Ways to split

  • Chosen pages: e.g. 1-3, 7, 10- makes one file with those pages (10- means from page 10 to the end).
  • Every page separately: as many files as pages.
  • Every N pages: e.g. a scan of 20 two-page invoices split every 2.
  • By ranges: 1-3; 4-8; 9- gives three files.

Common questions

Are my files uploaded anywhere?

No. The file is read and processed in your browser, and the result is saved straight to your disk. You can check: once the page is open, disconnect from the internet and the tool still works.

Does page quality change?

No. Pages are copied without recompression, so text and images stay exactly as in the original.

What about password-protected files?

Encrypted files can’t be processed here. Open the file in your browser or PDF reader, choose Print → Save as PDF, and use the saved copy.
