Frequently asked questions

Does cutting an MP3 lower its quality?

The selection is re-encoded at a high bitrate so fades can be applied cleanly. The difference from the original is inaudible at the default settings.

Can I cut out a section in the middle?

This tool keeps one continuous part. To remove a middle section from a video, use Remove a Section.

How do I set an M4R as my iPhone ringtone?

Download the M4R, connect your iPhone to a computer and drag the file onto the device in Finder (Mac) or iTunes (Windows). On the phone, choose it in Settings, Sounds and Haptics, Ringtone. Keep it to 40 seconds or less.

How long can an Android ringtone be?

Android accepts MP3 of any length, but 20 to 30 seconds is usual. Save the MP3 in your phone's Ringtones folder or pick it in the sound settings.

Does cutting lower the quality?

The cut part is re-encoded so the fades can be applied. At the default bitrates the difference is not audible.

Is my audio uploaded?

No. Cutting happens in your browser with FFmpeg in WebAssembly.

Can I cut several parts at once?

One part per run. Run the tool again for each section you need.

Does it work on my phone?

Yes, in Safari and Chrome. The handles are sized for touch.
