Frequently Asked Questions

Why is PNG recommended for rounded corners?

PNG supports transparency, so the rounded corners appear truly transparent when placed on any background. JPEG does not support transparency, so the corners are filled with your chosen background color instead.

What radius should I use?

For social media thumbnails and app icons, 16–32 px works well. For a fully circular result, set the radius to half the shortest dimension of your image.

Can I process multiple images at once?

Yes. Drop a batch and the same radius and output settings are applied to every image.
