Also use when the user mentions \"favicon,\" \"app icon,\" \"browser icon,\" \"touch icon,\" \"PWA icon,\" \"favicon sizes,\" \"apple-touch-icon,\" \"favicon.ico,\" \"site icon,\" or \"tab icon.\" For visual system, use brand-visual-generator.\nmetadata:\n  version: 1.0.1\n---\n\n# Components: Favicon\n\nGuides favicon and app icon implementation for brand consistency across browser tabs, bookmarks, mobile home screens, and **Google Search results**. Favicons help users identify sites; missing or incorrect icons hurt trust.\n\n**When invoking**: On **first use**, if helpful, open with 1-2 sentences on what this skill covers and why it matters, then provide the main output. On **subsequent use** or when the user asks to skip, go directly to the main output.\n\n## Initial Assessment\n\n**Check for project context first:** If `.claude/project-context.md` or `.cursor/project-context.md` exists, read it for brand and visual identity.\n\nIdentify:\n1. **Tech stack**: Next.js, WordPress, static HTML, etc.\n2. **PWA**: Is the site a PWA or planning to be?\n3. **Existing assets**: Logo, icon files\n\n## Required Sizes\n\n| Size | Use |\n|------|-----|\n| **16x16** | Browser tabs, standard displays |\n| **32x32** | Retina/HiDPI browser tabs |\n| **180x180** | Apple Touch Icon (iOS home screen); no transparency |\n| **192x192** | Android Chrome home screen, PWA launcher |\n| **512x512** | PWA splash screens, adaptive icons |\n\n**Optional**: 48x48, 96x96, 120x120, 152x152, 167x167, 256x256 for broader coverage.\n\n## Formats\n\n| Format | Use |\n|--------|-----|\n| **SVG** | Modern browsers; scalable; supports dark mode via media queries; lightweight |\n| **PNG** | High-DPI; explicit sizes; easy to generate; required for Apple Touch Icon |\n| **ICO** | Legacy; bundles multiple sizes; fallback for older browsers |\n\n**Recommended**: Provide SVG + PNG fallbacks. Never skip Apple Touch Icon (180x180); iOS shows a generic screenshot without it.\n\n## Google Search (SERP Display)\n\nSee **serp-features** for SERP feature types and optimization.\n\nFavicons can appear in Google Search results next to your site's listings. [Google Search Central](https://developers.google.com/search/docs/appearance/favicon-in-search) requirements:\n\n| Requirement | Guideline |\n|-------------|-----------|\n| **Placement** | Add `<link rel=\"icon\" href=\"/path/to/favicon.ico\">` to **homepage** header |\n| **One per hostname** | One favicon per hostname; `example.com` and `code.example.com` are separate; `example.com/sub-site` shares the same favicon |\n| **Crawlability** | Googlebot-Image must crawl favicon; Googlebot must crawl homepage; do not block either in robots.txt |\n| **Shape** | Square (1:1 aspect ratio); minimum 8x8px; **preferably >48x48px** for quality across platforms |\n| **Stable URL** | Do not change favicon URL frequently |\n| **Appropriate** | No inappropriate content (pornography, hate symbols); Google may replace with default icon |\n| **Timing** | Crawling can take days to weeks; use Search Console URL Inspection to request indexing |\n\n**Supported rel values**: `icon`, `shortcut icon`, `apple-touch-icon`, `apple-touch-icon-precomposed`. **href** can be relative (`/favicon.ico`) or absolute; favicon can be hosted on CDN.\n\n## Implementation\n\n### HTML Link Tags\n\n```html\n<link rel=\"icon\" href=\"/favicon.ico\" sizes=\"any\">\n<link rel=\"icon\" href=\"/icon.svg\" type=\"image/svg+xml\">\n<link rel=\"icon\" type=\"image/png\" sizes=\"32x32\" href=\"/favicon-32.png\">\n<link rel=\"apple-touch-icon\" sizes=\"180x180\" href=\"/apple-touch-icon.png\">\n```\n\n### Next.js\n\nPlace in `/app`: `favicon.ico`, `icon.png`, `apple-icon.png`. Next.js auto-generates tags.\n\n### PWA Manifest\n\nInclude `icons` array in `manifest.json` with 192x192 and 512x512 for maskable icons.\n\n## Best Practices\n\n- **Simplicity**: At 16x16, complex details are illegible; use simplified logo mark; design for brand recognition in SERPs\n- **Consistency**: Favicon should match logo/brand (logo-generator, brand-visual-generator)\n- **Cache**: Use long cache; version for updates (e.g. `/favicon.ico?v=2`)\n- **Tools**: RealFaviconGenerator, favicon.io, or favicons npm package for automation\n- **Test**: Check across browsers, dark mode, and Search Console (favicon may take days to weeks to appear)\n\n## Output Format\n\n- **Size** checklist (16, 32, 180, 192, 512; >48x48 for Google Search)\n- **Format** recommendations (SVG, PNG, ICO)\n- **Implementation** notes per tech stack (homepage header placement)\n- **Google Search** checklist (crawlability, stable URL, appropriate content)\n- **Manifest** (if PWA)\n\n## Related Skills\n\n- **logo-generator**: Favicon typically derived from logo; consistent branding\n- **media-kit-page-generator**: Media kit should include favicon or link to brand assets\n- **brand-visual-generator**: Visual identity; favicon aligns with brand colors and mark\n- **indexing**: Favicon requires crawlable homepage; URL Inspection for indexing\n","tagline":"When the user wants to implement, optimize, or audit favicon and app icons.
