Why Use This Image Corner Rounder?

Browser-Based Editing

How this Image Corner Rounder works

The Image Corner Rounder applies rounded corners to your image directly in the browser. After you upload a file, the tool draws the image on an HTML canvas, creates a rounded rectangle mask, and clips the image to that shape. The radius slider controls how soft or strong the corners look, from a small polish to a fully rounded badge style. You can keep the background transparent for PNG overlays, stickers, profile graphics, and web assets, or choose a solid color when the image will sit on a fixed background. The original image is not uploaded or modified. The final preview is rendered as a new PNG that you can download. This makes it useful for product cards, thumbnails, avatars, app mockups, and quick design cleanup.

Frequently Asked Questions

Will this tool upload my image?
No. The image is processed with canvas in your browser. It is not sent to a server.
Can I make the background transparent?
Yes. Keep the transparent option selected and download the result as a PNG with rounded transparent corners.
Why is the download a PNG file?
PNG supports transparency, which is needed for clean rounded corners on websites, thumbnails, and profile graphics.
Can I use a solid background instead of transparency?
Yes. Choose the solid color option and pick the background color that matches your page or design.
Does rounding corners reduce image quality?
The tool redraws the image at its original pixel size. The visible content remains sharp, but the output format is PNG.
What radius should I use for avatars?
For square avatars, use a radius close to half the image size for a circle. For softer cards, use a smaller radius.
Can I round only one corner?
This version applies the same radius to all four corners, which is the most common need for web and social graphics.
Does it work with screenshots?
Yes. Screenshots, photos, product images, logos, and browser-supported image formats work well.
