How to convert audio
- Drop an audio file in: MP3, M4A, WAV, OGG, Opus, FLAC, or even a video.
- Choose MP3, M4A or WAV, and for MP3 the quality.
- Press Convert, listen to the result, and save.
Which format should I choose?
| Format | Best for | Size per minute |
|---|---|---|
| MP3 | Playing anywhere: phones, cars, speakers, old players | about 1–2.4 MB |
| M4A (AAC) | Apple devices, podcasts; smaller than MP3 at the same quality | about 1.2 MB |
| WAV | Editing in audio software; uncompressed | about 11 MB |
Common conversions
- WAV to MP3: shrink big recordings by about 90% for sharing.
- FLAC to MP3: play lossless music on devices that don’t support FLAC.
- OGG or Opus to MP3: make voice notes and game audio play everywhere.
- M4A to MP3: for older players and some car stereos.
- MP3 to WAV: for editing software that prefers WAV.
Converting to a compressed format can’t add quality: an MP3 made from a 128 kbps file won’t sound better at 320 kbps.
Lossy and lossless formats
WAV and FLAC are lossless: they keep every detail of the recording, so they’re large. MP3 and M4A (AAC) are lossy: they remove sounds people can’t easily hear, making files around ten times smaller. Converting lossless to lossy is fine for listening and sharing. Converting one lossy format to another (for example MP3 to M4A) loses a little more detail each time, so keep the original if you can.
Private recordings stay private
Voice memos, interviews and unreleased music are converted on your own device. Nothing is uploaded or stored, so you don’t need to read anyone’s privacy policy before converting.
