How to split your PDF

  1. 1

    Add the PDF you want to split.

  3. 3

    Click Split PDF and download the files (several files come as one ZIP).

Split by file size

Set a maximum size per file and the document is cut at page boundaries so that each part stays under it. A single page larger than the limit gets a file of its own; compress it if it still needs to be smaller.

Private by design

Your file is processed by your own browser, in memory. It is never uploaded, stored or seen by anyone, and the page’s security policy blocks it from sending data to other servers.

Frequently asked questions

How do I split PDF file size?

Add the PDF you want to split. Choose how to split it: every page, page ranges, chunks, by size or in half. Click Split PDF and download the files (several files come as one ZIP).

How do I split a PDF into separate files?

Add the PDF, pick a mode (custom ranges, fixed ranges, selected pages or every page) and check the preview. Click Split PDF to download the files; more than one file comes as a ZIP.

Can I save every page as its own PDF?

Can I split by specific page numbers?

Yes. In Custom ranges, set “from page” and “to page” for each range, or in Select pages type a list like 1, 4-6, 9.

Does splitting change the content?

No. Pages are copied exactly as they are, including text, links and images.

Is it safe to use with confidential documents?

Yes. The file is opened by your own browser and processed in your device’s memory. It is never uploaded, so no server, including ours, ever receives a copy. That makes it suitable for contracts, IDs, medical or bank documents.
