Split PDF by Bookmark — frequently asked questions

My PDF has no bookmarks — what happens?+

The tool tells you and you should use Split PDF with page ranges instead.

What about nested bookmarks?+

Only the top-level bookmarks are used as split points.

Laddar ni upp mina filer till en server?+

Nej — alla verktyg här bearbetar dina filer helt på din enhet, och inget laddas upp till en server. Det enda undantaget är AI-verktygen, som skickar den extraherade texten (inte filen) till Claude för att göra sitt jobb.

Finns det en filstorleksgräns?+

Vi sätter ingen konstgjord gräns, men eftersom bearbetningen sker i din webbläsare begränsas mycket stora filer (500+ MB eller 1 000+ sidor) av din enhets minne, inte av oss.
