ABOUT THIS TOOL

What is Split PDF?

A large PDF can be easier to share when each section becomes its own file. Split PDF creates separate documents from a single PDF, with either one page per file or comma-separated page ranges. For sensitive records, make sure each exported file contains only the pages its recipient should see.

How to use Split PDF

  1. Choose a PDF from your computer or phone.
  2. Leave the ranges field blank to export every page separately, or enter ranges such as 1-2,3-5,6.
  3. Run Split PDF to download a ZIP archive of the resulting PDFs.

When is this useful?

For a 12-page report, enter 1-2,3-10,11-12 to make introduction, main report, and appendix files.

Tips for better results

  • Ranges count from page 1, not page 0.
  • A ZIP download is handy when you need many separate PDFs.
  • Look at the page count before choosing ranges to avoid out-of-range errors.

Important: Keep your original file and review the downloaded output. Not every interactive PDF form, digital signature, annotation, or specialized PDF object is guaranteed to be preserved.

COMMON QUESTIONS

Frequently asked questions

Can I split at different lengths?

Yes. Each comma-separated range creates a separate PDF; 1-3,4-4,5-8 makes three files.

Is the original changed?

No. Your source stays on your device as it was.

What if there is only one page?

You can still export the first page, though splitting a single-page PDF is rarely useful.
