About this tool
Sometimes you need just a few pages out of a larger PDF, or need to break one document into several smaller ones. This tool splits a PDF by page ranges you define, producing one downloadable file per range, using pdf-lib entirely in your browser.
How to use it
- 1Upload a PDF — the tool detects its total page count.
- 2Enter comma-separated ranges, e.g. 1-3, 4-6, 7-9.
- 3Click "Split PDF" to generate one file per range.
- 4Download each resulting file.
Common mistakes to avoid
- Specifying a page range that exceeds the document's actual page count.
- Forgetting that page numbers are 1-indexed, matching what you see in a PDF viewer.
Use cases
- Separating chapters or sections of a large report into individual files.
- Extracting a single invoice or form from a multi-document scan.
Frequently asked questions
Is my PDF uploaded anywhere?
No. Splitting happens entirely in your browser using pdf-lib — your file never leaves your device.
Can I split into more than two files at once?
Yes. Enter as many comma-separated ranges as you like, and you'll get one output file per range.
