Split PDF
Open a PDF, see thumbnail previews of every page, and split into one or more output files. Pick ranges like '1-3, 7, 10-12', extract every page separately, or save the selected subset as a new PDF. All in your browser with pdf-lib.
Splitting happens entirely in your browser. Your PDF never leaves your device.
How to use this split pdf
- Drop or pick a PDF file. Page thumbnails appear.
- Choose a mode: 'Ranges' (e.g. 1-3, 5, 8-10), 'Every page' or 'Selected pages'.
- Click pages to select them, or type a range expression.
- Click Split & download — get one file per range, or a single new PDF with just the chosen pages.
Frequently asked questions
Why is my single-page split file almost as large as the original?
PDFs share resources (fonts, images, color profiles) across pages. When you split out one page, pdf-lib has to copy every resource that page references — so a 50 MB PDF where each page uses the same embedded photo set produces 1-page files that are still multi-megabyte. To shrink them, run each split file through the PDF compressor afterwards.
What range syntax can I use?
Comma-separated single pages and ranges, like '1, 3-5, 8'. Spaces are ignored. Use 'end' or 'N' to mean the last page (e.g. '12-end').
Can I split a password-protected PDF?
Not currently. Remove the password first in a desktop PDF reader, then split the unprotected file.
What happens to bookmarks and metadata?
Each output PDF inherits a fresh metadata block. Page content is preserved; bookmarks tied to removed pages are dropped.
