Features

Flexible Radius Control

Adjust the corner radius with a smooth slider or type an exact pixel value. Use the link/unlink toggle to switch between uniform rounding and individual corner control for precise adjustments.

Background Options

Choose between a transparent background (ideal for PNG exports) or a solid color fill for the rounded-off areas. The canvas shows a checkerboard pattern so you can clearly see transparency.

Frequently Asked Questions

How do I make a perfectly circular image?

Click the Circle preset button. This sets the radius to half the smaller dimension of your image, creating a perfect circle. For best results, use a square image.

Why do the rounded corners look black in JPEG?

JPEG does not support transparency. If you export as JPEG with a transparent background, the transparent areas are filled with white. To keep transparent corners, use the PNG format instead.

Can I set different radii for each corner?

Yes. Click the link icon next to the radius slider to switch to individual corner mode. You can then set separate values for top-left, top-right, bottom-left, and bottom-right corners.

What is the maximum corner radius?

The maximum radius is half the smaller dimension of your image. For example, a 400 x 600 image has a maximum radius of 200px.

What image formats can I upload?

You can upload PNG, JPEG, WebP, GIF, and BMP images. You can also paste an image directly from your clipboard.

Is there a file size limit?

Since all processing happens in your browser, there is no server-side limit. However, very large images may be slower to process depending on your device.
