Split a PDF into Separate Files
Break one PDF into several smaller documents. Choose single pages, equal chunks, or type the exact ranges you need — each range becomes its own PDF.
How to split a PDF
- Choose the PDF you want to split. The page count appears once it has been read.
- Pick a mode: every page, every N pages, or custom ranges such as 1-3, 5, 8-10.
- Select Split PDF and wait for the parts to be created.
- Download a single part, or all parts together as a ZIP file.
Supported formats
- Input
- Output
- PDF, ZIP of PDFs
- Maximum size
- 200 MB per file (limited by your device's memory)
Writing page ranges
Separate ranges with commas: "1-3, 5, 8-10" produces three files. An open-ended range such as "9-" runs to the last page, and "last" can be used as a page number. Ranges may overlap — each one is exported independently. If you want several ranges combined into one PDF instead of separate files, use the PDF Page Extractor; to stitch files back together afterwards, use the PDF Merger.
Benefits
- Three splitting modes cover the common cases without any page-by-page clicking.
- Range input is validated as you type, with clear messages for pages that don't exist.
- Pages are copied losslessly; text and links inside the page remain intact.
Limitations
- Encrypted PDFs must be unlocked in a PDF reader before they can be split.
- Fonts and images shared between pages are copied into every part, so the parts together can be larger than the original.
- Bookmarks and form fields from the original are not copied into the parts.
Privacy and security
Splitting is done by pdf-lib in a Web Worker inside your browser. The original PDF and the generated parts stay in memory on your device and are never uploaded; the ZIP is also built locally.

Frequently asked questions
Can I split a PDF into files of 10 pages each?
Yes. Choose "Every N pages" and enter 10. A 95-page document becomes ten files: nine with 10 pages and a last one with 5.
Why do I get a ZIP instead of separate downloads?
Browsers often block many simultaneous downloads, so multiple parts are bundled into one ZIP. Each part also has its own Save button in the result list, and a single result is offered directly as a PDF.
What happens if my ranges overlap?
Each range is exported as written, so overlapping pages simply appear in more than one output file.
