page thumbnail strip below the upload preview to auto-insert numbers.
Chunks the PDF into equal stretches — N=5 on a 23-page PDF gives you 5 ZIP entries: pages 1-5, 6-10, 11-15, 16-20, and 21-23. Useful for batch printing or sending a report to five different reviewers without each seeing the whole document.
Yes. We use pikepdf (C-based qpdf bindings) which preserves form fields, annotations, bookmarks, and embedded fonts across the split. The output PDFs are byte-accurate copies of the source pages.
We detect password protection on upload via PDF.js in your browser and show a clear error — nothing is uploaded. Use /pdf/unlock/ first if you own the document and know the password.
PDFs are written to a temp directory on our API server for the split, then deleted. The ZIP/PDF output is kept on our CDN for 24 hours (7 days with active credits) at a share link in your dashboard.
You can split a signed PDF into chunks, but splitting invalidates the cryptographic signature on the pages that were re-composited. If the signature matters legally, split first, then sign, not the other way around. Our /pdf/sign/ tool reapplies sigs to the output if needed.
Yes — type the pages in the order you want in "Extract pages" (e.g. "3, 1, 2" returns a PDF with page 3 first). For full drag-to-reorder with thumbnails, use /pdf/merge/ with the input as a single file.
Free.ai is free and covers all three split modes (every-page, range, every-N). Smallpdf ($9/mo) and iLovePDF ($7/mo) require sign-up and lock their API behind enterprise contracts. We expose /v1/pdf/split/ publicly with bearer-token auth — see /api/.
Yes — POST multipart to /v1/pdf/split/ with file + mode + (pages or chunk_size). Quote endpoint /v1/pdf/split-quote/?pages=N&mode=M returns the exact cost before you upload. Full curl recipe at /api/.
