Know the boundary

What this tool does—and what it does not.

Page numbers start at 1. Encrypted or damaged documents may need to be repaired or unlocked before they can be split. Only removing a few unwanted pages? See the delete-pages examples instead.

A practical PDF splitting guide

One PDF in. The right files out.

Separate a report into sections, create one PDF per page, or divide a document into equal page groups. Choose the output you need before entering page numbers: Split creates several files; Extract keeps a selection together in one file.

Split an eight-page PDF, three ways.

Open Split PDF, choose your PDF in the workspace, then select range mode or fixed-page mode in the Split panel. Count page positions from 1, including covers and contents pages. Printed page labels can differ from positions in the file.

Choose your own sections

In range mode, enter 1-3,4-6,7-8. Expect three PDFs: original pages 1–3, 4–6 and 7–8. Each comma-separated selection becomes its own file.

Split every three pages

In fixed-page mode, enter 3. An eight-page PDF produces three PDFs with 3, 3 and 2 pages. The final file contains the remaining pages.

Create one file per page

In fixed-page mode, enter 1. An eight-page PDF produces eight one-page PDFs. In range mode, entering 1 instead selects only the first page.

Use a standard hyphen - when typing a range, not a long dash. Keep every page number within the document and put the lower number first. To split by chapter, enter the chapter's actual page range; this tool does not detect chapter headings automatically.

You do not need to include every page. For example, range mode with 2,5-7 creates two PDFs: one containing page 2 and one containing pages 5–7. Pages outside those selections are not included in these outputs; keep your original document.

Check the files, not just the completion message.

  1. Count the downloads. Split triggers a separate PDF download for each group. If fewer files appear than expected, check the browser's download list and any multiple-download prompt for PDFbuff.
  2. Open every result. Compare its page count and first and last pages with your intended ranges. For the first example, expect page counts of 3, 3 and 2.
  3. Review special content. Check links, bookmarks, forms and existing signatures before sharing edited files. Do not assume these remain intact after pages are copied.
  4. Keep the original. Give outputs distinct filenames if prompted. A triggered download does not by itself prove that every file was saved correctly.

Splitting by page count is not splitting by file size: three pages of scans can be larger than many pages of text. There is no target-MB mode here. If an output needs to be smaller, review the tradeoffs of PDF compression separately. Encrypted or damaged PDFs may not open or export; Split is not a password-removal or repair service.

Need one file rather than several?

  • Split when each selected range should become a separate PDF, or when you need a fixed number of pages per file.
  • Extract PDF Pages when selected pages should stay together. Entering 2,5-7 there produces one four-page PDF, not two separate files. See the extraction guide for page-order and duplicate-selection checks.
  • Delete PDF Pages when most of the original should stay and you only need to remove a few unwanted pages.

Split is free without an account for files within 20 MB and 100 pages. Document processing runs locally in your browser. Larger files require eligible Pro access and sufficient device capacity; see the current beta rules and file limits. Paid checkout is currently disabled.

Split PDF FAQ

Before you start.

Does each comma-separated range become a separate PDF?

Yes. For a ten-page PDF, 1-3,5,8-10 creates three files: pages 1-3, page 5, and pages 8-10. To keep those pages together in one file, use Extract PDF Pages instead.

Can I split every page into a separate PDF?

Yes. Choose the fixed-page mode and set one page per file.

Will splitting change page quality?

Pages are copied into new PDF files without intentional rasterization.

Where are the split files processed?

Inside your browser on the device you are using.
