Why Convert to MP4?

MP4 (H.264) is the most universally supported video format. It works on virtually every device, browser, and platform with excellent compression and streaming support.

How it works

CookFile processes your video directly on your device rather than uploading it to an external server. This ensures that your private videos stay private, and it saves you time by avoiding long upload wait periods.
