Compress video without uploading
The Video Compressor works entirely in your browser. Upload a compatible video file, choose a compression preset or target size, and download the result as a smaller WebM file. Your original video never leaves your device.
Browser-based compression is ideal for private footage, quick sharing, and saving bandwidth on slower connections. The tool uses native MediaRecorder and canvas APIs to re-encode video locally.
Choose the right balance
- High: best visual fidelity with a moderate file size reduction.
- Basic: good quality and smaller output for most sharing needs.
- Low: smallest files for email, chat, or mobile transfer.
- Manual target: set a desired final size in KB when you need tighter control.
Privacy-first compression
Because the compression runs locally, the original file is never uploaded or stored on a remote server. This keeps sensitive recordings, screen captures, and private clips on your own machine while still giving you a smaller shareable output.
