How Flip Image Works

Flip Image mirrors your picture across an axis by reversing the order of pixels along one dimension of the canvas. Horizontal flip reverses left and right: every column of pixels swaps position with its mirror on the opposite side, so whatever was against the left edge ends up against the right edge and vice versa. Vertical flip does the same thing along the other axis, reflecting rows of pixels across a line through the vertical middle of the image, so the top and bottom trade places. Because both operations only reorder existing pixels — nothing is interpolated, blurred, or resampled — a flipped image is pixel-for-pixel as sharp as the source; any quality loss you might notice afterward comes from re-encoding to a lossy format like JPEG on export, not from the flip itself. Transparency and color data survive untouched too — a PNG with an alpha channel keeps its transparent regions in their newly mirrored positions. The two directions are independent and combinable: applying Horizontal then Vertical (or the reverse order) produces a 180-degree point mirror, equivalent to rotating the image a half-turn. Applying the same direction twice returns the image to its starting orientation. It's worth being clear about what flip is not. It is not a rotation tool — an image that's sideways because it was captured in portrait orientation needs to be turned 90 degrees, and flipping it instead leaves it sideways and now also mirrored. It doesn't correct perspective, skew, or lens distortion. And because it mirrors the entire canvas as one piece, any text, watermark, or logo inside the picture gets mirrored along with everything else and comes out reading backward — flip has no concept of "just this object" or "just this layer."
