About the MP3 to WAV
MP3 to WAV converts MP3 audio into WAV, right in your browser. MP3 is the most universal audio format — it plays on virtually every phone, car stereo, browser and app, which is why it is still the safest choice for sharing. WAV is uncompressed and completely lossless: studio-perfect quality but large files, the standard for editing and mastering.
Converting MP3 to WAV gives you an uncompressed copy that audio editors and DAWs accept without any fuss. Note that converting a compressed file to a lossless one does not restore lost quality — it simply stores the same audio uncompressed, which is what editing software expects. Everything runs on your device with a WebAssembly build of ffmpeg, so your file is never uploaded — it is private, free and has no watermark. The audio engine is downloaded once (shared with the other audio and video tools) and then cached, so repeat conversions start quickly.
Frequently asked questions
Is my MP3 file uploaded?
No. The conversion runs entirely in your browser with ffmpeg (WebAssembly). Your file never leaves your device.
Will I lose quality converting MP3 to WAV?
Note that converting a compressed file to a lossless one does not restore lost quality — it simply stores the same audio uncompressed, which is what editing software expects.
What bitrate should I choose?
For WAV, 192 kbps is a good balance and 320 kbps is near-transparent. Lossless targets (WAV, FLAC, AIFF) ignore bitrate and keep full quality.
Can I convert more than one file?
Convert them one after another — each stays private on your own device, with nothing uploaded.
