How to cut an MP3 or other audio file
Updated 21 October 2026
Tool for this guide: Trim audio
Short answer: open trim audio, add the file, type the start and end times, tick Fade in and Fade out for smooth edges, choose a format and download.
Step by step
- Open trim audio and add an MP3, M4A, WAV, FLAC or OGG file, or a video to use its sound.
- Type the start and end times.
- Tick Fade in and Fade out if you want smooth edges.
- Choose MP3, M4A, WAV or iPhone ringtone (M4R).
- Download.
Everything happens in your browser, so the file is never uploaded.
Finding the right times
Play the file in any music or video player first and note where the part you want starts and ends. Leave half a second extra at each end; the fades will smooth it out.
