Split PDF
Split a PDF by custom ranges, fixed intervals, selected pages or file size.
How to use Split PDF
- Add the PDF you want to break apart.
- Pick a mode: custom ranges, fixed-size chunks, individual page extraction, or split by file size.
- Enter your ranges or selection — the tool validates them against the real page count before running.
- Press Split, then download each part individually or take the whole set as a ZIP.
How Split PDF works
Split PDF gives you three ways to break a document apart. Use custom ranges when you know exactly which sections you want, such as 1-3, 4-8, 10-12. Use fixed ranges to chop a long document into equal chunks — every 5 pages, for example.
Extract pages mode is for cherry-picking: type a selection like 1,3,5-9,12, or pick all, odd or even pages. You can return them as one combined PDF or as one file per page.
Split by size is useful when something downstream imposes a limit, like an email attachment cap. Pages are added to each part until the next one would push it over your limit.
When a split produces several files, download them individually or grab everything at once as a ZIP.
Frequently asked questions
Are my files uploaded to a server?
No. This tool runs entirely inside your browser — the file is read from disk by the page and never transmitted. It keeps working even if you disconnect after the page has loaded.
What page range syntax is supported?
Commas separate entries and hyphens make ranges, so 1,3,5-9,12 means page 1, page 3, pages 5 through 9, and page 12. Invalid input — backwards ranges, page 0, or pages past the end of the document — is rejected with an explanation before anything is processed.
Can I get one PDF instead of many?
Yes. Both the range and page modes have a merge option that combines everything you selected into a single document instead of separate files.
What happens if one page is bigger than my size limit?
A single page cannot be divided further, so it is written out on its own and the tool tells you how many pages exceeded the limit. It never silently produces a file over your maximum without saying so.
Is quality affected by splitting?
No. Pages are copied into the new documents unchanged, so text, fonts and images are identical to the source.
