Edit Pictures Like a Pro on Your iPhone
Although the Photos app on iPhone offers a bunch of options to edit your pictures, it still needs a few more features to make it a pro editing app. Until that happens, you can always try the Photos Toolkit Shortcut. This Shortcut lets you resize, rotate, and flip images like the Photos app, but it can additionally let you create GIFs, combine and overlay two images, and even convert any image to other formats—all that from just one Shortcut.
