What does this Split PDF tool do?

It takes one PDF and divides it into several smaller PDFs. You decide how: one file per page, equal chunks of a fixed size, or custom page ranges that you type in. Each resulting file is a complete, standalone PDF whose pages are copied from the original without any re-rendering, so nothing loses quality along the way.

How to split a PDF

  • Add your PDF using the upload box — the tool reads its page count on your device.
  • Pick a split mode and, if needed, enter the chunk size or your page ranges.
  • Click "Split PDF" and download the parts individually, or grab everything at once as a ZIP archive.

The three split modes

Every page: produces one PDF per page — useful when a scanner has bundled separate documents into a single file. Chunks: cuts the document into equal slices, such as every 10 pages, which keeps large reports manageable. Custom ranges: type ranges like 1-3, 4-9, 10 and each range becomes its own file — ideal for pulling apart contracts, chapters or exhibits that you know by page number.

Everything happens on your device

This splitter loads a PDF library into your browser tab and does all the cutting locally. The document is never transmitted, so there is no upload wait, no server queue, and no privacy question about who might see the file. That matters for exactly the documents people split most often: contracts, bank statements, medical records and scans that bundle several private documents together.

Tips

  • The ZIP download is the fastest way to save many parts at once.
  • Ranges can be typed in any order and may skip pages entirely — pages you don't mention are simply left out.
  • Password-protected PDFs need to be unlocked first; you can do that with the Unlock PDF tool on this site.
  • If you only need one range as a single file, the Extract PDF Pages tool does that with a visual page picker.

Frequently asked questions

Is my PDF uploaded when I split it?

No. The file is opened and split by JavaScript running in your browser. It never leaves your device, and closing the tab removes every trace of it.

How are the output files named?

Splitting every page produces files like report-page-3.pdf, while chunk and range splits produce report-part-1.pdf, report-part-2.pdf and so on, based on the original file name.

Does splitting reduce quality or change formatting?

No. Pages are copied as complete objects — fonts, images and layout are untouched. Each part is a normal PDF you can open, print or share anywhere.

Can I split a password-protected PDF?

Not while it's locked. Remove the password first with the Unlock PDF tool (you'll need to know the password), then split the unlocked file.

What's the maximum size or page count?

There's no hard limit built into the tool. Since everything runs locally, the practical ceiling is your device's memory — hundreds of pages are normally no problem.
