Explore channelsAn MP3 to WAV converter takes your MP3 file and repackages it as uncompressed 16-bit PCM WAV, the format most DAWs, samplers and older hardware expect. This tool runs entirely in your browser using the Web Audio API - your files never touch a server, and there is no bitrate to choose, since WAV output is always uncompressed.
Converting is two steps, no settings to hunt for:
No. MP3 is a lossy format - once audio data is removed during MP3 encoding, it is gone permanently. Converting to WAV does not bring it back. What it does is stop any further quality loss: the WAV file holds the same audio as the MP3, uncompressed and unchanged, so nothing more gets thrown away in editing or playback chains that re-encode compressed input.
Compatibility. Plenty of DAWs, hardware samplers, and CDJs either require WAV or work noticeably better with it than with compressed formats. If a tool in your workflow rejects MP3 or handles it unreliably, converting to WAV solves the problem even though the underlying audio quality is unchanged.
| MP3 (source) | WAV (converted) | |
|---|---|---|
| Type | Lossy | Lossless (PCM) |
| Quality | Whatever the MP3 already had | Identical to the MP3 - not restored |
| 5 min song | ~12 MB at 320 kbps | ~50 MB |
| Compatibility | Universal | Universal, required by some DAWs/hardware |
The file gets bigger and the format changes, but the actual sound does not improve - the ceiling was set the moment the MP3 was encoded.
Drop in a whole folder of MP3s and convert them all in one pass. When they finish, download the entire batch as a single ZIP instead of saving each file by hand.
If MP3 is your only copy of a track, upload it to SoundCloud as-is - converting to WAV first will not improve what SoundCloud receives, since you cannot recover quality that is already gone. Always upload your best available source, whether that is WAV, FLAC, or MP3, rather than converting up from a lossy file.

No. MP3 is lossy, so the audio data removed during MP3 encoding is gone for good. Converting to WAV repackages what remains losslessly - it stops further quality loss, but it does not restore what the MP3 already threw away.
Because some DAWs, samplers, hardware players, and CDJs need WAV or do not support MP3 at all. Converting gives you a compatible, uncompressed file to drop into that workflow.
No. Conversion happens entirely in your browser using the Web Audio API. Your audio never leaves your device.
Much bigger than the MP3. A typical 5-minute MP3 at 320 kbps (about 12 MB) becomes roughly 50 MB as uncompressed 16-bit PCM WAV.
Yes. Add as many files as you want, convert them all, and download everything as one ZIP.
Upload lossless whenever you have it - WAV or FLAC. If you only have an MP3, upload that as-is rather than converting to WAV first, since you cannot recover quality that is already gone.
100 MB per MP3 file. There is no limit on the number of files.
Need the reverse direction? The full audio converter handles MP3, M4A, FLAC, OGG, AAC and Opus to MP3 or WAV. Converting M4A to WAV instead? Use the M4A to WAV converter. Need to shrink an MP3 instead? Try the MP3 compressor. Cut and trim with the MP3 cutter, or add smooth fades with the audio fade tool. Working from WAV? Use the WAV to MP3 converter.
