How do I write a page range?

Use commas and dashes. Example: 1-3, 5, 7-9 produces three PDFs: pages 1 to 3, page 5 alone, and pages 7 to 9. Pages are 1-indexed.

Burst extracts every page to its own PDF — useful when you need each page as a separate file (one signature per signer, one invoice per page).

Can I split every N pages?

Yes. Pick Every-N and set the chunk size. A 12-page PDF split every 4 pages produces three files: pages 1-4, 5-8, 9-12.

Are my PDFs uploaded?

No. Splitting runs entirely in your browser using pdf-lib. The file bytes never leave your device.

About PDF Splitter

Splitting PDFs comes up constantly: extracting only the signed pages from a contract, separating an annual report into chapters, isolating a single invoice from a monthly batch, or pulling one page out to share without leaking the rest.

This splitter runs entirely in your browser using pdf-lib. Three modes cover the common cases: Ranges accepts a comma-separated list like '1-3, 5, 7-9' and produces one PDF per range. Every-N chops the PDF into equal-size chunks. Burst extracts every page as its own PDF.
