How to Split a PDF Into Separate Files
The short answer
To split a PDF into separate files, upload it to a splitting tool, choose where to cut (one page per file, a page range, or every second page), and download the results. Free tools handle this in a minute; on a Mac, Preview can do a basic version without any downloads.
Split a PDF online (the fast way)
- Open the free PDF tools page and pick the split tool.
- Upload the PDF. Choose your mode: one file per page, a range (like pages 1-10), or extract specific pages.
- Download — you’ll usually get a zip of separate PDFs, or one PDF if you extracted a range.
This is the right tool for real jobs: splitting a 50-page contract into chapters, pulling the signature page out of a full document, separating a scan of two pages that came in as one.
Split a PDF on a Mac with Preview
Preview doesn’t have a one-click split, but it can fake it: open the PDF, drag the page thumbnails you want into a new window (or onto the desktop — each drag-out creates its own file), then export. It works fine for pulling a few pages out; for splitting a whole document into many files, it’s tedious, and the online tool wins.
The honest part
Two things worth knowing:
- Splitting is cutting, not copying. When you split pages out, the new file contains those pages only — but the original stays untouched unless you replace it. Keep both until you’re sure the split is right.
- Page numbers in the document don’t reset. If a report says “page 12 of 40” on its pages, splitting out pages 12-20 keeps that label — the file is now 9 pages that still say “of 40”. Annoying but harmless; just know it’s coming.
And one workflow note: splitting is the reverse of combining PDFs. People usually do one or the other to organize a document — pull out what belongs elsewhere, merge what belongs together. If you’re doing both on the same file, stop and ask why the file is such a mess in the first place.
