Frequently Asked Questions
How do I cut an MP3 online?
Upload an MP3, enter the start and end time, click Cut MP3, and download the trimmed audio file.
What time format can I use?
Use plain seconds, MM:SS, or HH:MM:SS for the start and end times — for example 90, 01:30, or 00:01:30.
Will cutting reduce the audio quality?
No. The selected section is re-encoded to a standard 192 kbps MP3, which keeps quality close to the original.
Are MP3 files uploaded?
No. Cutting runs in your browser with FFmpeg WASM, so your audio never leaves your device.
