What is Split PDF?

Split PDF takes one document and turns it into several smaller ones. You can pull out exactly the pages you need – a single chapter, the signature page, an annex – or cut a long file into equal parts, for example one PDF per page or one per ten pages. The pages are copied as they are, so text, images and links keep their original quality.

Private by design

The document is processed entirely in your browser with the open-source pdf-lib library, running in a background worker. Your file is never uploaded to a server and nothing is kept after you close the page. When the split produces several files, they are packed into a ZIP archive that is also built on your device.

How to split a PDF

  1. Drop your PDF onto the drop zone or click Choose file. The tool shows how many pages it has.
  2. Choose a method:
    • By page ranges: type ranges separated by commas, such as 1-3, 5, 8-. Each range becomes its own file. 8- means “from page 8 to the end” and -4 means “from the start to page 4”. Tick the option to join all ranges into a single file when you only want to extract some pages.
    • Every N pages: cut the document into files of the same size. Use 1 to get one file per page.
  3. Click Split PDF and download the result: a PDF if there is a single output, or a ZIP otherwise.

The output files are named after the original document and the pages they contain, such as report-p1-3.pdf, so they stay easy to identify.

Common uses

  • Send only the relevant pages of a long contract or report instead of the whole document.
  • Separate a batch of scanned invoices into one file per invoice.
  • Break a large manual into chapters that are easier to share by e-mail.
  • Extract the pages you need to sign, then put them back with Merge PDF.

Frequently asked questions

Can I extract pages that are not consecutive?

Yes. Write them as separate ranges, for example 2, 7, 11-12, and tick “Put all the ranges into a single file”. The result contains those pages in the order you typed them.

What happens with password-protected files?

Encrypted PDFs cannot be split until the password is removed. If you know it, use Unlock PDF first.

Is there a size limit?

Files can be up to 100 MB and 500 pages. Everything runs on your device, so speed depends on your computer rather than on an internet connection.
