MP3 Compressor
What this tool does
Compress browser-supported audio by exporting it as MP3 with a selected bitrate.
When to use it
Use it for voice notes, podcasts, ringtone snippets, lectures, and audio uploads that need a smaller file size.
Privacy and local processing
Audio is decoded and encoded locally in the browser.
Limitations
Audio support depends on browser codecs. Re-encoding can reduce quality, especially at low bitrates.
Tips
Use lower bitrates for speech and higher bitrates for music. Trim silence before compressing for better results.
