About this tool
Split by chapter-sized chunks or exact ranges. Every output document preserves original page fidelity because pages are copied byte-for-byte, not re-rendered.
How to use it
- Add the PDF you want to divide.
- Choose fixed-size parts or define custom ranges.
- Split and preview each resulting document.
- Download individually or all at once as a ZIP.
Frequently asked questions
How do I split every 2 pages?
Choose "Fixed size" mode, enter 2, and the tool produces one document per pair of pages.
Can I split specific ranges like 1-3 and 7?
Yes — use "Custom ranges" and type ranges separated by commas, e.g. 1-3, 4-6, 7. Each range becomes its own PDF.
Does splitting upload my file?
No. Splitting happens entirely on your device — the file never leaves your browser.
