Frequently Asked Questions

How do I add rounded corners to an image?

Upload your image, then use the corner radius slider to set how rounded you want the edges. You can also use the preset buttons (Subtle, Medium, Round, Full) for quick adjustments. Click Download to save your image with rounded corners.

Can I control the corner radius precisely?

Yes. The radius slider lets you choose any value from 0 (sharp corners) to 50% of the shorter side (fully rounded). The live preview updates instantly as you drag.

Will the corners have a transparent background?

When you download as PNG, the rounded-off corner areas are fully transparent. If you choose JPG or WebP, the corners are filled with white since those formats don’t support transparency.

Can I use this for app icons?

Absolutely. iOS app icons use a specific rounded rectangle (superellipse) shape. Use the Round or Full preset to approximate the look, or dial in the exact radius you need.

Is this the same as CSS border-radius?

Similar concept. CSS border-radius rounds HTML elements on screen but doesn’t modify the image file itself. This tool applies rounded corners directly to the image pixels, so the result looks rounded everywhere — email, social media, print.

What image formats are supported?

You can upload PNG, JPG, JPEG, WebP, BMP, and GIF images. Output formats include PNG (transparent corners), JPG, and WebP with adjustable quality.

Will rounding corners reduce image quality?

No. The tool crops and clips the original pixels at full resolution. For PNG output the quality is lossless. For JPG and WebP, you control quality with the slider.
