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