How to safely convert photo file format?

I want to delete the metadata by using a command tool called mat2 to delete the metadata. However, I tried to delete it, but I couldn’t delete it because svg and bak file formats are not supported. So I want to safely convert it to png or jpeg or any other supported file format. What is the best way to do it? I think it’s safer to convert with commands, but how about it?
