Icon Generator — Custom PNG from an Image

Create a custom PNG icon from an image already on your device. Choose a square pixel size, preserve the whole image or crop its center, then add spacing and a background if needed. This tool resizes your supplied artwork; it does not invent a logo or replace a platform-specific app icon workflow.

How to use this tool

1. Choose one PNG, JPEG or WebP image within the displayed limits.
2. Set the output side from 8 to 2,048 pixels and choose fit or center crop.
3. Set padding, background and corner radius; zero radius keeps a square.
4. Generate the icon, inspect its preview and download the PNG.

Formula

Inner side = output side × (1 − 2 × padding / 100); fit scale = min(inner side / width, inner side / height)

Center crop uses the maximum ratio instead. The image is clipped to the inner square, leaving the requested padding on every side. Corner radius is measured against the entire output side; 50% produces a circle.

Example

A 160 × 100 image fitted into a 256 × 256 square with zero extra padding becomes 256 × 160 pixels, leaving 48 pixels above and below. A center crop fills the square and removes equal amounts from the source left and right.
