First time on a Mac?

GrabNConvert is not notarised by Apple yet, so macOS asks you to confirm once in System Settings. It takes about a minute.

How to open it

Not sure which Mac you have? Apple menu → About This Mac: "Apple M1/M2/M3/M4" is Apple Silicon, "Intel Core" is Intel. By downloading you agree to the licence. Download only what you made, what is free to download, or what you have permission to download. Respect the site's terms and the creators' rights.

First launch.

GrabNConvert is an independent app and not yet signed with Apple's or Microsoft's paid certificates, so each system asks once.

Changelog

What changed in each version, in plain words.

GrabNConvert is proprietary software; the End User Licence Agreement is also shown by the installer. It ships FFmpeg and FFprobe (GNU GPL v3), aria2 (GNU GPL v2 or later), yt-dlp (Unlicense), Deno (MIT) and whisper.cpp (MIT), built from their official source without changes, and runs them as separate programs. Their full licence texts and the complete list of components are in the third-party notices.

As the GPL requires, the complete source code of the FFmpeg and aria2 builds is available, and we send it on request. The open-source licences page lists every engine with its exact version and source link.
