Try clearing filters or adjusting your search — most categories have dozens of tools once you widen the net.
Convert between video formats (MP4, WebM, MOV, AVI), compress oversized clips down to a target size, or strip the audio track entirely. All running on your own device via FFmpeg compiled to WebAssembly, so your voice memos, home videos, and work-in-progress clips never leave. Speed depends on your device: a few seconds for a short MP4 on a laptop, several minutes for a long clip on a phone. The only hard limit is your browser's memory, which handles most things under 500MB. Because nothing uploads, there is no waiting in a queue, no rate limit, and no chance your draft lands on someone else's server.
MP4, WebM, MOV, and AVI on input; MP4 and WebM on output. Audio tracks inside videos can be MP3, AAC, Opus, or Vorbis — the tools transcode or strip them as needed.
No server limit — processing happens on your device. Files over 500MB may be slow depending on your device's memory and CPU. FFmpeg-wasm runs single-threaded by default; multithread mode (faster) requires Cross-Origin Isolation, which this site enables on /tools/* routes.
Some — the compressor uses x264 / VP9 with a target bitrate you pick. Default presets aim for visually-similar output at 30-60% of the original size. For larger reductions, lower the target bitrate; you trade file size against quality.
