Favicon & Touch Icon Checker Guide

What are Favicons and Touch Icons?

Favicons (favorite icons) are small 16x16 or 32x32 pixel images that appear in browser tabs, bookmarks, and address bars. Touch icons are larger versions used on mobile devices when users add your website to their home screen.

These icons might seem minor, but they're crucial for:

• Brand recognition across browsers and devices
• Professional appearance that builds trust
• User experience on mobile platforms
• SEO signals that search engines consider

Types of Website Icons

1. Classic Favicon (favicon.ico)

The traditional favicon file placed in your website's root directory.

<!-- Automatically detected at /favicon.ico -->

Specifications:

• File format: ICO (can contain multiple sizes)
• Common sizes: 16x16, 32x32, 48x48 pixels
• Location: Website root (https://yoursite.com/favicon.ico)

2. Modern PNG Favicons

Newer browsers support PNG favicons with better quality and transparency.
