Frequently asked questions

Can I split by bookmarks without paying?

Yes. The tool is free and unlimited, with no uploads involved.

Where is the splitting performed?

On your device. The outline is read and the parts are created locally in your browser; the PDF is never sent anywhere.

Do I need to install anything to use it?

No. It runs entirely in the browser on any platform, with nothing to download.

How are the cut points decided?

Every top-level bookmark in the PDF outline starts a new file automatically. Each resulting PDF is named after its bookmark, so chapters keep meaningful names.

What if my PDF has no bookmarks?

This tool relies on the outline, so a PDF without bookmarks cannot be split this way. Use the regular split tool or split by text instead.
