Of the 6 (?) social networks I post to, I’m certain my Mastodon followers display the greatest technical eptitude. Technical Q: If I wanted to resize the canvas of a batch of images (not resize the images, just add on, say, 200 pixels plain white space to the bottom of each), and then add the same text to all images, is there a tool or app that would do that for me? Resources I have: I pay for Canva, but can’t see how to do it. I have a Mac / iPad. Procreate does it, but individually. Thank you!
