Compress Audio Online

Reduce audio file size by choosing the quality you need.

How to use

  1. Choose an audio file.
  2. Select 64, 96, 128 or 192 kbps.
  3. Compress and download MP3.

What this tool does

Make voice notes, music and recordings lighter for sharing and storage.

Worked example

Twenty minutes at 192 kbit/s takes roughly 28.8 decimal MB; at 96 kbit/s, about 14.4 MB before small overhead differences. Trimming silence reduces duration; lowering bitrate reduces data per second.

Limits that affect the result

WAV is not necessarily smaller. MP3 reduces data lossily and may offer little benefit when the source is already heavily compressed.

Does a smaller file reduce quality?

Yes. Stronger compression creates smaller files but can reduce audio detail.
