Video Compressor

Video Compressor is a free online tool for reducing video file sizes. It combines HTML5 Canvas API and MediaRecorder API — browser-native technologies — to perform all processing entirely on the client side. Your video files are never uploaded to any server, so you can safely compress even sensitive videos.

Fine-tune compression with adjustable frame rates (15/24/30fps), bitrate (200-8000kbps), and resolution to match your needs and environment. High Quality mode maintains original resolution while adjusting bitrate; Medium mode scales to HD (1280px) for balanced compression; Low mode reduces to 480p for maximum file size reduction.

Real-time estimated file size and processing time help you find optimal settings before compression starts. Supports major video formats including MP4, WebM, MOV, and AVI. Perfect for social media uploads, email attachments, storage savings, and more.
