MP3 to WAV
Convert MP3 to uncompressed 16- or 24-bit WAV for editors, DJ software and CD burning.
MP3
MP3 is the most widely supported audio format: every phone, car, speaker and website plays it.
MP3 is lossy. Converting it to a lossless format doesn’t restore detail, but gives editors the WAV they expect.
WAV
WAV is uncompressed audio from recorders, DAWs and CD rips. A minute of CD-quality stereo takes about 10 MB.
Every audio editor, DJ program and burning tool reads WAV, which makes it the safe format for further work.
How it works
- Your browser decodes the MP3 file at its own sample rate, so a 44.1 kHz song stays 44.1 kHz. Rare formats such as WMA or AMR go through FFmpeg compiled to WebAssembly.
- WAV is written by our own code, sample for sample, in 16- or 24-bit.
- Several files are converted one after another and can be downloaded together as a ZIP.
Questions
Are my files uploaded?
No. Decoding and encoding run on this device. Only the encoder code (130 KB for MP3) is downloaded once.
Which MP3 quality should I pick?
192 kbps or VBR V2 sounds the same as the original to almost everyone. Use 320 kbps if a site asks for it, 64 kbps for speech only.
Does converting MP3 to FLAC or WAV improve quality?
No. A lossless file keeps exactly what the MP3 had, it can’t bring back what MP3 removed. It’s useful when an editor or a DJ program needs WAV.
