About MP3 Compressor
Make MP3 and other audio files smaller by lowering the bitrate. Choose 96 kbps for music that still sounds good, or 64 kbps and below for speech like podcasts, audiobooks and voice notes. Convert to mono for even smaller files. The result is always an MP3 that plays everywhere.
Frequently asked questions
Which bitrate should I pick?
96–128 kbps works well for music. 48–64 kbps is enough for speech and voice recordings.
What does mono do?
Mono mixes both channels into one, which nearly halves the size. It's ideal for voice, but music loses its stereo effect.
Can I compress other audio formats?
Yes. WAV, M4A, OGG, FLAC and more can be uploaded and are saved as smaller MP3 files.
