Frequently Asked Questions
Does rounding image corners reduce photo quality?
No. The rounding algorithm renders anti-aliased curves directly on your photo's full native resolution and exports as a crisp, lossless 32-bit PNG.
Can I round only specific corners (e.g. only top corners)?
Yes! Use the Individual Corner checkboxes to toggle rounding on Top-Left, Top-Right, Bottom-Left, or Bottom-Right independently.
How do I make a circular profile picture avatar?
Upload your picture and click the '⭕ Full Circle' preset button. The tool automatically centers and rounds the photo into a 50% circle radius with transparent edges.
Are my images uploaded to any server?
Never. All image processing runs 100% locally in your web browser via HTML5 Canvas. Your photos never leave your device.
