Split a PDF or extract pages
Pull out the pages you need, or break a document into single pages. Done on your device.
Done
Open the network tab. It stays empty.
Add files and run the tool to see every request this tab makes.
Your files are processed on this device and never sent to a server. Reload the page to clear everything from memory.
How it works
- Drop a PDF onto the page.
- Choose a mode: extract a range like 1-3, 7, 10-12 into one file, split every page into its own file, or split every N pages.
- Download the result, as one PDF or a zip of PDFs.
In your browser, not on a server
pdf.js, the PDF renderer inside Firefox, draws page thumbnails so you can see what you are extracting. pdf-lib then builds the new PDFs from the pages you chose, copying them exactly rather than rasterising them. All of it runs in a web worker inside your tab.
Compared with upload-based tools: Online splitters make you upload the whole document to extract two pages from it. Here the document stays on your disk and only the pages you asked for are written out.
Verify it yourself. Load this page, turn off Wi-Fi or switch to airplane mode, and run the tool. Or open your browser's developer tools (F12, or Cmd-Option-I on a Mac), pick the Network tab, and watch it while you convert. The panel above does the same count for you.
Questions
How do I write a page range?
Use commas and dashes: "1-3, 7, 10-12" keeps pages 1, 2, 3, 7, 10, 11 and 12 in that order. You can repeat pages or list them out of order to reorder them.
Can I delete pages from a PDF?
Yes. Enter a range that lists every page except the ones you want to remove, and download the result.
Is my document uploaded?
No. Splitting happens in your browser with pdf-lib. Nothing is sent anywhere.
