Frequently Asked Questions
Is it safe to split confidential reports?
Yes! Pdfguin runs entirely in your browser. Your confidential files are processed locally and are never uploaded to any remote server.
What if my PDF doesn't have bookmarks?
This tool requires internal bookmarks (outlines) to determine chapter breaks. If your PDF has no bookmarks, we recommend using our "Extract Pages" tool instead.
