- 16x16: Browser tab icon (classic size).
- 32x32: Taskbar and Windows shortcut icon.
- 48x48: Windows site icon.

Frequently Asked Questions
What format should I use for favicons?
PNG is widely supported and recommended for modern browsers. For maximum compatibility, include both a 32x32 PNG and a multi-size ICO file. SVG favicons are emerging but not yet universally supported.
How do I add a favicon to my website?
Add a <link rel="icon" href="/favicon.png" type="image/png"> tag in your HTML <head>. For multiple sizes, add separate link tags with sizes attributes.
