Mac Users: Extract Frames from Animated GIFs with Preview.app
Animated GIFs are kind of a relic these days, but when you need to crack one open and get at its individual frames, you might think Photoshop is that way to go. Alas, Photoshop doesn’t support animated GIFs (any more).
But! It turns out Preview.app does. You just open the GIF and drag the frames right out of it. Handy.
