Splitting takes one PDF and produces several. That is what you need when a scanner has put twenty documents into a single file, when only a few pages of a long report are relevant, or when a portal wants each certificate uploaded separately.
Your file never leaves your device. The PDF is read by your browser and edited in memory by a JavaScript library served from this site. Nothing is uploaded, nothing is stored, and closing the tab discards everything. You can verify this by opening your browser's network tab while you use the tool.

What the Split PDF does
Three ways of splitting cover almost every case. Splitting every page gives one file per page — useful for a batch scan of separate documents. Fixed chunks give equal groups, which suits double-sided scans or fixed-length forms. Custom ranges let you say exactly which pages belong together.
Because splitting produces multiple files, they are packaged into a single ZIP for download. Each file inside is named after the source document and the pages it contains, so nothing is ambiguous once extracted.
How to use this tool
- Select the PDF you want to split.
- Choose how to split it: every page, fixed chunks of a size you set, or custom ranges.
- For custom ranges, type them comma-separated —
1-3, 4-6, 7creates three files. - Press Split PDF and wait while each output file is generated.
- Download the ZIP and extract it. Each file is named with the pages it contains.
How the split is decided
Every page: one output file per page
20 pages → 20 files
Fixed chunks: groups of N consecutive pages
20 pages, chunk 3 → 7 files (last has 2 pages)
Custom ranges: one file per comma-separated range
"1-3, 8, 12-15" → 3 files of 3, 1 and 4 pages
Pages are copied unchanged into each new document, then all
the outputs are packaged into a single ZIP.
Worked example
Example: a 12-page scanned bundle
| Ranges entered | 1-2, 3-7, 8-12 |
| File 1 | pages 1–2 (covering letter) |
| File 2 | pages 3–7 (application form) |
| File 3 | pages 8–12 (annexures) |
The ZIP contains three PDFs named after the ranges, so you can upload each to the field that expects it without opening them to check.
What your result means
The file count in the result tells you whether the split did what you intended. Three ranges should produce three files.
Pages not covered by any range are discarded in ranges mode. If you want everything, make sure the ranges cover the whole document.
The ZIP extracts with standard tools on every phone and computer. On Android and iOS, tap the downloaded file to extract it.
Important considerations
- Page numbers here are the positions in the PDF, which may differ from numbers printed on the pages themselves — a report with roman-numbered front matter is the usual case.
- Ranges may overlap if you want the same page in two outputs. Nothing prevents it, and it is occasionally useful.
- To pull out a few pages as a single file rather than several, use the extract pages tool instead.
- Splitting does not reduce total size — the outputs together are roughly the size of the input, since each carries the resources its pages need.
- Very large documents produce many files. Splitting a 500-page PDF page by page creates 500 files, which is slow to ZIP and awkward to handle.
Limitations of this tool
- Everything runs in your device's memory, so very large documents — several hundred high-resolution scanned pages — can be slow or exhaust available memory. The tool reports a clear error rather than crashing silently.
- Password-protected PDFs cannot be opened. Remove the password in a PDF reader first and save an unprotected copy.
- Damaged or partially downloaded PDFs cannot be parsed. If a file fails, try re-downloading it from the original source.
- Bookmarks and interactive form fields are not carried into the split files.
- Splitting every page of a very long document is memory-intensive; chunked splitting is more reliable above about 200 pages.
Frequently asked questions
How do I split a PDF into separate pages?
Choose "Every page separately". A 20-page PDF produces 20 single-page files, delivered as one ZIP.
Why is the download a ZIP file?
Because splitting produces several files and a browser can only download one thing at a time. The ZIP keeps them together and extracts with the built-in tools on any phone or computer.
Can I extract just pages 5 to 10 as one file?
Yes — use custom ranges and enter
5-10, which produces a single file. The extract pages tool is designed for exactly that and is slightly quicker.Do the split files keep the original quality?
Yes. Pages are copied across without re-rendering, so text stays selectable and images are untouched.
