Round the Corners of an Image
Give any image soft, rounded corners and download it as a transparent PNG (or WebP). Drag the radius slider from a subtle curve all the way to a pill or circle, and choose pixels or a percentage. Everything runs in your browser, so the image never leaves your device.
How to round the corners of an image
- Drop an image in, or click to browse.
- Set the corner radius with the slider, in pixels or percent.
- Download the result as a transparent PNG or WebP.
Examples
Soften a thumbnail
A 400x400 product image, radius 48px
The same image with smoothly rounded corners on a transparent background
Frequently asked questions
Is my image uploaded anywhere?
No. The rounding happens entirely in your browser with the Canvas API, so the image never leaves your device.
Why should I export as PNG or WebP?
Rounded corners need transparency so the area outside the curve shows through. PNG and WebP support transparency; JPEG does not, so it would fill the corners with a solid color instead.
Can I make the image a circle?
Yes. Set the radius to 100% (or to half the shorter side in pixels) and a square image becomes a circle. For dedicated avatar exports, try the circle crop tool.
Does it reduce quality?
No pixels inside the rounded area are changed; only the corners are clipped away. Exporting to PNG is lossless.
