Audio Trimmer
Trims an audio file to a selected time range, with optional fade-in and fade-out, a waveform display to find the cut points, and WAV or MP3 export. Decoding and cutting happen in your browser via the Web Audio API.
Runs 100% in your browser — your files never leave your device.

Notes
- WAV export is instant and lossless. MP3 export downloads the ffmpeg engine on first use.
