A free online MP3 compressor that makes an MP3 smaller in seconds, right in your browser. Drop in a file, drag the slider to pick how much to compress, watch the estimated new size update as you go, and download the smaller MP3.
Useful for emailing a song, uploading to a site, sending a track over WhatsApp or Discord, shrinking a podcast episode, or clearing space.
No upload, no sign up, no watermark, no file size limit. The whole thing runs on your device, so your audio stays private.
