About Flip Image Horizontally
When is it useful? Flip Image Horizontally mirrors a picture from left to right, like looking in a mirror. Use it to fix selfies where writing on clothes or signs appears back-to-front, to make a person or product face the other way in a design, or to prepare iron-on and T-shirt transfer prints that must be printed mirrored.
Good to know: flipping is not the same as rotating — the top stays at the top and only left and right swap places. The picture keeps its width and height, and the flip itself loses no quality. The result is saved as a new PNG file, and photo details such as camera and GPS data are not copied. To turn a picture upside down instead, use Flip Image Vertically.
