FAQ
Frequently asked questions
How does the split interval work?
Enter N, and the tool creates a new PDF every N pages. A 10-page PDF split every 3 pages yields parts of 3, 3, 3, and 1 pages.
Can I split by custom page ranges?
This version splits uniformly every N pages. For extracting specific pages, use the Extract Pages tool instead.
Are the split parts valid PDFs?
Yes. Each part is a complete, valid PDF that opens in any viewer.
Is my original file modified?
No. The original file is read only; the split parts are new files generated in your browser.
