FAQ
How to set the corner radius?
Corner radius is set as a percentage, ranging from 0% (sharp corner) to 50% (completely circular). You can precisely adjust using the slider, or use preset buttons to quickly select common corner sizes.
Will the rounded corners change the image content?
No. The rounded corner effect only changes the four corners of the image into arcs, without cropping or changing the main content of the image. The corner areas will become transparent (PNG format) or white (JPEG format).
What output formats are supported?
Processed images are output in PNG format to preserve the transparent background of the rounded corners. If you need other formats, you can use the format conversion tool.
Are the corners proportional?
Yes, the corner radius is calculated as a percentage of the shorter side of the image, ensuring consistent curvature for all four corners without distortion.
