Create six standard PNG favicon sizes locally from one image.
<link rel="icon" type="image/png" sizes="32x32" href="favicon-32x32.png">
A favicon should remain recognizable at very small sizes. Simple shapes, strong contrast and generous spacing usually work better than detailed photographs or long text.
The generated PNG sizes cover common browser, shortcut and app-icon needs. Browsers may cache an old favicon, so use a new filename or clear cache after updating a live site.
Use a square PNG with a clear symbol and enough padding around the edges.
Browsers and devices select different files depending on display density and context.
It creates standard PNG sizes; use the supplied site icon setup or a dedicated ICO workflow if required.
