I need to convert an audio file to MP3
Got a WAV, M4A or OGG that won't play or upload? Convert it to MP3. The format that works everywhere.
To make an audio file play everywhere, convert it to MP3: it's the most universally supported format, accepted by virtually every player, phone and upload form. Our MP3 Converter handles WAV, M4A, OGG and more in your browser, so the file is never uploaded. Choose a higher bitrate for music, or a smaller one for speech.

- 4
Download and use it
Save the MP3, it'll play on any device or upload where the original format was rejected.
- Converting a compressed file (like M4A) to MP3 at a low bitrate, stacking quality loss. Keep a decent bitrate.
- Using MP3 for lossless archiving. If you need perfect quality, keep the WAV/FLAC original too.
- Renaming the extension instead of converting. The file needs re-encoding to actually become MP3.
