Convert, trim, and bleep-censor videos right in your browser — MP4, MOV, MKV, WebM to MP3, WAV and more, plus rotate, flip, compress and mute. Nothing is uploaded, ever: FFmpeg runs locally on your device via WebAssembly. Also includes an instant fast-cut / frame-exact trimmer, a bleep censor for swears and private parts, and a subtitle toolkit (SRT→VTT, shift delay, merge). No accounts, no watermarks, free.
