About trimming MP3
Add an MP3, mark the start and end of the part you want on the waveform and download the result. Everything happens in your browser on your own device: the file is never uploaded, so there is no queue to wait for — processing starts immediately.
One thing worth knowing about MP3: it is a lossy format, and saving a fragment re-encodes the audio. The difference is normally inaudible, but if you plan to cut the same file repeatedly, keep the original at hand and go back to it each time rather than to your previous result.
Fade in and fade out are set separately: they remove the click at the cut boundary, which is especially noticeable when the cut lands in the middle of a note or a word. Half a second of fade is usually enough for a ringtone, a full second for video work.
Frequently asked questions
How do I cut an MP3 without losing quality?
Completely lossless is not possible: MP3 compresses with loss and a saved fragment is re-encoded. To keep the loss minimal, cut from the original file rather than from something you trimmed earlier — that way the audio is re-compressed only once.
Can I trim other formats?
Yes. The tool accepts WAV, M4A, OGG, FLAC and anything else your browser can decode, not just MP3. The output can be MP3 or WAV.
What are fade in and fade out for?
They remove the click at the cut. If the fragment starts or ends mid-sound, the abrupt edge is heard as a pop; half a second of fade hides it.
Is my file uploaded to a server?
No. Trimming runs in your browser on your own device, so personal recordings and voice messages are safe to cut here.
How do I turn a fragment into a ringtone?
There is a dedicated tool for that — it already accounts for the length limit and the format phones accept.
