Frequently asked questions
Does the cut land on the exact second I marked?
Almost. The tool copies the section without re-encoding — that's why it's instant and lossless — and warns on screen that the cut can start up to ~2 seconds before the point you mark. In practice, for audio that slack is usually much smaller than for video, but the honest promise is this: close to the point, not down to the millisecond.
Does the song lose quality when cut?
No. Nothing is re-encoded: the section comes out exactly as it is in the original file. An .mp3 stays an .mp3, a .wav stays a .wav — same sound, just shorter.
Can I use the cut as a ringtone?
You can. Trim the chorus or the part you want and download it — the file comes out in the same format it went in, which is what most phones accept as a ringtone. Then just point the ringtone to the file in your device settings.
Which formats are accepted?
.mp3, .wav and .m4a — which covers downloaded music, voice recordings and iPhone audio. The section comes out in the same format it went in.
What is the maximum file size?
300 MB on a computer and 80 MB on a phone — to keep the browser from freezing, and the tool warns you before downloading anything. Audio rarely goes past that; if yours does, an installed app handles it better.
Is my audio uploaded to a server?
No. The cut happens inside your browser, on your device. The first time, the page downloads the conversion engine (~31 MB) — the engine comes to you, your audio never goes to it. After that it stays in your browser cache.
