Favicon Checker

Pixellize’s Favicon Checker verifies if your website has a properly configured favicon.

What is a Favicon Checker?

A favicon checker is a free online tool that scans your website to see if your favicon is correctly implemented. A favicon is the tiny icon that appears in your browser tab, bookmarks, and even search results. While small, it’s a powerful element for branding and trust.

When users bookmark your site or switch between multiple tabs, your favicon helps them quickly recognize your brand. Without a favicon, your website can appear incomplete or less professional.

How to Add a Favicon to Your Website

To display a favicon, you need to add a <link> tag inside the <head> section of your HTML:

<link rel="icon" href="/path/to/favicon.ico">

Common rel values include:

  • icon
  • shortcut icon
  • apple-touch-icon
  • apple-touch-icon-precomposed

Once added, most browsers will automatically detect and display your favicon.

Best Practices for Favicons

  • Brand Recognition – Choose a favicon that clearly represents your brand.
  • Right Dimensions – Use square multiples like 48×48, 96×96, or 144×144 pixels. SVG files are fully scalable.
  • Keep it Simple – Small details get lost; clean and bold designs work best.
  • Correct File Format – .ico, .png, and .svg are the most common favicon formats.
  • Verify Implementation – Always test your favicon with our Favicon Checker to make sure it’s not blocked and loads properly.
