Video Compressor

Video compression re-encodes the video at a lower bitrate, reducing file size. The quality slider controls the trade-off - lower quality = smaller file. At medium quality, most compression is imperceptible.

Input: MP4, WebM, MOV, AVI, and other formats your browser supports. Output: WebM (for browser compatibility). The Pro version supports MP4 output via ffmpeg.

No - compression uses the MediaRecorder API in your browser. Your video never leaves your device. Large videos may take longer to process on older devices.

Typically 40-80% reduction depending on the original quality and your chosen settings. A 100MB video can often be compressed to 20-40MB with minimal visible quality loss.
