• Web UI Components: Prepare product cards, testimonials, and screenshot mockups that match modern CSS border-radius guidelines.

• Digital Presentations: Soften screenshots and diagram illustrations before inserting them into pitch decks and slides.

Frequently Asked Questions

Can I save my image with transparent corners?

Yes. When you choose PNG format with a transparent background, the cut areas outside the rounded corners remain fully transparent. This makes the image ready for any web background.

How do I make an image completely circular?

If your starting image is a square (equal width and height), setting the radius slider to 50% produces a perfect circle. For rectangular photos, 50% produces a smooth pill or stadium shape.

Does rounding corners reduce image quality?

No. Processing occurs locally at full canvas resolution. The tool clips original pixel data and exports clean, anti-aliased curves without compression artifacts.
