How to compress an audio file
Drop your audio files above.
Pick the level (160, 128 or 96 kbps) or a maximum size.
Click Compress and download the MP3s.
How it works
- Audio (MP3, WAV, M4A, FLAC, OGG)
- Audio is re-encoded to MP3 at the chosen bitrate. A WAV or FLAC file becomes 5–10 times smaller.
Everything happens in your browser: your files are never uploaded to a server.
