Converting and compressing videos requires users to upload personal content to servers, an inherent privacy risk which is tacitly ignored. Modfy solves this issue by operating entirely in the browser on your local machine. No server, no loss of privacy or quality. Modfy gives you the capabilities of FFmpeg without having to download it or use the command line, directly in your browser. It’s the first in a suite of optimization and creative video editing tools designed entirely to work in-browser.
