About Split PDF
PDF Split turns one PDF into several. There are six modes: custom ranges (each its own file, or merged into one), a new file every N pages, every page on its own, selected pages, odd and even pages in two files, or one file per bookmark at one or two levels. Before you split, a line tells you how many PDFs will be created, and a range that does not exist is refused with the reason. Each part keeps its form fields, title and author, and the bookmarks of its pages. Parts are made in your browser with pdf-lib, then offered one by one or as a ZIP.

Where your file is processed
Splitting happens in a Web Worker inside your browser, and the ZIP of all the parts is assembled there too; your PDF is not uploaded to our servers. A PDF with print or copy restrictions is decrypted there first, and one that asks for a password to open is refused with a pointer to Unlock PDF.
Frequently asked questions
Can I split a PDF by chapters?
Yes, if it has bookmarks. Choose By bookmarks: each top-level bookmark starts a new file, or pick two levels to cut at sections too. Pages before the first bookmark get their own file, and each part is named after its bookmark.
Can I extract only some pages into one PDF?
Yes. Choose Select pages, type them, for example 2, 5, 9-12, and check Merge the extracted pages into one PDF. Without that box, each selected page becomes a file of its own.
Can I split into parts of equal size?
Yes, by page count. Every N pages makes a new PDF every N pages and the last one holds what is left; the number must be smaller than the page count. Splitting by size in megabytes is not offered.
Do I have to download each part separately?
No. When there are two or more parts, Download all saves them in one ZIP named after your file; each part also keeps its own Download button.
Tips and tricks
- ✓Every page on a long PDF creates many files: take them as one ZIP rather than one by one.
