Frequently Asked Questions (FAQs)
How do I make an image circular?
Upload a square image, and slide the Corner Radius control to its maximum value (or toggle the 'Force Circle' option). The tool will clip the image into a perfect circle.
Can I keep the background transparent around the rounded corners?
Yes. Ensure the background option is set to 'Transparent' and download the image in PNG format. PNG format supports alpha transparency, keeping the corners completely see-through.
Is my uploaded image secure?
Absolutely. Processing is done 100% locally in your web browser. No files are uploaded, saved, or sent to any remote server.
Why is my downloaded image dimensions slightly larger than the original?
If you add a drop-shadow, the canvas size is automatically padded to prevent the soft outer glow of the shadow from being clipped. This keeps the shadow looking smooth and professional.
