How to convert WAV to MP3
WAV recordings are about ten times bigger than MP3. Converting makes them easy to email, upload and play on any device.
- Drop your WAV file into the box above, or add it from a link.
- MP3 is already selected. Use the settings button next to it to change size, quality or other options.
- Select Convert, then download your MP3 file.
To do this from your own code, call the FileForge API with "output_format": "mp3".
Good to know
- 192 kbps is near-transparent for most listeners; use 320 kbps for music you care about.
- 128 kbps is plenty for voice recordings and podcasts.
- Keep the WAV if you'll edit the audio again: MP3 is lossy.
About the formats
.wav
WAV is uncompressed audio, as recorded. It's the standard for editing and for software that needs raw sound, but files are about ten times bigger than MP3.
.mp3
MP3 is the universal audio format: every phone, car stereo, speaker and app plays it. It uses lossy compression, so a 3-minute song is a few megabytes.
