How to split a PDF
- Add your PDF. Drag it onto the box or click to browse. The tool reads it on your device and shows the total page count.
- Pick a split mode. Choose Each page as a separate PDF to explode every page into its own file, or Custom ranges to group pages your way.
- Enter ranges (custom mode). Type comma-separated groups such as
1-3, 4-6, 7. Each group becomes one output PDF. - Split and download. Press Split & download ZIP. Every part is generated and bundled into
split.zip, which downloads instantly.
The two split modes explained
Each page as a separate PDF is the simplest option: a 10-page document becomes ten one-page PDFs, named in order so they stay sorted. This is perfect when every page is a standalone item — invoices, certificates, tickets or scanned forms. Custom ranges gives you precise control. A range like5-7 keeps pages 5, 6 and 7 together in one file, while a lone number like 7 pulls a single page out on its own. You can mix the two freely — 1-3, 4-6, 7 yields three PDFs in a single run. Ranges may overlap or repeat pages if you want copies in more than one output; the tool simply builds each group exactly as written.
When splitting a PDF is handy
A scanned stack often holds several unrelated documents — split it so each receipt, contract or statement is its own file. Teachers can break a packet into per-student worksheets; an accountant can separate a bundle of invoices for filing. If you only need a chapter from a long report, pull it into its own PDF instead of sending the whole book. Because every result is a standard PDF, the parts open anywhere and print exactly as expected, and the ZIP keeps the download to a single click.
Is it private?
Yes. Unlike many online PDF splitters that upload your file to a server, this tool does all the workon your device using the self-hosted pdf-lib and JSZip libraries. Your PDF and every split file are never uploaded or stored — which matters for contracts, statements, medical records and other sensitive documents. Once the page has loaded it even works offline. Passwordless PDFs work best; an encrypted file may fail to open.
Frequently asked questions
Does it upload my PDF?
No — the file is split in your browser and zipped locally; nothing leaves your device.
How do I write the ranges?
Use comma-separated groups like 1-3, 4-6, 7. Each group becomes one PDF, dashes include both ends, and page numbers start at 1.
Why is the download a ZIP?
Splitting produces several PDFs, so they are bundled into one split.zip to save you downloading each file by hand.
What if I enter a page that does not exist?
The tool checks your ranges against the total page count and shows an error instead of producing a broken file.
