WAV to MP3 — vanliga frågor

Which bitrate should I pick?+

192 kbps is a good default. Use 256–320 for music you care about, 128 for voice or when size matters most.

Is my file uploaded?+

No. The WAV is decoded and the MP3 encoded in your browser with a JavaScript port of the LAME encoder.

How much smaller will it be?+

Usually 8–12× smaller than the WAV, depending on the bitrate you choose.

Is any quality lost?+

MP3 is lossy, so yes — but at 192 kbps and above it's hard to hear on most material.

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.
