Rotate an image by 90, 180, or 270 degrees
Add one or more images, pick the angle, and download. The preview shows the turned result and the export keeps the original format. Right-angle rotations are exact, so the image stays as sharp as the source.
90°turns the image a quarter clockwise and swaps width and height.180°flips it upside down and keeps the original dimensions.270°turns it a quarter counter-clockwise (a quarter clockwise from the other side) and also swaps width and height.
Rotate a batch or a single image
The rotate-all control applies the same angle to every loaded image, which is the fast path for a folder of photos shot in the wrong orientation. Each image also keeps its own angle, so you can fix one sideways shot in a set without touching the others, then export each from its card or all at once.
Rotating vs flipping
Rotating turns the image; it does not mirror it. Text and faces keep their normal handedness after a rotation, where a flip would reverse them. Reach for rotation when a photo was captured sideways or upside down; reach for a flip only when you actually want a mirror image.
Why dimensions change at 90 and 270
A 90° or 270° turn maps the original width onto the new height and the original height onto the new width, so a 1600 × 900 landscape becomes 900 × 1600 portrait. A 180° turn keeps the same dimensions because it rotates around the center. This matters when the rotated image has to fit a fixed frame, since the aspect ratio inverts on a quarter turn.
How rotation works
The image is drawn onto a canvas sized for the target angle, with the canvas transform set to the rotation so pixels land in their new positions. Right-angle turns move whole pixels without interpolation, which is why no detail is lost. Everything runs in the browser, so nothing is uploaded.
