Favicon Gen

# Favicon Generator

Generate a complete favicon package from a logo, initials, or brand colours. Produces all required formats and HTML integration code.

## Workflow

### Step 1: Choose Your Approach

```
Have a logo with an icon element?
 YES -> Extract icon from logo
 NO  -> Have text/initials?
         YES -> Create monogram favicon
         NO  -> Use branded shape
```

### Step 2: Create Source SVG

**Extracted icon** — copy icon paths from logo, centre in 32x32 viewBox, simplify for small sizes.

**Monogram** — use a template from `assets/`:
```xml
<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 32 32">
  <circle cx="16" cy="16" r="16" fill="#0066cc"/>
  <text x="16" y="21" font-size="16" font-weight="bold"
        text-anchor="middle" fill="#ffffff" font-family="sans-serif">AC</text>
</svg>
```

**Branded shape** — circle (universal), rounded square (modern), shield (security), hexagon (tech).

SVG templates available in `assets/` directory.

### Step 3: Generate All Formats

Requires ImageMagick (`convert` command). Install if needed: `brew install imagemagick` (macOS) or `apt install imagemagick` (Linux).

```bash
# ICO (16x16 + 32x32)
convert favicon.svg -define icon:auto-resize=16,32 favicon.ico

# Apple Touch Icon (180x180, SOLID background — transparent = black on iOS)
convert favicon.svg -resize 180x180 -background "#0066cc" -alpha remove apple-touch-icon.png

# Android/PWA icons
convert favicon.svg -resize 192x192 icon-192.png
convert favicon.svg -resize 512x512 icon-512.png
```

**No ImageMagick?** Use https://favicon.io to convert from the SVG instead.

### Step 4: Create Web Manifest

Copy and customise `assets/manifest.webmanifest`:
```json
{
  "name": "Your Business Name",
  "short_name": "Business",
  "icons": [
    { "src": "/icon-192.png", "sizes": "192x192", "type": "image/png" },
    { "src": "/icon-512.png", "sizes": "512x512", "type": "image/png" }
  ],
  "theme_color": "#0066cc",
  "background_color": "#ffffff",
  "display": "standalone"
}
```

### Step 5: Add HTML Tags

```html
<link rel="icon" type="image/svg+xml" href="/favicon.svg">
<link rel="icon" type="image/x-icon" href="/favicon.ico">
<link rel="apple-touch-icon" sizes="180x180" href="/apple-touch-icon.png">
<link rel="manifest" href="/site.webmanifest">
<meta name="theme-color" content="#0066cc">
```

Place all files in site root (`/public/` in Vite/React).

## Critical Rules

- **Always generate ALL formats** — SVG, ICO, apple-touch-icon, 192, 512, manifest
- **iOS icons MUST have solid backgrounds** — transparent = black square
- **Always use bold font weight** for monogram text (regular disappears at 16x16)
- **Test at 16x16** — if it's not legible, simplify
- **Never launch with CMS defaults** (WordPress "W", etc.)

## Format Quick Reference

| Format | Size | Transparency | Purpose |
|--------|------|-------------|---------|
| `favicon.svg` | Vector | Yes | Modern browsers |
| `favicon.ico` | 16+32 | Yes | Legacy browsers |
| `apple-touch-icon.png` | 180x180 | **No** | iOS home screen |
| `icon-192.png` | 192x192 | Yes | Android |
| `icon-512.png` | 512x512 | Yes | PWA |
