MP3 Cutter and Audio Cutter
Cut a recording down to the part you actually want.
Free audio cutter: cut an MP3, WAV or M4A down to the part you want, for a ringtone, a clip or a sample. Often without re-encoding, and never uploaded.
What this tool is for
Cutting a recording down is the most ordinary thing anyone does to audio, and until recently this site could not do it at all — the video trimmer refused audio files. It cuts by copying rather than re-encoding, so the part you keep is bit-for-bit what it was, and the whole thing finishes in about the time it takes to read the file.
Cutting without re-encoding
Left on its default, the cut copies the original audio exactly, so an MP3 trimmed here sounds identical to the source and the job is almost instant. The trade-off is that a lossless cut can only land on the boundaries of the audio's own frames, a few hundredths of a second apart. Turn re-encoding on if you need the cut exact to the millisecond.
Making a ringtone
Trim the part you want to about 30 seconds, then add a short fade in and out with Fade Audio so it does not start or stop abruptly. iPhones need the ringtone as M4A; Android accepts MP3.
Setting the start and end
Type the times as seconds or minutes and seconds, such as 1:05. Listen back to the result and adjust: it is quicker to run the cut twice than to hunt for the exact frame the first time.
How to use it
- Add your files. Drop them on the page or choose them. They stay on your device.
- Set the output format and quality. The defaults suit most files.
- Press convert and save the results, individually or as one ZIP.
Questions
Does trimming lose quality?
Not by default. The section you keep is copied out of the original untouched, so an MP3 stays exactly the MP3 it was. Re-encoding is offered as a separate option for when you want to drop the bitrate at the same time, and only then is anything discarded.
How exact is the cut?
Within a few milliseconds. Audio frames are small and independent, so a copy cut lands almost exactly where you asked — unlike video, where copying forces the cut to the nearest keyframe and can be a second out.
Can I cut out the middle instead of the ends?
Not in one pass. Trim the part before it and the part after it as two separate jobs, then put the two pieces together with Join Audio.
What formats can it trim?
MP3, WAV, FLAC, M4A, AAC, OGG, OPUS, AIFF, WMA and the rest. The output keeps whatever format went in.
