When to split a PDF
Send someone only the pages they need. Split a 40-page contract into signature pages and appendix, or carve one chapter out of a report for a teammate.
Because files are processed on your device, splitting confidential documents — legal filings, medical records, IDs — never exposes them to a third-party server.

Frequently asked questions
How do I split a PDF into individual pages?
Choose the “Every page” mode and click Split PDF. You get one file per page, bundled in a single ZIP download.
Can I split by custom page ranges?
Yes. Type ranges in the box, separated by commas — for example 1-3,5,8-12. Each range becomes its own output file, in the order you typed them.
Does splitting a PDF reduce its quality?
No. Pages are copied losslessly from the source document. Text stays selectable, fonts and images are untouched.
Is there a file size or page limit?
No fixed limit. Splitting runs locally in your browser, so the practical ceiling is your device memory — files up to a few hundred MB work fine on most computers.
Can I split a password-protected PDF?
Encrypted files must be unlocked first. Run your document through the free Unlock PDF tool with your password, then split the unlocked copy.
Why do I get a ZIP file instead of one PDF?
Splitting produces multiple PDFs, so they are bundled into one ZIP for a single download. Every modern system opens ZIP files natively.
