Reduce audio file size, free.

Large audio files can be slow to upload, exceed email attachment limits, or eat into storage on a phone or podcast host. Our free audio compressor re-encodes your file at a lower bitrate to shrink its size while keeping it clearly listenable — ideal for voice recordings, podcasts, and anything where perfect fidelity matters less than a manageable file size.
Upload your file, pick a target bitrate, and download the smaller result. Lower bitrates give the biggest size reduction but will noticeably soften audio quality, especially on music with a lot of detail.
