What Does Splitting a PDF Mean?

Splitting a PDF breaks a multi-page document into smaller pieces. You can split every page into its own file, divide the document at specific page boundaries, or extract only the pages you need into a new PDF.

Three Ways to Split a PDF

1. Split All Pages

Converts a single PDF into as many individual PDF files as it has pages. A 10-page PDF becomes 10 one-page PDFs. Useful when each page is an independent document — invoices, certificates, or scanned forms that need to be distributed separately.

2. Split by Ranges

Divides the PDF at specified page boundaries. For example, entering 1-5,6-10 produces two PDFs: one covering pages 1–5 and another covering pages 6–10. Ideal for splitting chapters, sections, or quarterly reports into separate files.

3. Extract Specific Pages

Pulls individual pages from anywhere in the document into a single new PDF. Enter 1,4,7 to get a three-page PDF containing only pages 1, 4, and 7 of the original. Perfect for sharing selected slides or pulling relevant pages from a large manual.

Frequently Asked Questions

How do I split a PDF into separate pages?
Upload your PDF, choose "Split all pages", and click Split PDF. Each page is saved as its own PDF and downloaded as a ZIP.
Can I split a PDF by specific page ranges?
Yes. Choose "Split by ranges", enter ranges like 1-3,4-6, and each range becomes its own PDF. Multiple ranges are bundled in a ZIP.
How do I extract specific pages from a PDF?
Choose "Extract specific pages", enter page numbers separated by commas (e.g. 1,3,5), and download a single PDF with only those pages.
Are my files safe?
Yes. Everything runs in your browser via pdf-lib. Your file is never uploaded to any server.
Why does my split PDF download as a ZIP?
When splitting produces multiple files they are bundled into a ZIP. A single-range split or single-page extract downloads directly as a PDF.
Can I split an encrypted PDF?
Owner-restricted PDFs generally work. User-password-locked PDFs must be unlocked first.
Is there a page count limit?
No hard limit. Very large PDFs may take longer since processing is local. Split in smaller batches if needed.
What page numbering is used?
Pages are numbered from 1. Page 1 is the first page of your PDF.
