How to trim an audio file
Open a song, voice memo, podcast, or any MP3, WAV, or M4A file. Drag the ends of the waveform in, or play to a spot and press I or O, to set where it starts and stops, then play it to check. The trimmed audio is saved in its own format. The audio trimmer runs in your browser, so the file stays on your device.

What to expect
- Supported inputs
- MP3, WAV, M4A, FLAC, Ogg, Opus, AAC, AIFF, and other audio this browser’s engine can read, and videos with sound.
- What happens
- The trimmed audio keeps its format and is copied without re-encoding. A fade re-encodes it in the same format. A video’s sound is saved as an MP3, and an AIFF as a WAV.
- Limits
- Without a fade, the start and end land on the nearest packet of sound, a few hundredths of a second at most from your mark.
