Flip vs. Rotate: What's the Actual Difference?

Flip and rotate get confused constantly because both change an image's orientation — but they're solving different problems, and using the wrong one produces a subtly wrong result (or, with text in frame, an obviously wrong one).

The Flip Image tool on keptlocal mirrors an image horizontally or vertically, entirely on your device.

The actual difference

Rotation turns an image around a center point, like spinning a photo on a table. Every point moves along a circular arc; the image's basic left-right, top-bottom relationships stay intact — if a person's left hand was on the viewer's left before a 90° rotation, it's now on the viewer's bottom, but their body is still built the same way.

Flipping mirrors an image across an axis, like reflecting it in a mirror or in water. A horizontal flip swaps left and right — anything on the left edge moves to the right edge, and vice versa. A vertical flip swaps top and bottom the same way. Critically, flipping reverses handedness: a flipped photo of someone writing with their right hand shows them appearing to write with their left. Text becomes backwards and unreadable. This is the tell that distinguishes the two operations at a glance — rotated text is legible but oriented differently; flipped text is mirror-reversed.

When you actually need to flip

• Mirrored selfies. Many phone front cameras display a mirrored preview while you're framing the shot (so it feels like looking in a mirror), but save the actual file un-mirrored — meaning the saved photo can look "backwards" compared to what you expected on screen. A horizontal flip corrects this.
• Scanned images fed in backwards. A photo or document scanned face-down instead of face-up (or reversed in some other way specific to the scanner) can come out mirrored.
• Intentional mirrored design elements. Design work sometimes calls for a genuinely mirrored version of an asset — a symmetric pattern, a reversed icon for a different layout direction.

If your actual problem is that the image displays sideways or upside down — not mirrored — you want Rotate, not Flip.

Privacy: what happens to your photo

Flipping happens on an HTML5 canvas in your browser — your photo is never uploaded. Open DevTools → Network while using the tool and you'll see no outbound requests.
