About the WAV to MP3

WAV to MP3 converts WAV audio into MP3, right in your browser. WAV is uncompressed and completely lossless: studio-perfect quality but large files, the standard for editing and mastering. MP3 is the most universal audio format — it plays on virtually every phone, car stereo, browser and app, which is why it is still the safest choice for sharing.

Converting WAV to MP3 makes the file play anywhere — any phone, any car, any old player and any app — with no compatibility worries. You are going from a lossless source to a compressed format, so choose a higher bitrate for the best result — 320 kbps is virtually indistinguishable for most listeners. Everything runs on your device with a WebAssembly build of ffmpeg, so your file is never uploaded — it is private, free and has no watermark. The audio engine is downloaded once (shared with the other audio and video tools) and then cached, so repeat conversions start quickly.

Frequently asked questions

Is my WAV file uploaded?

No. The conversion runs entirely in your browser with ffmpeg (WebAssembly). Your file never leaves your device.

Will I lose quality converting WAV to MP3?

You are going from a lossless source to a compressed format, so choose a higher bitrate for the best result — 320 kbps is virtually indistinguishable for most listeners.

What bitrate should I choose?

For MP3, 192 kbps is a good balance and 320 kbps is near-transparent. Lossless targets (WAV, FLAC, AIFF) ignore bitrate and keep full quality.

Can I convert more than one file?

Convert them one after another — each stays private on your own device, with nothing uploaded.
