Keep or remove — your choice
Keep selection
Exports only the highlighted part. This is the usual way to cut a chorus or a single sentence out of a longer recording.
Remove selection
Exports everything except the highlighted part, joining the audio before and after it. Useful for cutting a mistake or a long pause out of the middle of a file.
Fade in and fade out apply a short ramp at the start and end of the exported file so a cut does not click. Play selection always plays the result you are about to download.
MP3 Cutter FAQ
Does trimming an MP3 reduce quality?
Re-encoding to MP3 loses a little quality. Choose WAV export if you need the original audio untouched.
Can I cut a song's chorus for a ringtone?
Yes. Drag the handles around the chorus, preview it, then export.
Does the file get uploaded to a server?
No. The MP3 is read locally and decoded with the Web Audio API, and every step after that runs in the tab. You can check the Network panel in your browser: trimming makes no requests at all.
Should I download WAV or MP3?
WAV is uncompressed 16-bit PCM and keeps the decoded audio exactly, which is what you want if the clip goes back into editing. MP3 is far smaller (about 1 MB per minute at 192 kbps) but re-encodes, adding a second generation of lossy compression. For a ringtone or a quick share, MP3 is fine.
How long a file can it handle?
The whole file is decoded into memory, so the practical ceiling is around 100 MB. A one-hour 128 kbps podcast is about 56 MB and works; very long 48 kHz stereo WAV files can get slow on a phone.
