Frequently asked questions
- How do I rotate an image 90 degrees?
- Select 90 degrees from the rotation presets and click process. The image is rotated clockwise. For counter-clockwise, use 270 degrees.
- Can I straighten a crooked photo?
- Yes. Use the custom angle rotation to enter the exact degree of correction needed. For scanned documents, even 1-2 degrees of correction makes a visible difference.
- What is the difference between rotate and flip?
- Rotating turns the image around its center by a given angle. Flipping mirrors it along an axis, creating a mirror image horizontally (left-right swap) or vertically (top-bottom swap).
