FAQ

How do I add rounded corners to an image online?

Upload your image to the tool, drag the slider or type a value to adjust the radius (in pixels or percentage). When you're happy with it, export with one click and get a perfectly rounded image.

How do I turn a square image into a circle or remove sharp corners?

This is one of the most popular features. Simply max out the radius or select the 'Circle' preset and your image becomes a perfect circle. With transparent PNG export, it's ideal for social media avatars or app icons.

Do rounded corner images support transparent backgrounds?

Absolutely. We recommend exporting in PNG format to keep the area outside the rounded corners transparent, so you can easily layer the processed image over any background or design.

Can I set the exact size of the rounded corners?

Yes. Beyond the quick presets (small, medium, large), you can enter an exact pixel or percentage value to define the radius, perfectly matching any UI design guideline or e-commerce platform image requirements.

How can frontend developers preview iOS icon rounded corners or CSS border-radius effects?

Simply upload an image and enter a pixel value (like typical iOS corner parameters) to preview the effect in real time. Once done, export the HD image for design mockups or dev reference, no need to write CSS manually.

Does rounding corners compress the original image quality?

No. Processing happens losslessly right in your browser. Only the edges are smoothed; colors, sharpness, and details remain completely intact.
