About PDF Splitter

PDF Splitter splits a single PDF into multiple files. Pick "Even split" or "Page range" depending on the goal.

In Even split, asking to divide a 10-page PDF into 3 produces a roughly even 4 / 3 / 3 distribution. In Page range mode, write multiple ranges with commas — for example "1-3, 5, 7-10". Output files can be downloaded together as a ZIP, which makes chapter or section splits a one-click job.

All PDFs are split entirely in your browser — nothing is uploaded to a server. Confidential or personally-identifying documents stay local. Runs entirely in your browser.

How to use

  1. Drop a PDF into the dropzone, or click to pick one.
  2. Choose "Even split" or "Page range" mode.
  3. Enter the split count for Even split, or comma-separated ranges (e.g., 1-3, 5, 7-10) for Page range.
  4. The preview shows the page range of each resulting file.
  5. Click each file’s "Download", or use "Download as ZIP" to grab everything at once.

Use cases

  • Splitting a scanned bundle of documents into per-chapter files for distribution.
  • Pulling just the relevant pages out of a long set of meeting notes or a report to share.
  • Educators and researchers excerpting parts of papers or textbooks for citation or distribution.
  • Presenters splitting a deck by speaker.
  • Individuals breaking an ebook PDF by chapter for per-device reading.

Notes

  • Maximum 100 MB per file.
  • Password-protected PDFs cannot be split — remove the password first, then load.
  • Page range mode rejects duplicate pages across ranges (overlap is an error).
  • Page numbers are 1-based; zero, negatives, or numbers beyond the page count are errors.
  • When Even split cannot divide evenly, leftover pages are assigned to earlier parts.

FAQ

Are PDFs uploaded to a server?
No. Splitting happens entirely in your browser, so confidential or personally-identifying documents are safe to use here.
How do I write page ranges?
List pages or ranges separated by commas. For example, "1-3, 5, 7-10" splits into three files containing pages 1–3, page 5, and pages 7–10. Half-width hyphen (-) is a range, comma (,) is a separator.
Can I split an encrypted PDF?
Password-protected PDFs cannot be split. Export an unprotected copy first, then bring it back in.
How does Even split handle leftover pages?
Leftovers are assigned to earlier parts. For example, a 10-page PDF split into 3 becomes 4 / 3 / 3 pages.
Can I download the results together?
When several files are produced, a "Download as ZIP" button appears, packaging every part into one ZIP in a single click.
