The Favicon Checker is a developer-focused utility that audits how a website implements favicons and related assets such as Apple Touch Icons, Web App Manifests, and theme colors.

Favicons are critical for:

Brand recognition in browser tabs and bookmarks
Cross-device consistency (desktop, mobile, PWA)
Professional polish and trust
Correct display on iOS, Android, and modern browsers

This tool provides a visual preview, structured validation, and a single Favicon Score to quickly assess favicon quality and completeness.

Key Features

Paste raw HTML for local or pre-deployment testing
Detect classic (.ico) and modern (.svg, .png) favicons
Validate standard favicon sizes (16×16, 32×32, 96×96, etc.)
Detect Apple Touch Icons for iOS
Verify Web App Manifest presence
Check theme-color configuration
Preview all detected favicon assets
Generate a clear Favicon Score
Save, share, or embed results
No sign-up required

How It Works

Step 1: Enter Website URL or HTML

Step 3: Review Favicon Score

Receive a score from Poor → Excellent based on completeness and correctness.

Step 4: Inspect Detected Assets

View all favicon files, sizes, types, and preview images in a structured table.

Step 5: Apply Recommendations

Fix missing icons, incorrect sizes, or configuration issues if any are found.
