Audio & video trimmer + mute

Cut a clip's start and end from any MP3, WAV, MP4 or MOV, or strip the audio track from a video entirely — right here in your browser.

Every feature. No limits. No sign-up. No watermark. Nothing uploaded. Free forever. It runs 100% in your browser — your media is processed on your own device via ffmpeg.wasm and never touches a server, so there is nothing to upload, nothing to unlock, and nothing to pay for.
Nothing uploaded, ever. The whole engine (ffmpeg) runs inside your tab. Files never leave your device.
Drop an audio or video file here, or click to choose MP3 · WAV · M4A · MP4 · MOV · WebM · any size
