How to use Compress audio

Select your files in the private workspace above. Supported inputs: MP3, WAV, M4A, FLAC, OGG, OPUS, AAC.
Review the settings, then start. The workspace uploads and processes your files on the server.
Check the output and download it. Delete files when finished, or let them expire automatically after one hour.

Create an MP3 at 128 kbps by default, with optional mono output. Lower bitrate usually reduces size; output size still depends on duration.

Mono can suit speech recordings. It combines the listening channels and should be avoided when stereo positioning matters.

Up to 100 MB per file. One input per job. Outputs use MP3 format. Busy queues may ask you to try again shortly.

No. Every tool works for guests. Your favorites and saved settings stay on this device and do not include file contents.
