How to split a PDF
- Drop or select a PDF file.
- Choose All pages to get each page separately, or Custom ranges for specific parts.
- For custom ranges, enter ranges like
1-3, 5, 7-9. - Click Split PDF - a single page downloads directly; multiple pages come as a ZIP.
The range syntax, explained
Custom mode accepts ranges the way you would say them: 1-3, 5, 7-9 extracts pages one through three, page five, and seven through nine, in that order, into a new PDF. This is the fast way to pull one chapter out of a report, extract just the signature page of a contract, or remove a blank page a scanner inserted (select every page except it). "All pages" mode instead explodes the document into individual single-page files - one PDF per page - which is what you want when each page is genuinely a separate document, like a batch of scanned receipts.
When splitting beats sending the whole file
Three common triggers: an upload limit the full document cannot fit (send the relevant pages only), privacy (share page 4 of a statement without pages 1-3 of personal detail), and organization (a 200-page scan session split back into its constituent documents). Splitting is also the standard prep step before re-merging pages in a new order with the Merge PDF tool - split, then merge in the order you actually want.
Limitations to know
Splitting copies pages exactly - it cannot split one page in half or separate content that shares a page. Encrypted PDFs must be unlocked first, and page-level extras like bookmarks pointing at removed pages will no longer resolve in the output.
