How to Create a Favicon for a Website

A favicon workflow is stronger than a one-file converter because websites rarely need only one icon output. Browsers, pinned tabs, home screen shortcuts, and manifests all expect slightly different files and sizes.

For a lightweight browser-based product, the highest-value path is turning one clean source image into a multi-size ICO file, a small PNG set, and a ready-to-paste HTML snippet. That keeps the tool practical without trying to become a full design suite.

The useful part is not conversion alone. It is reducing setup friction for a site owner who wants favicon files that work immediately on a new landing page, app site, or marketing site.
