About Video Compression
Video compression can significantly reduce video file size, making storage and sharing easier
- This tool uses a WebAssembly version of FFmpeg to compress videos in your browser, outputting widely compatible MP4 (H.264 + AAC) files
- Supports common formats such as mp4, mov, avi, mkv, webm, flv, with adjustable compression quality and resolution
- Videos can be previewed and downloaded after compression
- Since processing happens locally in your browser, compression speed depends on your device performance; smaller video files (e.g. under 500MB) are recommended
Video compression is very useful for daily video editing, social media sharing, and saving storage space. Rest assured, all processing is done in your browser and nothing is uploaded to any server.
