Frequently Asked Questions

Can I make a circular image?

Yes! Set the corner radius to at least half of the smaller dimension of your image. The tool will automatically clamp the radius to create a perfect circle or rounded rectangle.

What is the maximum corner radius?

The maximum radius is half of the smaller dimension of your image. For example, a 200×200 pixel image has a maximum radius of 100px, which produces a perfect circle.

Will my image background be transparent?

Yes, the output is saved as PNG with transparency. The corners become transparent, making it perfect for overlaying on different backgrounds or creating profile pictures.

Is my image uploaded to a server?

No. All processing happens entirely in your browser using the HTML5 Canvas API. Your images never leave your device.
