Enter any domain and instantly see its favicon at every standard size — 16px, 32px, 64px, 128px, and 256px. Check if your icon stays crisp in browser tabs and bookmarks.

What is a Favicon?

A favicon (short for "favourite icon") is the small icon that appears in browser tabs, bookmark lists, browser history, and search engine results. It's typically a 16×16 or 32×32 pixel image defined by a <link rel='icon'> tag in your HTML head. A well-designed favicon reinforces brand recognition even when users have dozens of tabs open.

Favicon Best Practices for Indie Makers

  • — Use a square canvas — non-square favicons get cropped unexpectedly in some browsers.
  • — Keep it simple — your full logo won't work. Use just an icon or first letter.
  • — Avoid text — even at 32px it becomes unreadable.
  • — Use a solid background or transparency — not gradients that blur at small sizes.
  • — Test on both light and dark browser themes — your icon needs contrast on both.
  • — Provide an SVG favicon for perfect sharpness at any resolution: <link rel='icon' type='image/svg+xml'>
