Audio to WAV
Convert MP3, M4A, OGG or FLAC to universal WAV — decoded on your device.
About this converter
Whatever audio your browser can play, this converts to WAV: MP3, M4A/AAC, OGG, FLAC, Opus. Decode happens on your device, a waveform preview and player confirm the result, and the download is a standard 16-bit WAV that opens absolutely anywhere. Free forever, no account.
Why WAV, and what conversion honestly does
WAV is audio's lowest common denominator — uncompressed PCM samples in a container from 1991 that samplers, courtroom evidence systems, old editing suites, embedded devices and picky upload forms all accept without argument. Two honest physics notes. First, size: WAV trades compression for universality at roughly 10 MB per stereo minute — the size calculator does the arithmetic for your duration. Second, quality: converting an MP3 to WAV cannot restore what MP3 encoding discarded — the decoded audio is repackaged losslessly from here on, no better and no worse than what you heard. That's exactly what "convert to WAV" should mean, and exactly what tools that promise "quality enhancement" are fibbing about. The reverse direction (WAV to MP3) needs an encoder browsers don't ship, so this site honestly doesn't offer it. Trim or resample the result next door.
Frequently asked questions
Which formats can it convert?
Anything your browser decodes: MP3, M4A/AAC, OGG Vorbis, FLAC, Opus and WebM audio. If the file plays in a browser tab, it converts here — same decoder.
Does converting to WAV improve quality?
No, and nothing can — compression losses are permanent. WAV conversion repackages the decoded audio losslessly, which is what compatibility needs and all it needs.
Why is the WAV so much bigger than my MP3?
WAV is uncompressed: ~10 MB per stereo minute at CD quality, versus ~1 MB for 128 kbps MP3. The size IS the universality.
Can I convert WAV to MP3 here?
Honestly, no — browsers ship MP3 decoders but not encoders, and this site doesn't pretend otherwise. Desktop tools like Audacity do that job well.
