What shapes can the rounded-corner tool make?
It supports rounded rectangles and perfect circles, with 0%-50% radius control: 0% is square, 25% is a typical rounded corner, 50% approaches a circle. Output is transparent-background PNG.
How do I make a circular avatar from a photo?
Upload the image and choose Circle mode. The tool crops around the image center and outputs a transparent circular avatar — ideal for WeChat, social profiles and app avatars in one step.
Can the corner radius be adjusted precisely?
Yes, a continuous 0%-50% slider: 0% square, 50% circle, with middle values for rounded cards, button assets and product displays.
Is the rounded image background transparent?
Yes. Output is transparent PNG — the area outside the rounded shape is fully transparent, so it layers cleanly on any background without white or black edges.
Is online rounded-corner processing safe?
Safe. Processing runs entirely in your browser; images never upload, suitable for personal photos, brand assets and unpublished designs.
What is the rounded-corner effect best for?
WeChat/QQ avatars, app icons, e-commerce cards, PPT assets, UI elements and social media covers needing rounded or circular treatment.
Are there limits on free use?
No. Free, no registration, unlimited, no watermark. JPG/PNG/WebP uploads output high-quality transparent PNG.
Which upload formats are supported?
JPG, PNG, WebP and other common formats. Animated GIFs process as a static frame; transparent PNG input keeps its alpha.
