Yes. After the initial page load, Video Compressor runs entirely on your device with no internet connection needed. All processing is done locally.
Typical compression reduces video file sizes by 50-80% depending on the CRF setting and source quality. A 100MB video can often be reduced to 20-30MB with minimal visible quality loss at CRF 23.
Video Compressor uses H.264/AV1 encoding via FFmpeg to reduce MP4/MOV/WebM files — the most compute-intensive compression. Image Compressor uses Canvas API for JPG/PNG/WebP. PDF Compressor optimizes document internals. Each uses format-appropriate compression algorithms.
CRF (Constant Rate Factor) controls quality: 0 is lossless, 51 is worst. For web uploads, CRF 23-28 is typical (good quality, small file). For archival, use CRF 18-22. For maximum compression (social media), CRF 28-32 works well.
Yes. All video compression runs locally using FFmpeg WASM compiled to WebAssembly. Your video never leaves your browser — no uploads, no server processing, complete privacy for your content.
