How to split a PDF into separate files
Splitting is for when one big PDF really ought to be several smaller ones: a scanned batch of invoices that need filing separately, a 300-page report you want to send chapter by chapter, or a combined bank statement where each month should be its own file. There are four ways to split, and a live preview colours each page by the file it will end up in, so you can see the result before you press anything.
- 1
Open your PDF
Choose or drop the file. Every page appears as a thumbnail.
- 2
Choose how to split
Custom ranges, every N pages, every page, or by bookmarks.
- 3

Several files arrive as one ZIP; a single file downloads directly.
Split PDF features

- Split every N pages into equal chunks
- Split into single pages
- Split by top-level bookmarks, one file per chapter
- Live colour-coded preview of which page goes into which file
- Several output files download together as one ZIP
Splitting a PDF without uploading: what happens to your file
The split runs entirely in your browser tab. Your PDF is not uploaded; the new files are built from it in memory and handed straight to your downloads folder.
Each output file is a fresh PDF containing copies of the chosen pages, untouched: no re-rendering, so text stays searchable and images keep their quality. Your original file is never changed.
- Custom ranges accept
3,2-6and8-end, separated by commas. Each range becomes one file, or tick Merge all ranges into one PDF to get a single file. - Every N pages makes equal chunks; the last one holds whatever is left over.
- By bookmarks uses the PDF’s top-level outline, naming each file after its chapter. It only appears useful if the PDF has bookmarks.
Ranges on a 10-page file
Type 1-3, 5, 9-end into Page ranges. The preview marks pages 1–3 as file 1, page 5 as file 2 and pages 9–10 as file 3; pages 4 and 6–8 are greyed out as skipped. Press Split and you get a ZIP holding three PDFs of 3, 1 and 2 pages. Switch to Every N pages with N = 4 instead and the same document becomes files of 4, 4 and 2 pages. If you type 11 or 5-2, the tool names the problem range and asks you to fix it rather than guessing.
Good to know
- Want just one or two pages, not a set of files? Extract pages is quicker.
- Ranges can overlap, so the same page can go into more than one output file.
- Splitting doesn’t make pages lighter. If each part still needs to be smaller, run it through Compress PDF.
- A PDF with only one page can’t be split; the tool will tell you and suggest another option.

Split PDF: frequently asked questions
Is the original file changed?
No. Splitting creates new files; your original stays exactly as it is on your device.
Can I get one PDF instead of several?
Yes. Each range normally becomes its own file, but tick Merge all ranges into one PDF and the ranges are combined, in the order you typed them.
Can I split by chapters?
If your PDF has bookmarks, choose By bookmarks and each top-level chapter becomes its own file, named after the chapter. Files without bookmarks can be split by range instead.
Does splitting reduce quality?
No. Pages are copied, not re-rendered, so text stays sharp and searchable and images are untouched.
How do I split a big PDF on my phone?
The same way as on a computer: open the file, choose a mode and tap Split. Very large files depend on the phone’s memory; if it struggles, close other tabs or split it on a computer instead.
