What Is Image Circle Crop?

An image circle cropper cuts your image into a perfect circular shape, automatically centering the crop. The tool takes the shortest dimension as the circle diameter, ensuring a perfect circle. Areas outside the circle become transparent or a solid color of your choice. This is the go-to tool for circular profile pictures, round avatars, and circular design elements. Output is saved as PNG to maintain transparency.

Why Use Image Circle Crop?

• Perfect circle crop from image center
• Choice of transparent, white, or black background

Technical Guide

Circle cropping uses the Canvas API arc and clip methods. The shortest dimension determines the circle diameter. The canvas is set to this square dimension. For non-square images, offsets are calculated to center the source region. A circular clipping path is created using ctx.arc(), then ctx.clip() is called. The source image region is drawn within this circular clip. If a background color is chosen, it is filled before clipping.
