There’s a lot of power on that markup toolbar for image editing! Left to right, the icons let you access selection type, “instant alpha” (color correction), sketch, draw, add geometric object, add text, add a signature (if you have that set up already, more useful on PDF documents than photos), adjust color, resize (the tiny box with the arrows on the top left and bottom right), change line width for sketch and draw tools, change frame size, color, and font adjustments for the add text feature.

But it turns out that the program offers so much more, from supporting you filling in PDF forms to adding a password to keep your PDF docs secure, editing, cropping, even adjusting colors on a photo or any other graphical file on your system. I’m talking about Preview, a program that most people associate with letting you read PDF documents.
