Convert MP3 audio to uncompressed WAV in your browser. WAV is ideal for editing and mastering because it stores audio without lossy compression — though it won’t restore detail already lost by the MP3.
Frequently asked questions
Why convert MP3 to WAV?
WAV is uncompressed, so it’s the preferred format for audio editing, mastering, and software that needs raw PCM input.
Will the WAV sound better than the MP3?
No — converting can’t recover detail the MP3 already discarded. It simply stores the audio without further lossy compression.
Why is the WAV file so much larger?
WAV stores uncompressed audio, so files are roughly ten times the size of the equivalent MP3.
Is it private?
Yes — conversion runs in your browser via WebAssembly with no uploads.
