About Video Compressor

This tool compresses video files entirely in your browser. No upload, no server, no tracking. Your original video never leaves your device.

Smart Compression

Choose from three compression levels. Maximum saves the most space, Balanced is recommended for everyday use, and Best Quality preserves near-original fidelity.

Resolution Control

Downscale to 1080p, 720p, or lower to dramatically reduce file size. Halving resolution can quarter the file size for massive savings.

100% Private

All processing uses the browser's built-in video encoder via canvas capture and MediaRecorder API. Zero bytes are sent to any server. Your video stays on your machine.

Before and After Stats

Compare original and compressed videos with side-by-side statistics. See exact savings in percentage and file size before downloading.

Supported input formats: MP4, WebM, MOV, AVI, MKV, and most browser-playable video formats. Output is WebM (broadest support) or MP4.
