Sometimes, I want to use closed-source applications on Linux. While I can usually find a Flatpak version, sometimes only a Snap package is available.

For such cases, I've created a simple script https://github.com/izissise/snap2flatpak. It automatically downloads the Snap archive from the Ubuntu server and repacks it as a Flatpak.

I haven't tested it with many apps, so you might need to tweak it, especially to choose the correct Flatpak runtime.
