How to Split PDF Files: 4 Free Ways on Windows and Mac
Splitting a PDF sounds like one job, but it's really three, and knowing which one you have makes it quick:
- Extract a range — you want pages 3–8 of a report as their own file.
- Break into equal parts — a 40-page scan should become ten 4-page documents.
- Separate a batch — someone scanned twelve receipts into one PDF and you need twelve files.
Most "split PDF" sites upload your document to handle all three. As with any file that carries something personal — contracts, statements, records — that means the whole thing goes to a server so you can pull out a piece of it. It doesn't have to work that way.
The quick answer: you may already have a splitter
If you need one range of pages as its own file, the software already on your computer can do it. Each of these saves one range per pass:
- Chrome or Edge, any computer. Open the PDF in the browser, press Ctrl+P (Cmd+P on a Mac), set the destination to Save as PDF, choose Pages → Custom and type the range, e.g.
3-8. Save. That file holds only those pages. - Windows, any PDF viewer. Print, pick the Microsoft Print to PDF printer, enter the page range, and save the new file.
- Mac, Preview. Open the PDF, turn on View → Thumbnails, select the pages you want (Cmd-click for several), and drag them onto the desktop. Preview writes them out as a new PDF.
- Adobe Acrobat. Organize Pages → Split does it, but splitting is a paid Acrobat Pro feature; the free Reader cannot.
Where these run out: every range is a separate pass, and none of them can cut a 40-page file into ten 4-page parts or split a batch scan at its blank pages. That is what the tool below is for.
Splitting happens on your device
Splitting a PDF is just copying selected pages into new files. It's light work — no rendering, no conversion, barely any computation. Docexp's Split a PDF tool does it right in your browser with an open-source PDF library: your file is read into the page, the pages you asked for are written into new PDFs, and those download to your disk. Nothing is uploaded, because there's no server in the loop to upload to.
The three ways to split
The tool covers all three jobs above:
- By custom range — type the pages or ranges you want (e.g.
3-8, or1, 4, 9-11) to pull exactly those into a new PDF. This is the one to use for "just give me the chapter." - By fixed page count — split every N pages, turning one long file into evenly sized pieces.
- By blank separator pages — auto-detect the blank pages a scanner inserts between documents and split there. This is what turns one "batch scan" back into the individual files it should have been.
Open Split a PDF, add your file, pick the method, and download the parts. No page cap, no watermark, no sign-up.
Split, or something else?
"Split" is often the wrong word for what people actually need:
- If you just want to drop a few pages — the blank last page, a duplicate — you don't need to split at all. Use Delete pages and keep one clean file.
- If the pages are all there but out of order from a scan, fix that with Reorder pages instead of splitting and rebuilding.
- And if you split too far and need to recombine some pieces, Merge PDFs puts them back together.
Check it yourself
Any site can claim "your file stays on your device." To confirm it on this tool or any other: open the browser's Network tab (F12), run the split, and watch for an upload. On a genuinely client-side tool there isn't one — and it'll keep working even if you disconnect from the internet after the page loads. The safest document is the one that never left in the first place.
