Why convert MP3 to WAV?
Convert compressed MP3 audio to lossless 16-bit PCM WAV in your browser. Decoding stays on your device — no server upload.
How this converter works
Drop a MP3 file and the tool decodes it using the Web Audio API, then re-encodes it as WAV. The entire process runs in your browser — your file never uploads to a server, never gets stored, and conversion is typically faster than upload-based tools because there's no network round trip.
The WAV output is uncompressed 16-bit PCM — the standard format for editing in DAWs (Logic Pro, Ableton, Pro Tools, Reaper) and the lossless reference format for audio archives.
FAQ
Is the conversion lossless?
Output is uncompressed 16-bit PCM WAV, which is lossless from the decoded source. If your MP3 was already compressed, that information can't be recovered — but no further loss is introduced.
Will my file be uploaded?
No. The conversion is browser-based using the Web Audio API. Your file stays on your device the entire time.
Maximum file size?
~200 MB is the sweet spot for in-browser processing. Larger files may hit memory limits on phones and older laptops. For batch conversion, use the Loudify app.
