UUID Generator — frequently asked questions
v4 or v7?+
v4 is fully random. v7 embeds a timestamp so the IDs sort chronologically — better as database keys.
Are these guaranteed unique?+
v4 has ~5.3×10^36 possibilities, so collisions are effectively impossible in practice.
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.
