Compress PDF to 100KB — frequently asked questions
Will 100 KB always be possible?+
Not always. A short, mostly-text PDF gets there easily. A long, image-heavy or scanned document may not fit without unreadable quality loss — the tool tells you honestly if it couldn't hit the target.
Will the text still be readable?+
Yes — text stays selectable and sharp far longer than images do, since the compression works by re-rendering and shrinking page images, not by degrading text.
Why 100 KB specifically?+
It's a common hard limit on government portals, exam boards, and some job application forms. If your form allows more, try Compress PDF to 500 KB or 1 MB for a better-looking result.
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.
