Audio to MP3 Converter

One audio to MP3 converter for every format

MP3 is still the format that plays everywhere: on phones, in cars, on smart speakers and in every music app. Many recordings, however, arrive as WAV, M4A, FLAC or another format that a device or website will not accept. An audio to MP3 converter solves that in one step and usually makes the file much smaller too.

This page reads all common audio formats, plus rarer ones such as AMR, AC3 and CAF. You can add several files at once, choose the bitrate and save each one as a standard MP3. The conversion runs inside your browser, so even private recordings never leave your device. If your sound is inside a video, use our Video to MP3 converter instead.

Which MP3 bitrate should you choose?

The bitrate decides both quality and size. As a rule, 128 kbps is fine for podcasts and voice, 192 kbps is a safe choice for most music, and 320 kbps keeps the most detail from lossless files such as WAV, FLAC and ALAC. Converting to a higher bitrate than the original never adds quality, so there is no need to go above it. Need an even smaller file? Run the result through our MP3 Compressor.
