MeloCutCompress MP3 and audio files
Make an MP3, voice note or recording much smaller so it fits email, chat or upload limits. Pick a lower quality and see the new size.
How it works
Any MP3, WAV, M4A or other audio file, or a video.
64 kbps is selected. Use 96 or 128 kbps for music.
Press Convert. The new size is shown before you download.
How much smaller?
An MP3's size depends almost only on its bitrate and length:
- 320 kbps: about 2.4 MB per minute.
- 128 kbps: about 1 MB per minute.
- 96 kbps: about 0.7 MB per minute.
- 64 kbps: about 0.5 MB per minute. Fine for speech, podcasts and voice notes.
So a 320 kbps song gets about five times smaller at 64 kbps.
Even smaller
- Turn on Mono in Effects. For speech you won't hear a difference.
- Drag on the waveform to keep only the part you need.
- Turn on Remove silences to cut long pauses out of recordings.
What about quality?
Lower bitrates remove detail you mostly hear in music: 64 kbps sounds fine for voices, use 96 to 128 kbps for songs. Compressing can't make a file sound better, so keep your original if you might need it later.
