Overview
Introduction
This tool crops an icon into a circular, avatar-style shape, entirely in your browser, ready for any UI that displays round icons or profile pictures.
It's the same circular-mask operation used by the site's general PNG round creator, applied here to icon-sized assets.
What Is Round Icon Creator?
A client-side icon rounding tool that reads an uploaded icon's pixel data, center-crops it to a square based on its smaller dimension, and clears every pixel outside the inscribed circle to full transparency.
The result is a square canvas with a circular visible area, ready to display as-is in any UI that doesn't itself apply a border-radius mask.
How Round Icon Creator Works
The tool first determines the crop size as the smaller of the icon's width and height, then extracts a centered square region of that size from the original icon.
For every pixel in that square, it measures the distance from the square's center; pixels beyond the circle's radius have their alpha forced to 0, while pixels inside keep their original color and alpha.
When To Use Round Icon Creator
Use it to prepare an icon or logo mark for a UI element that displays circular icons, like a profile picture, chat avatar, or round app badge.
It's also useful for quickly previewing how a square icon will look once a design system's circular mask is applied.
Often used alongside Square Icon Creator and Icon Outline Adder.
Features
Advantages
- Runs entirely client-side; the uploaded icon is never sent to a server.
- Handles non-square icons automatically via a centered square crop.
- Produces a ready-to-use transparent-background circular icon.
Limitations
- The circular edge is hard-cut rather than anti-aliased, so it can look slightly jagged at small display sizes.
- Center-cropping a very wide or tall icon can trim important content near the edges of its longer dimension.
Examples
Best Practices & Notes
Best Practices
- Center your icon's important content before uploading, since edges near the longer dimension get cropped.
- Use the Square Icon Creator first if you'd rather pad than crop a non-square icon.
Developer Notes
The pure crop-and-mask math lives in a lib function that thinly re-exports the shared circular-mask function (also used by the general-purpose PNG round creator) under this icon-specific name, since an icon is just a PNG once uploaded and the underlying distance-from-center calculation is identical.
Round Icon Creator Use Cases
- Preparing a logo mark for a circular profile picture slot
- Creating round app badges or chat icons
- Quickly previewing a square icon's appearance under a circular mask
Common Mistakes
- Uploading a wide or tall icon without centering its important content first, which gets trimmed by the square crop.
- Expecting a soft, anti-aliased circular edge — the mask is a hard cutoff based on pixel distance.
Tips
- Pad your icon to a square with extra margin first if you want to avoid cropping any content during the round.
- Combine with the Icon Shadow Adder afterward for a rounded icon with a soft drop shadow.
