Video Compressor
Compress compatible MP4, MOV and WebM files locally with adjustable quality and resolution.
Files stay on your device. No uploads.Local processing. Maximum 80 MB, 180 seconds and 1920×1080 pixels (or equivalent portrait dimensions). Native export depends on browser codec support. Video export runs in real time: keep this tab visible. MP4, MOV and WebM containers are accepted only when this browser can decode their contents.
How to use Video Compressor
- Choose a compatible MP4, MOV or WebM.
- Set output quality and maximum side length. Lower settings generally reduce size.
- Export while keeping this tab visible, then compare original/result size before downloading.
Formats and limitations
Native browser export, up to 80 MB, 180 seconds and 1080p-equivalent input. WebM/MP4 support and timing vary. FFmpeg.wasm could not be installed in this environment; there is no server fallback. An optimized original may already be smaller.
Privacy and temporary data
Video remains in this tab. Export uses local canvas, audio and recording APIs and temporarily holds the output in memory.
