How to trim MP3 audio
- Drop an MP3, WAV, OGG or M4A file into the upload area, or click to select it from your device.
- Wait for the file to decode so its full duration appears.
- Enter the start and end time, in seconds, for the section you want to keep.
- Click Trim Audio and download the resulting trimmed.wav file.
FAQs
Does the trimmer upload my audio anywhere?
No. The audio is decoded and cut entirely in your browser, so your file never leaves your device.
Can I cut a clip from the middle of the file?
Yes. Set any start and end time inside the track and only that exact section will be exported.
What format is the trimmed file saved as?
You can save the trimmed section as WAV (lossless, built into every browser) or MP3 (smaller, encoded in your browser).
Can I trim audio that is not an MP3?
Yes. WAV, OGG, M4A, AAC and FLAC files are supported as long as your browser can decode them.

Tips and Limits
Choose MP3 for a smaller download or WAV for lossless quality. One file is processed at a time; MP3 encoding can take a few seconds.
