Why Video Compressor?
FFmpeg WASM runs the actual ffmpeg binary inside your browser sandbox — the same encoder powering professional video pipelines. Most online compressors upload your file to a server (slow, with size caps and privacy questions); this one processes locally with no file-size ceiling beyond your device's RAM.
Video Compressor keeps the job narrow: shrink large videos for slack, email, and the web — entirely on-device with the real ffmpeg binary. It is built for the small but frequent moments when opening a heavyweight editor, installing a package, or uploading sensitive work to a random service is more friction than the task deserves.
