## Overview (en)

Split PDF breaks one PDF into separate files, either one file per page or one file per page group you define. Groups are written as ranges separated by semicolons, such as 1-2;3-4, and every part is packed into a single ZIP download named part-1.pdf, part-2.pdf and so on.

## Questions (en)

### How do I split a PDF into custom page groups?

Type the groups separated by semicolons, for example 1-3;4;5-8. Each group becomes its own PDF inside the ZIP, and within a group you can combine commas and ranges such as 1,3-5.

### How do I split every page into its own PDF?

Leave the page groups box blank. The tool then creates one single-page PDF for every page of the document and bundles them in split-pdf.zip, numbered in page order.

### Why do I get an error about page ranges when splitting?

Ranges must run from a smaller to a larger page, so 5-2 is rejected, and every page number must exist in the document. Rewrite the range as 2-5 or check the page count.
