Overview
What this tool does
Splitting a PDF means turning one PDF into several smaller PDFs. Two common modes: extract a range of pages (e.g. "give me just pages 1 to 3 and page 7" from a 50-page report), or burst the document so every page becomes its own file (useful for separating scanned pages, splitting a packet of forms, or processing pages one at a time in a downstream tool). The splitter runs entirely in your browser using pdf-lib. The original PDF stays on your device. No upload, no signup, no daily limit, no watermark on the output. Useful for legal teams extracting exhibits from a long brief, students cutting a textbook chapter for offline reading, or anyone who needs just a few pages from a long doc.
How to
Use it in 3 steps
- Drop the PDF on the page (or click 'Pick PDF').
- Pick a mode: 'Extract pages' to get a single PDF with selected pages, or 'One PDF per page' to get a ZIP with one PDF per page.
- For extract mode, type the pages you want as ranges. Examples: '1-5' for pages 1 to 5; '1, 3, 7' for those three pages; '1-3, 5, 7-9' for a mix.
- Click the download button. The result is built in your browser and saved to your downloads folder.
FAQ
Frequently asked questions
▶Is my PDF uploaded?
No. The file is loaded into your browser's memory, processed by pdf-lib on your device, and the output is written straight to your downloads. Nothing reaches a server.
▶What's the format for the page-range field?
Comma-separated. Each entry is either a single page (e.g. '5') or a range with a hyphen (e.g. '3-7'). Whitespace around commas and hyphens is ignored. Pages outside the document's actual page count are silently dropped.
▶How big can the input PDF be?
There is no hard limit. Splitting is constrained by your device's memory. A 500-page PDF splits in a few seconds on a modern desktop; a 5000-page PDF may take a minute or run out of memory on a phone.
▶Does the output PDF keep the original quality?
Yes. Pages are copied page-by-page using pdf-lib's lossless copyPages, so the text, images, and vectors in the output are identical to the input.
▶Can I split a password-protected PDF?
Yes for owner-encryption (the common case). PDFs that require a user password to open need to be unlocked first.
