Pixel art circle generator

Drawing a smooth circle on a pixel grid by hand is fiddly, so this tool does the math for you. Set a diameter, choose an outline or a filled circle, pick a color, and download a clean transparent PNG. It's handy for round sprite shapes, UI elements, and planning a circle in a block build like Minecraft. Everything runs in your browser, with no login.

How it works

Set the diameter in pixels
Choose an outline or a filled circle
Pick a color, and for outlines, the ring thickness
Download the circle as a transparent PNG

What you can use it for

Round sprite bases, coins, shields, and UI buttons
A clean circle outline to trace or fill in the pixel editor
Planning circles for Minecraft or other block builds
Consistent circle sizes across a tileset or icon set

Tips

Odd diameters give a circle with a single center pixel; even diameters center on a 2×2 block
For a thick ring, raise the thickness on an outline instead of stacking two circles
Download a few sizes so your circles stay consistent across a project
Drop the PNG into the pixel editor to tweak a pixel or two by hand

FAQ

How do I make a pixel circle?

Enter the diameter you want, choose outline or filled, and download the PNG. The tool plots the roundest pixel circle for that size automatically.

Can I make a filled circle?

Yes. Switch the style to Filled for a solid disc, or keep it on Outline for just the ring.

Is it good for Minecraft circles?

Yes. Pick the diameter you need and use the outline as a block-by-block guide for round towers, domes, and other builds.

Does the PNG have a transparent background?

Yes. Only the circle pixels are colored, so the rest of the image stays transparent and drops cleanly onto any background.
