About Border Radius Previewer

The Border Radius Previewer is a powerful visual tool designed to help developers and designers master CSS rounded corners. Instead of guessing pixel values, you can visually drag sliders to shape your element exactly how you want it. Whether you need a simple rounded button or a complex organic shape, this tool provides immediate visual feedback. It supports both uniform radius (all corners linked) and individual corner control for asymmetrical designs. Once you are happy with the shape, simply copy the generated CSS code and paste it into your project.
