Radiator FAQ Matrix
What exactly is a 'Squircle' compared to a normal rounded corner?
A Squircle is a mathematical hybrid between a square and a circle (a superellipse). It creates smoother, more premium-looking rounded corners than standard CSS border-radius, often seen in high-end iOS design.
Is it safe to upload my brand assets to this tool?
Yes. RapidDocTools uses 100% client-side rendering in 2026. Your images are never uploaded to our servers; all cropping, rounding, and padding happen instantly in your browser's memory.
Can I set individual corner radii for my design?
Yes. Our workbench allows you to unlock the corners and set a unique rounding value for each of the four corners independently, enabling creative asymmetrical layouts for professionals.
