Split a large PDF into smaller files: extract a chapter, turn every page into its own file, or split every fixed number of pages. Page thumbnails help you choose precisely.
How to use it
- Choose a PDF file.
- Pick a mode: custom ranges, fixed size, every page, or extract the pages you click.
- Click “Split PDF” and download the files (as a ZIP when there are several).
Features
- Four split modes for every need.
- Easy range syntax like 1-3, 5, 8-.
- Option to merge selected ranges into one file.
- Original page quality preserved.
Practical examples
- Send only what's needed: from a 30-page contract, an office may only want the signature page and an annex — type a range like 1, 29-30.
- Separate a batch scan: scanned ten certificates into one file? Choose “every page” to get ten separate files.
- Get under an upload limit: split the file every fixed number of pages and upload the parts one by one.
- Pull one chapter out of a long handout to read on your phone.
Common mistakes
- Typing ranges with spaces or an Arabic comma “،” — use a plain comma and a hyphen.
- Forgetting that numbering follows the page order in the file, not the numbers printed on the pages.
- Splitting when you only need to delete a few pages — Organize PDF is quicker for that.
Privacy and security
“Split PDF” runs entirely in your browser using trusted open-source libraries. Your files are never uploaded to a server and no copy is kept, so your documents stay private. It is free and needs no sign-up.
Tip: To delete or reorder pages instead, use “Organize PDF”.
