Frequently Asked Questions
What's the difference between this and the Circle Crop tool?
While our Circle Crop tool creates perfect circular images, the Rounded Corners tool offers rectangular images with adjustable corner radius. This gives you flexibility for designing UI elements, cards, thumbnails and other rectangular components with smooth corners.
How much control do I have over the corner radius?
Complete control! You can adjust corner radius from 0px (sharp corners) up to half the width of your smallest dimension. The tool shows both pixel values and percentage for reference, helping you achieve consistent rounded corners across different sized elements.
Can I create different aspect ratios with rounded corners?
Absolutely! You can select from common presets like square (1:1), landscape (4:3), widescreen (16:9), portrait (3:4), and mobile (9:16), or create completely custom dimensions by specifying exact width and height values.
Does this tool maintain image quality?
Yes, our tool is designed to maintain the highest possible image quality. We offer a high-quality export option that preserves all details in your image. The rendering engine creates smooth anti-aliased corners that look professional at any resolution.
