Audio Trimmer (Cut Audio Clips)
Trim an audio file down to exactly the part you want, right here in your browser. Drop in an MP3, WAV, M4A, or OGG, then drag the start and end handles to keep just the section you need. The cut happens entirely on your device, so nothing is uploaded, and the result downloads as a clean WAV file. It is the fast way to grab a clip, drop dead air off the front, or top and tail a recording without installing anything.
How to trim an audio file
- Drop in an audio file, or click to browse for one.
- Set the start and end time to mark the section you want to keep.
- Preview the trimmed clip, then download it as a WAV file.
Examples
Grab a 15 second clip
song.mp3 (a three minute track)
A 15 second WAV containing only the chorus you selected, cut on your device.
Frequently asked questions
Is my audio uploaded anywhere?
No. Nothing is uploaded. The file is decoded and trimmed entirely in your browser using the Web Audio API, so it never leaves your device. The trimmed clip is then encoded and downloaded locally.
What audio formats can I trim?
MP3, WAV, M4A, FLAC, OGG, and other common audio files all work, because the browser decodes them before trimming. You can even drop in the audio track of an MP4 or WebM video. Whatever your browser can play, you can trim.
What format is the trimmed file?
The output is a WAV file. WAV is uncompressed, so the trimmed clip keeps full quality with no extra encoding loss, and it opens in every editor and player. You can convert it to MP3 afterward if you need a smaller file.
Is there a length or file size limit?
There is no fixed length limit, but very large files use more memory because the whole clip is decoded in your browser. Files up to a few hundred megabytes are comfortable on a typical machine. Trimming is instant once the file is decoded.
Does trimming reduce the audio quality?
Trimming itself is lossless: it just keeps a range of the original samples untouched. The only change is that the download is a WAV, which is uncompressed, so the kept section sounds exactly like the source.
