Favicons are the small icons that display in browser tabs, bookmarks, and mobile home screens. Modern websites require a bundle of different sizes.
Core Favicon Assets
1. favicon.ico: Legacy file containing 16x16 and 32x32 sizes for standard browser tabs.
2. apple-touch-icon.png: A 180x180 square icon used by iOS devices.

Exporting a complete package with a preconfigured web app manifest ensures your site displays correctly on all devices.
