About Compress MP3
Re-encode an MP3 at a lower bitrate (typically 128 kbps) to halve the file size while keeping the audio recognisable. Best for podcasts and voice notes.
Frequently asked questions
Will music sound bad?
At 128 kbps a trained ear notices artifacts on cymbals and high-frequency content. Keep music at 192+ kbps.
Can I make it smaller than 128 kbps?
Yes, but voice will start sounding hollow below 96 kbps.
