Make a Google-ready favicon from a square logo
Start with a simple square logo that remains recognizable at very small sizes. Fine text, thin lines, and detailed photographs usually disappear when reduced to a browser-tab icon.
The generator redraws the source locally into common PNG sizes and an ICO package. Inspect the 16, 32, and 48 pixel results rather than judging only the large preview.
Publish the files at stable crawlable URLs and reference the preferred favicon in the site head. Do not block the icon or its page in robots.txt. Use one consistent identity rather than changing icons for individual pages.
Google Search generally expects a square favicon whose dimensions are a multiple of 48 pixels. Meeting the technical requirement does not guarantee immediate display; crawling and search presentation can take time.
After deployment, test the icon in a browser, validate the URLs directly, and request recrawling through Search Console when appropriate. Avoid changing the path on every build.
