Begin with recognition, not decoration

Choose one brand signal: a letterform, distinctive silhouette, or reduced symbol. Multiple symbols become visual noise in a browser tab.

Build an optical safe zone

Leave roughly 10–15% breathing room around the core mark. Circle masks and rounded app-icon crops can remove corners, so keep essential content near the center.

Q&A

Questions, answered

How many colors should a favicon use?+

One foreground and one background color is a strong starting point; add complexity only when it remains readable.

Can I use my full logo?+

Use the logo mark or initials. Full wordmarks are rarely legible in a tab.
