How do I round the corners of a screenshot?

Set the corner radius to your desired value (e.g., 12px for subtle rounding, 24px for more pronounced). You can set each corner independently if you want rounded corners only on specific sides.

Can I add a drop shadow to an image?

Yes. Enable the shadow option and configure the blur radius, offset (X/Y), and shadow color. This creates a soft shadow behind the image, making it appear elevated above the page.

Does adding a border change the image dimensions?

Yes. The border is added around the outside of the image, increasing the total dimensions. A 1000x800 image with a 20px border becomes 1040x840.
