Actually, that's least of our problem, some time google intentionally won't align it to center, for example, play button.so placing thing center won't fix it. but this plugin offsets the icon when converting. I've been asking about it since 2017 either we must be missing something huge otherwise developer would have answered, check my issue here #121 and a similar issue here #100
