Rotate a rectangular photo by anything other than a clean 90° step and its corners push past the original frame boundaries. Some online rotators just crop that overflow away, quietly losing part of the image.
Rotate image without cropping corners
This image rotator calculates the full rotated bounding box and expands the canvas to fit it — nothing outside the original frame gets clipped, at any angle.
Straighten a tilted photo online with a free-angle slider
Beyond the 90°/180° buttons, a -45° to 45° slider lets you nudge a tilted horizon level — a feature plenty of "rotate image" tools skip in favor of 90°-only steps.
PNG transparent corners, or JPG with a fill color
Since a rotated rectangle doesn't fill a rectangular canvas, you choose: PNG leaves the new corners transparent, JPG fills them with a solid background color.
