FAQs
Why do width and height swap after a quarter-turn?
A 90-degree or 270-degree rotation turns a wide rectangle into a tall one, or the reverse. A 180-degree rotation keeps the same outer dimensions.
Which inputs do I need for Image Rotator (90°, 180°, 270°) & Horizontal/Vertical Flipper?
Use Original Width (px); Original Height (px); Rotation Angle; Mirror Flip. The built-in examples show how those fields fit together.
What should I check before using this result?
Rotating by 90° or 270° swaps image Width and Height. Keep the original file. Check the saved format, dimensions, page order and content before replacing or sharing a document.
