Frequently Asked Questions
How do I split a PDF into single pages?
Choose 'Fixed-size parts' with 1 page per file. You get one PDF per page, all together in a ZIP, named after your file with the page number: report-p01.pdf, report-p02.pdf and so on.
How do I write page ranges?
Separate files with commas and use a hyphen for a range: '1-5, 8, 11-14' makes three files. Ranges can be in any order. A page number outside the document is reported rather than skipped.
Will the parts keep the original formatting?
Yes. Pages are copied as they are, with fonts, images and links intact. Each part contains only the pages it needs, so the parts are smaller than the original.
Can I split a password-protected PDF?
Not directly. A password-protected PDF is encrypted, and the tool tells you so instead of producing a broken file. Open it in your PDF viewer with the password, use Print → Save as PDF to make an unprotected copy, and use that.
Are my files uploaded?
No. Everything happens in your browser; the file is never uploaded to a server, so it stays on your device.
About PDF Splitter
The PDF Splitter breaks one PDF into several. Split it into fixed-size chunks (every page, every 2 pages, every 10) or into custom ranges such as a chapter per file.
All the parts download together as a ZIP, with names that keep their order when sorted: the original file name plus zero-padded page numbers. You can also download any single part from the list.
Splitting copies each part's pages into a new document, so a part contains only what its pages use. It runs in your browser with pdf-lib and nothing is uploaded.
