Generate custom favicons from logos, text, or brand colours. Produces favicon.svg, favicon.ico, apple-touch-icon.png, icon-192/512.png, and web manifest. Use whenever the user wants a favicon, mentions replacing a CMS default favicon, converting a logo into a favicon, creating branded initials icons, or troubleshooting favicon not displaying / iOS black square / missing manifest.

AI-generated overview

Generates a complete favicon package (SVG, ICO, PNG icons, manifest, HTML tags) from a logo, initials, or brand colours.

What it does
This skill walks through producing a full favicon set: it helps create a source SVG from an extracted logo icon, a monogram of initials, or a branded shape, then converts it into favicon.svg, favicon.ico, apple-touch-icon.png, icon-192.png and icon-512.png. It also supplies a web manifest template and the HTML link tags to place in the site root. Reference files cover format specifications, logo extraction, monogram patterns and shape templates.
When to use it
Use it when a user wants a favicon, needs to replace a CMS default favicon, wants to turn a logo into a favicon, needs branded initials icons, or is troubleshooting favicon display problems such as an iOS black square or a missing manifest.
Requirements
ImageMagick (the convert command) is required for the format conversions, with brew or apt install commands given as options; the skill suggests favicon.io as an alternative when ImageMagick is unavailable. It ships SVG templates and a web manifest asset plus reference documents, but no scripts. It is marked claude-code-only.

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 iconsconvert favicon.svg -resize 192x192 icon-192.pngconvert 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.)
