How to use this tool

To convert WAV to MP3, choose the WAV file, pick 128, 192 or 320 kbps and press Create file. WAV is uncompressed, so a three-minute song takes about 32 MB; as a 192 kbps MP3 it is about 4.3 MB and plays on every phone, car stereo and app. The conversion runs in your browser, the audio stays on your device and the MP3 keeps your file name.

Which bitrate should I choose?

• 128 kbps: speech, podcasts and voice notes; about 1 MB per minute • 192 kbps: music and general use; about 1.4 MB per minute • 320 kbps: the highest MP3 quality, for music you care about; about 2.4 MB per minute For background music in TikTok, Reels or YouTube videos, 192 kbps is plenty; use 320 kbps for tracks you release on SoundCloud or Bandcamp.

WAV vs MP3

WAV stores every sample with no compression, which makes it ideal for recording and editing but bulky to share. MP3 removes sounds people are least likely to hear, cutting the size by 80–90%. Keep the WAV as your master for future edits, and share the MP3.

Output details

The MP3 is stereo at 44.1 kHz with a constant bitrate, which every player supports. Mono WAV files are saved as stereo with the same sound on both sides. 16-, 24- and 32-bit WAV files from studios, DAWs and field recorders all convert.
