Turn sideways photos upright, or mirror an image. Works on many images at once.
Rotating turns the whole picture around its center in 90° steps, like turning a printed photo on a table. Use it for photos taken sideways.
Flipping mirrors the image. A horizontal flip swaps left and right, which is useful for selfies and for facing game characters the other way. A vertical flip swaps top and bottom.
Rotating in 90° steps never loses quality: the pixels are only moved, not recalculated. Save as PNG to keep the result completely lossless.
