Split PDF
Extract chapter 3 from a manual, pull one signed page from a contract pack, or burst a scan into single-page files. Splitting runs in your browser with pdf-lib — your document never leaves the device.
How to split a PDF
1. Upload the PDF file.
2. Choose split mode: page range, every N pages, or all pages separately.
3. Enter page numbers or ranges (e.g. 1-3, 5).
4. Download the resulting PDF file(s).
Split examples
Send only your pages
A 40-page board pack includes everyone’s appendix — split pages 12–15 which are yours to email.
Burst for e-signature
Split a batch scan so each recipient gets exactly their signature page.
Course handouts
Split a combined weekly PDF into one file per student group.
When to split PDFs
• When recipients need only part of a large document.
• When re-ordering or merging subsets later.
• When a portal caps attachment size — split then send in parts.
Limitations
• Password-locked PDFs must be unlocked first.
• When you need to edit text inside pages — use a desktop editor.
• When split order must preserve complex bookmarks — verify output navigation.
Range planning
Open the source in a reader and note page numbers as displayed — some PDFs use roman numerals for front matter; tool page indices are usually sequential from 1.
Privacy for contracts
Splitting locally avoids uploading confidential M&A or HR PDFs to cloud splitters — prefer on-device tools for sensitive docs.
Combine with extract
Extract PDF pages overlaps with split for single ranges — pick whichever UI matches your mental model; result is similar.
Frequently asked questions
Can I split password-protected PDFs?
Usually not until decrypted locally in trusted software.
Are files sent to a server?
No — splitting is local.
Page range syntax?
Common formats: 1-5, 7, 10-12 for pages 1 through 5, page 7 alone, and 10 through 12.
Does splitting reduce quality?
Pages are copied as embedded content — not re-rendered as images.
Merge splits back?
Use merge PDF to recombine in any order.
Max file size?
Limited by browser memory — split very large files on desktop with ample RAM.
