Upload a file from your device. Drag and drop or use the file picker to select your document.
Yes. After the initial page load, Video Compressor runs entirely on your device with no internet connection needed. All processing is done locally.
Three methods: CRF (Constant Rate Factor) for quality-based compression, resolution scaling to reduce dimensions, and bitrate control for predictable file sizes. Combine methods for maximum reduction.
CRF (Constant Rate Factor) controls quality. Lower CRF = higher quality/larger file. Typical values: 18 (high quality), 23 (default/good balance), 28 (smaller file). 18-23 is recommended for most use cases.
MP4, MOV, WebM, MKV, and AVI inputs are supported. Output is typically MP4 or WebM. The tool uses FFmpeg for encoding.
Yes. The tool includes a quality preview feature so you can check the visual result at your chosen CRF/bitrate settings before committing to the full compression.
No. All compression runs locally in your browser using FFmpeg WASM. Your video never leaves your device.
