What is Rounded Corner Image Generator?

Rounded Corner Image Generator is a tool for applying rounded corners to an image and saving the result as PNG. After you upload an image, you can adjust the radius with a slider and review the preview before downloading.

It is useful for icons, thumbnails, card images, and other assets that need rounded corners. All processing happens in the browser.

How to Use

1. Upload an image.
2. Adjust the Corner Radius slider.
3. Review the preview.
4. Download the result as PNG.

The preview also shows the image dimensions, so you can confirm the result without changing the original resolution.

What You Can Adjust

Corner Radius

You can set the radius from 0px up to the current maximum. The maximum depends on the uploaded image size and is limited to half of the shorter side.

For example, a 200 × 300px image can use a maximum radius of 100px.

Use Cases

• Rounding profile images or icons
• Preparing thumbnails or card images for a website
• Creating rounded assets for UI mockups
• Making quick visual adjustments without opening an image editor

Things to Keep in Mind

• The output format is always PNG
• The rounded corners are saved as transparent areas
• If you need a background color behind the rounded image, you will need to add it after downloading
• The original image dimensions are preserved
