Favicon and App Icon Setup

Generate the site's favicon assets and wire them into the public head tags. This skill is for the small but visible icon set every marketing site needs in browser tabs, bookmarks, mobile home screens, and search previews.

What this skill produces

• public/favicon.svg
• public/favicon.png
• public/favicon.ico
• public/apple-touch-icon.png

If the site already has some of these files, patch only the missing or outdated ones.

Steps

1. Find the brand mark

Look for the strongest existing source of the site's identity:

1. src/assets/, public/, or any design export assets for a logo, glyph, or wordmark
2. index.html or the homepage copy for a clean initial monogram if no logo exists
3. The brand colors from the design system or the page styles

Prefer a simple, high-contrast mark that still reads at 16x16. If there is no logo, create a minimal monogram or symbol rather than trying to fit the full wordmark into the favicon.

2. Create public/favicon.svg

Use SVG as the source of truth whenever possible. Keep it simple, square, and legible at small sizes:

• single background shape or transparent background
• one primary glyph or monogram
• no tiny text
• no thin strokes that collapse at 16px

If the site already has a vector logo, simplify it for favicon use instead of copying the full mark unchanged.

3. Generate raster fallbacks

Create the raster variants from the SVG:

• public/favicon.png at 512x512 or 256x256
• public/apple-touch-icon.png at 180x180
• public/favicon.ico with multi-size support for legacy browsers

Use the existing asset pipeline if the repo already has one. Otherwise generate the PNGs from the SVG and build the ICO from the PNG.

4. Keep the head tags aligned

Make sure the site references the new icon files in index.html or the shared meta-tags component:

<link rel="icon" type="image/png" href="/favicon.png" />
<link rel="icon" type="image/svg+xml" href="/favicon.svg" />
<link rel="shortcut icon" href="/favicon.ico" />
<link rel="apple-touch-icon" href="/apple-touch-icon.png" />

If /senternet-site-metatags has already been run, update only the missing references or replace stale placeholder paths.

5. Verify the result

Check the generated files at browser-tab size and on a dark and light background:

• the icon should still be recognizable at 16x16
• the SVG should not depend on external fonts or scripts
• the PNG should not be blurry
• the ICO should exist for compatibility

If the favicon is used in a prerendered or deployed site, confirm the public paths resolve from the final hosting root.

6. Commit the generated assets

These files are generated build outputs, so commit them as the final step, never leaving the working tree dirty across sessions. Stage the generated icons together with any head-tag wiring from Step 4 and commit with a descriptive message:

git add public/favicon.svg public/favicon.png public/favicon.ico public/apple-touch-icon.png
git add index.html   # and/or the shared meta-tags component, if the icon references changed
git commit -m "Add favicon and app icon assets"

If you only patched a subset of the icons, stage just those files. Confirm git status is clean before finishing.

Notes

• Keep favicon design intentionally simpler than the main logo
• Favor one bold shape over detail
• Reuse the brand accent color only if contrast stays strong
• Do not use oversized transparent padding around the mark
