Audio Trimmer

Cut a clip from an audio file by start and end time and download it as WAV. Runs in your browser.

Frequently asked questions

What formats can I load?

Any audio your browser can decode — typically MP3, WAV, OGG, M4A and FLAC. The trimmed clip is exported as WAV (uncompressed, lossless).

Is my audio uploaded?

No. The file is decoded and trimmed entirely in your browser using the Web Audio API; nothing is sent to a server.

Why WAV and not MP3?

WAV needs no extra encoder and is lossless. If you need MP3, convert the downloaded WAV with an audio converter afterwards.
