MP3 to WAV — vanliga frågor

Why is the WAV so much bigger?+

WAV is uncompressed PCM — roughly 10× an MP3. That's expected: it's the trade-off for a lossless, editing-friendly file.

Does converting to WAV improve quality?+

No. It can't restore detail the MP3 already discarded — but it won't lose any more, which is useful before further editing.

Is it uploaded?+

No — the MP3 is decoded and the WAV is written entirely in your browser.

What sample rate is the WAV?+

The same sample rate as the source MP3, as 16-bit PCM.

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.
