What is a favicon?
A favicon is the small icon a browser shows in the tab, bookmarks, and history next to a page's title. It is usually a square image, commonly 16x16, 32x32, or 512x512 pixels, saved as an .ico or .png file. A clear favicon helps people find your tab among many that are open.
What size a favicon needs
Browsers display favicons small, but modern sites supply a larger square, often 512 by 512, and let the browser scale it down. A simple, high-contrast mark reads better than fine detail at tab size.
How to make one
Start from a square logo or symbol, resize it to a clean square, and export it. Keep the design bold so it stays recognizable when shrunk to 16 pixels.
