## How to use round image corners

2. Create the result and inspect its details.
3. Download your file without creating an account.

## A practical example

On a 400 × 200 image, a 100-pixel radius is the maximum useful radius. The middle pixels keep their original colors.

## Frequently asked questions

Are my files uploaded?

No. This utility runs in your browser. Your photos and settings are not sent for processing.

What should I check before using the output?

The outside corners become transparent, not white. Some publishing platforms flatten transparency onto their own background.
