Free WAV to MP3 converter

Why convert WAV to MP3?

WAV files are enormous. MP3 makes them small enough to send and store while staying indistinguishable to most ears.

How to convert WAV to MP3

1. Choose your WAV file. Drop it on the box above, or tap to browse. You can pick several files at once.
2. Confirm the target is .mp3. It is preselected when your browser can encode it; otherwise the closest available target is chosen. Adjust quality, size or the other options if you want to.
3. Convert and download. Press Convert, then Download. Your file stays on your device the whole time.

What is a .wav file?

WAV is uncompressed audio: the raw samples, exactly as recorded, with no quality lost and no processing applied. That makes it the format for recording, editing and archiving — and a poor one for sharing, since a few minutes runs to tens of megabytes.

What is a .mp3 file?

MP3 is the audio format everything understands — every phone, car stereo, browser and media player made this century. It is lossy, but at 192 kbps or above most listeners cannot tell it from the original, and its universality outweighs the newer formats' efficiency.

What to expect from this conversion

The audio is decoded and re-encoded with the target codec. Choose 192 kbps or higher for music; speech is perfectly clear at less. Converting between two lossy formats always loses a little, so work from the original where you can. WAV is uncompressed, so the source is pristine and only the target format decides the quality.

Is it private?

Yes, by design. Every conversion happens inside your own browser using your device’s processor — there is no server that receives your WAV file, so there is nothing for anyone to store, scan or leak. You can confirm it yourself: open your browser’s developer tools, watch the Network tab while you convert, and you will see no upload.
