Use Base64 wisely
Base64 is ideal for text-only APIs, small embedded assets, test fixtures, and portable documents. It increases payload size, so external files are usually better for large public assets.
Frequently asked questions
Which image formats work best for favicons?
PNG and SVG are the most common. ICO files also work when the browser can read them.
Where do I paste the generated link tag?
Place the link rel="icon" element inside the head section of your HTML document.
When should I use Base64 for embedded favicons?
Use it when a text-only channel or API must carry binary data, or when a small embedded favicons asset needs to live inside a self-contained document. Prefer separate files for large, cacheable public assets.
