Split PDF by File Size — frequently asked questions

Does it compress the pages?+

No — it only groups pages. To make the file itself smaller, use Compress PDF or Compress to Target Size first.

What if one page is bigger than the limit?+

That page becomes its own file, and the tool notes it couldn't get under the limit for that one.

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.
