Video files are among the largest files on most devices. A single minute of 1080p video can exceed 100 MB. Compression reduces file size while preserving visual quality, making videos easier to share, upload, and store.
Unlike cloud-based video compressors that upload your files to remote servers, our tool processes everything locally in your browser using FFmpeg compiled to WebAssembly. Your video files never leave your device.
CRF (Constant Rate Factor) controls the quality-to-size tradeoff. Lower CRF values mean higher quality and larger files. Our presets use CRF 23 (High), CRF 28 (Medium), and CRF 35 (Low) to cover common use cases.
MP4 (H.264) is the most widely supported format, compatible with virtually all devices and platforms. WebM (VP8) is an open format preferred for web use. Choose MP4 for maximum compatibility or WebM for open-source workflows.
