How to compress an MP3

  1. Drop your MP3 files above.

  2. Pick the level or a maximum size.

  3. Click Compress and download the smaller 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.
