Frequently Asked Questions
What is a favicon validator?
A favicon validator is a free online tool that checks if your website's favicon meets Google Search requirements. It validates size (minimum 48×48 pixels), format (PNG/ICO preferred), and accessibility to ensure your favicon displays correctly in search results.
What size should a favicon be?
For Google Search, the favicon size must be at least 48×48 pixels, square (same width and height). If it’s smaller (e.g. 16×16 or 32×32), Google may not show it and may display a generic icon or none next to your title. Recommended sizes are 48×48, 96×96, or 192×192 pixels in PNG or ICO format. See our Favicon size guide for details.
What are Google's favicon requirements?
Google requires favicons to be at least 48×48 pixels, square (same width and height), and in PNG or ICO format. The favicon must be publicly accessible and properly declared in your HTML head section with a <link rel="icon"> tag.

What is the best format for a favicon?
For Google Search, the best format is PNG or ICO. PNG is preferred for modern sites (48×48 or larger). ICO supports legacy browsers. SVG has limited support—use PNG as primary. Read our favicon format guide for details.
Does Google Search support SVG favicons?
Google Search prefers PNG or ICO for favicons. SVG has limited support in search results. For best compatibility, use PNG at 48×48 pixels or larger, or provide PNG as primary with SVG as fallback for modern browsers.
Why is my favicon not showing in Google Search?
Common reasons include: favicon is too small (less than 48×48 pixels), not square, wrong format, not publicly accessible, or not properly declared in HTML. Google also needs time to set and update favicons—for this website it took about 6 weeks. Use our validator to identify and fix technical issues.
