Frequently Asked Questions

Split PDF FAQs

Answers to common technical questions and format capabilities.

How do I enter page ranges to extract?

Enter page numbers and ranges separated by commas. For example, '1-3, 5, 8-10' extracts pages 1, 2, 3, 5, 8, 9, and 10 into the new PDF.

What happens if I list the same page number twice?

Our parser retains the first occurrence of each page in the user-specified sequence and automatically ignores subsequent duplicate mentions.

Can I enter ranges in reverse order (e.g. 5-2)?

No. Ranges must be ascending (e.g. 2-5). If you want to reverse the order of specific pages, list them individually separated by commas (e.g. 5, 4, 3, 2).
