Why convert to MP3?
MP3 is still the most compatible audio format: it plays in every car stereo, phone, music app and editing tool. This MP3 converter accepts both audio and video files, so you can turn a WAV recording, an M4A voice memo or the soundtrack of a video into a small, high-quality MP3 in one step.
- You want the audio from a video in MOV, WEBM, MKV or AVI format.
- A voice memo (M4A) or a recording (WAV, FLAC) needs to be smaller or more compatible.
- Your car stereo, speaker or app only plays MP3 files.
Tips for the best result
- We use high-quality variable bitrate (around 190 kbps), which sounds great while keeping files small.
- From a video, only the soundtrack is kept.
- Converting from one compressed format to another (like OGG to MP3) always loses a little quality. Start from the best original you have.
