Rotate 90

Transform

Rotates an image by exactly 90°, 180°, or 270°. Pixel-perfect with no interpolation.

Rotate 90 performs exact right-angle rotations without any resampling or quality loss. Choose from 90° clockwise, 180°, or 90° counter-clockwise. Because the rotation is always a multiple of 90°, every pixel maps perfectly to its new position with no blurring or anti-aliasing artifacts.

Use this instead of Transform’s rotation when you need a precise quarter-turn. Transform uses interpolation for arbitrary angles, which softens the image slightly. Rotate 90 keeps every pixel intact.

Default: 90° CW

Rotation increment

• 90° CWRotate 90 degrees clockwise.
• 180°Rotate 180 degrees, equivalent to flipping both axes.
• 90° CCWRotate 90 degrees counter-clockwise.

Usage Tips

• Use for rotating photos taken in portrait orientation back to landscape (or vice versa).
• Combine with Mirror for all eight possible orientations of an image.
• Prefer this over Transform when you only need 90° increments, since there is no quality loss.
