Drop a WAV
Decoded in the browser, then saved as MP3. You can drop several files.
MP3, WAV, M4A, OGG, OPUS, AAC, FLAC
A higher bitrate keeps more detail and makes a larger file.

What does a WAV to MP3 converter do?
A WAV to MP3 converter compresses an uncompressed WAV recording into a much smaller MP3 file. WAV stores every audio sample, which gives the best quality and a large file. MP3 discards some detail to save space, which makes it easier to email, upload or play on almost any device. This tool opens a WAV from a recorder or a DAW, decodes it in your browser and encodes an MP3 at 128, 192, 256 or 320 kbps. The default is 192 kbps. Higher bitrates keep more detail and make larger files. Everything runs on your own device, so the recording is not uploaded and no copy is kept. The tool does not create M4A, OGG or FLAC files. It is free, with no account and no watermark.
How to use it
- Open the file A .wav file from a recorder or a DAW.
- Pick a bitrate 192 kbps is the default. Higher keeps more detail and makes a larger MP3.
- Download Download the MP3. Nothing is uploaded.
What the converter does
The browser decodes the file to audio samples, then saves an MP3. It does not create M4A, OGG, FLAC or M4R. If a video or unusual file will not open, the browser could not read its audio.
FAQ
Is the file uploaded?
No. Your WAV is decoded and encoded to MP3 in your browser, so it never leaves your device and no copy is kept. That is useful for unreleased music, interviews and other recordings you would not want on someone else's server. Closing or reloading the tab discards the file. You must own the rights to the audio you convert.
Why is MP3 not identical to WAV?
A WAV file stores every sample, while MP3 discards some detail to make a much smaller file, so the two cannot be identical. The MP3 bitrate sets the trade-off, from 128 to 320 kbps, with 192 kbps as the default. Higher values keep more detail and produce a larger file. If you need the original quality, keep your WAV file. This page saves an MP3.
What if decode fails?
Open the page in another browser. A WAV from a recorder or a DAW normally opens, but an unusual encoding may not decode in every browser. If the browser cannot read the audio, the tool cannot convert it, and no upload is involved at any step.
