FAQ

Which image formats can I round?

The tool supports PNG, JPEG, and WebP images up to 10MB each.

How do I add rounded corners to an image?

Upload an image, then drag the Corner radius slider and preview the result on the right. Choose a transparent, white, or custom background and a PNG, JPEG, or WebP output format, then click Download image.

What corner radius should I use?

The larger the radius, the rounder the corners. Within the limits of the image size, a radius equal to half the shorter side produces a full circle. Adjust it while watching the preview rather than always using the maximum.

How do I export a transparent background?

Choose Transparent as the background and export as PNG or WebP. JPEG does not support an alpha channel, so transparent areas cannot be preserved.

Should I choose PNG, JPEG, or WebP?

Choose PNG for a transparent background or lossless quality, WebP for a smaller file that still supports transparency, and JPEG for maximum compatibility when transparency is not needed.

Are my images uploaded to a server?

No. Upload, preview, rounding, and download all happen locally in your browser. Images are not sent to a server, and the current image is cleared when you close or refresh the page.
