What is a favicon?

A favicon is the small icon that represents your site in browser tabs, bookmarks, and shortcuts — a quick visual way to identify the site.

Why do I need multiple sizes?

Browser tabs (16, 32px), desktop bookmarks (48px), iOS home screen (180px, apple-touch-icon), and Android/PWA manifests (192, 512px) each expect different resolutions, so it's best to prepare several sizes together.

Why do I need an ICO file?

ICO is a classic icon format that can bundle multiple resolutions in one file. Older browsers and some environments request favicon.ico at the site root directly, so it's still widely provided alongside PNGs.

Privacy & safety

Loading, resizing, assembling the ICO, and downloading all happen entirely in your browser — files are never uploaded or stored on a server.
