Compress Video
Shrink MP4, MOV and WebM files to a target size in your browser — nothing is uploaded.
Common questions
How does Compress Video work?
Choose a target size (like under 25 MB for Zalo or email) or a quality level, optionally cap the resolution, then press Compress. Your browser decodes and re-encodes the video with WebCodecs and hands you a smaller file to download.
Can I trust the output for production?
The video is never uploaded anywhere. Everything — decoding, encoding and the download — happens on your device using your browser's built-in WebCodecs API.
Will this tool stay free?
Compress Video is free, with no sign-up and no watermark.
