Meta images are important when sharing your content online – the image shows up on your friends’ and followers’ feeds and will help them decide if they should visit your page.

The challenge
The thing is: these images should have the correct size. Facebook and Twitter don’t mind which image you’ll feed them, though; they will happily crop and resize anything they will be fed.
However, that is not always in your best interest. If you have podcast artwork that is a square image, for example, you will notice it will be horribly cropped:

The solution: an iOS shortcut that overlays the image of your choice on top of a transparent PNG of just the right size. This way, instead of cutting pixels from your image, additional invisible pixels are added:
