Favicon vs Logo, App Icon and Social Preview

The short answer

A favicon identifies a website in browser and search surfaces. A logo is the broader brand asset from which a favicon may be simplified. Apple touch and PWA icons launch saved or installed experiences, while an Open Graph image represents a shared page in social and messaging previews.

These assets should look related, but copying identical pixels into every slot usually creates bad crops, unreadable text, transparent launcher backgrounds, or a social card with no useful context.

Match the asset to the surface

Favicons need a compact square silhouette that survives 16×16. Apple touch icons use a dedicated 180×180 PNG and benefit from an intentional background. Ordinary PWA icons describe the app identity; maskable icons require full-bleed pixels and a protected center for adaptive crops.

Social preview images are wide editorial or marketing compositions, commonly using page-specific imagery and readable text. They are declared through Open Graph or platform metadata, not rel=icon or a web app manifest.

Build one identity system, not one file

Choose a shared color, symbol, or letterform, then adapt its composition. Document the safe area, background behavior, minimum recognizable size, and which master file generates each deliverable.

Keep filenames and metadata explicit. A browser favicon, Apple icon, manifest icon and social image can coexist without ambiguity when every URL, type, size and purpose matches the real file.

Production handoff

Export and inspect favicon.svg, favicon.ico, a raster browser fallback, apple-touch-icon.png, ordinary and maskable manifest icons, and the appropriate social image. Test the favicon at native size and every app icon inside representative crops.

Use the HTML generator for browser declarations, the manifest generator for install assets, and page-level Open Graph tags for social previews. Validate each system separately after deployment.
