Split PDF
Split a PDF by range, into equal-sized chunks, or at the exact pages you choose.

Nothing is uploaded. The file is read in this page.
Comma-separated groups. Each group becomes its own file, e.g. 1-3,5,8-10.
Comma-separated page numbers to cut after, e.g. 3,7 on a 10-page file gives three files.
Add a PDF, choose a split method, then check the preview before splitting.
Everything here runs on your device. Nothing you enter is uploaded or stored.
Split one PDF into several files three different ways: by explicit page ranges, into equal-sized chunks of every N pages, or at exact break points you choose. See how many files will be produced before you commit, then download them as a ZIP.
How to use it
- Drop or choose the PDF you want to split.
- Pick a split method: Range for specific page groups, Every N pages for equal chunks, or Break points for exact cut locations.
- Enter your ranges, chunk size, or break points. The preview updates live to show how many files will result.
- Press Split. A single result downloads directly as a PDF; multiple results download together as a ZIP.
Three ways to describe a split, because “split a PDF” means different things
Range mode treats each comma-separated group as a complete, independent output file. Typing 1-3,5,8-10 produces exactly three files: pages 1 through 3, page 5 alone, and pages 8 through 10. This is the mode for pulling out specific, named groups of pages — a chapter here, an appendix there — where the groups don’t need to cover every page in the document.
Every-N-pages mode is for the opposite case: a long document that needs to become equal-sized pieces, with no manual range-typing. A 40-page report split every 10 pages becomes four 10-page files, in order, covering every page exactly once.
Break points mode sits between the two. Rather than naming ranges, you name the cut locations — “after page 3, after page 7” on a 10-page document produces three sequential files (pages 1-3, 4-7, 8-10) that together cover the whole document with no gaps and no overlaps. This is the natural mode when you’re thinking “cut here” rather than “these pages belong together.”
Why the preview matters before you commit
Getting a page range wrong is a common and frustrating mistake — a typo turns 1-10 into 1-1,0, or an off-by-one in a break point shifts every subsequent file’s contents. Rather than discovering the mistake in the downloaded files, this tool computes and displays exactly how many files will be produced and how many pages each one contains, updated live as you type. If the preview says “3 files: 4 pages, 3 pages, 1 page” and you expected four even groups, you know to fix the input before spending the download.
What it does not do
It does not split by content — there is no way to say “start a new file whenever you see a blank page” or similar automatic detection; every split location is one you specify explicitly. It does not merge the resulting files back with any bookmarks or a table of contents describing the original structure. Splitting an encrypted PDF requires removing the password first, using PDF Unlock if you have permission to do so.
Split mode comparison
| Mode | You specify | Best for |
|---|---|---|
| Range | Named page groups, e.g. 1-5,10,15-20 | Pulling out specific chapters or sections |
| Every N pages | A chunk size, e.g. 5 | Equal-sized pieces from a long document |
| Break points | Cut locations, e.g. 3,7 | Dividing a continuous document at known boundaries |
Common split scenarios
| Scenario | Recommended mode |
|---|---|
| Extract chapters 2 and 4 from a book | Range: [chapter 2 pages],[chapter 4 pages] |
| Break a 100-page scan into 10-page batches for review | Every N pages: 10 |
| Divide a merged document back at its original file boundaries | Break points, at each boundary |
| Pull out just the appendix | Range: single group covering the appendix pages |
Questions
What is the difference between range mode and break points?
Range mode treats each comma-separated group ("1-3,5,8-10") as its own complete output file — three files in that example. Break points mode instead describes where to cut a continuous document, so "split after page 3 and after page 7" on a 10-page file produces pages 1-3, pages 4-7, and pages 8-10 as three sequential files.
Can I split into files of exactly N pages each?
Yes, that's every-N-pages mode. A 25-page document split every 5 pages produces five 5-page files. If the page count doesn't divide evenly, the final file gets whatever pages are left over.
What happens if my range groups overlap or skip pages?
Range mode processes exactly the groups you specify — overlapping ranges will include the same page in more than one output file, and any pages not mentioned in any group simply won't appear in any output. This is deliberate, letting you extract specific groups without being forced to account for every page.
How many files can this produce at once?
There's no fixed cap, though producing dozens of very large output files is bounded by your device's memory, since everything happens in the browser rather than on a server.
