How to trim audio
- Click Choose a file, or drop a file on the box.
- Drag across the waveform to select the part you want to keep. Fine-tune it with Start and End.
- Press Play to listen to the selection.
- Choose MP3 or WAV, turn on Fade in or Fade out if you like, and click Trim and download.
What you can do with it
- Cut a song for a ringtone, an alarm or a video intro, with a one-second fade at each end.
- Shorten a recording: drop the silence at the start, or keep one answer from an interview.
- Pull a clip out of a video: open an MP4 or MOV and keep just the part of the sound you need.
- Split a long lecture: save one part, then select the next and save it again.
Trim as you record
The online voice recorder has the same crop after every recording: stop, drag across the waveform, and crop. The Voice Recorder extension does it too, with Undo, for everything in its library.
Convert without cutting
To change a whole file’s format, use the audio converter.
