Use a bold square design with generous edges, test it at 16 and 32 pixels, and include both modern PNG links and a multi-size favicon.ico.
Generate a favicon package
Start with one image and get favicon.ico, crisp PNG sizes, an Apple touch icon, and a ready HTML snippet.

Simplify before shrinking
Fine text and thin lines disappear at favicon scale. A strong silhouette, limited colors, and breathing room around the edges survive better across browser tabs and bookmarks.
Generate more than one size
A multi-layer ICO covers traditional browser requests. PNG files serve crisp modern sizes, and an Apple touch icon supports home-screen bookmarks. The generated HTML snippet links the common outputs.
Test light and dark browser chrome
Transparent icons can disappear against some themes. Check the favicon in actual tabs at small size and consider a controlled background when the mark relies on one light or dark color.
