I am making a nice GUI app that can convert files to any media file type.
This can be useful if your game engines support only certain file types for audio, For example in the #godotengine .ogg is faster than .mp3.
You can also bulk convert many png images to .webp format to host them on your website more efficiently.
And many more.
