About this tool

The radius is a percentage of the shorter side, so the look stays consistent across images of different sizes. Circle mode crops the center square first. Output is PNG (or WebP) to keep the corners transparent; choose JPG with a background color if you need a smaller file.

Frequently asked questions

Why is my image saved as PNG?

JPG can’t store transparency, so rounded corners would turn white or black. PNG keeps them see-through.

How do I make a circle profile picture?

Pick Circle. The tool crops the middle square and masks it to a circle.

Can I add a border too?

Yes, run the result through the Add Border tool.

Are my files uploaded to a server?

No. ConvertBrightly processes files with JavaScript inside your browser. Nothing is sent over the network, and the files disappear when you close the tab. You can even disconnect from the internet after the page loads.
