How it works

  1. Choose your PDF files.
  2. Set the options, then select “Split PDF”.
  3. Download the result directly from your browser, with batches packaged as a ZIP.

What this tool does

Split by custom ranges such as 1-3 and 5, make one PDF per page, or create fixed-size chunks. Multiple results are packaged into a ZIP download.

Before you start

Page numbers start at 1. Invalid or overlapping ranges should be corrected before processing, and password-protected PDFs are not supported.

Private by design

The file is read and processed by this page on your device. It is never uploaded to FormatOtter or handed to a third-party conversion service. Large documents may take a moment because your browser is doing the actual work.
