How to convert .avif image files with Directory Opus?

I can't get the Convert... dialog to work with .avif files. Save as JPEG, PNG, etc. also don't work.

How do I convert .avifs with DOpus?

Out of the box, Opus can read avif but can’t write them.

You could create a button that does the conversion using a tool like ImageMagick:

@nodeselect
magick.exe convert {filepath$} {filepath|ext=avif}
