I have a better solution that I found out by accident.
So you initiate the sharing, right, then before you select the Messenger app (or whichever app that doesn’t handle webp), you click the little edit button on the image above the shareable apps. That brings up cropping and other adjustments. But from here, you can just hit the big Share button immediately to share the image practically losslessly (without cropping mistakes and such). It brings up the share thing again but this time the image will be in a shareable format, presumably PNG(?).
I screen shot and crop every meme i want to share from Lemmy. It is tedious.
