FAQ
What is a favicon and why do I need one?
A favicon is the small icon displayed in browser tabs, bookmarks, and address bars next to your website name. It helps users quickly identify your site among multiple tabs and creates a professional appearance. Most browsers automatically look for favicon.ico in your website root directory.
What sizes should I include in my favicon?
The most important sizes are 16×16 and 32×32 which are used in browser tabs and bookmarks. Including 48×48 provides better quality on high-DPI displays. Larger sizes like 128×128 and 256×256 are useful for Windows desktop shortcuts and taskbar pinning.
Should I use ICO or PNG format for favicons?
The ICO format has the advantage of containing multiple sizes in one file, making it work automatically across all scenarios. Modern browsers also support PNG favicons specified with link tags, which can provide better compression for complex images. Using both is the best approach for maximum compatibility.
Why does my favicon look blurry at small sizes?
Small icons like 16×16 have very limited pixels to work with. Fine details and thin lines may not render well. Consider simplifying your design for small sizes or manually editing the 16×16 version to optimize important elements. The preview feature helps you check quality before generating.
How do I add the favicon to my website?
Place the favicon.ico file in your website root directory. Most browsers automatically detect it there. You can also explicitly reference it by adding this tag to your HTML head section: <link rel="icon" href="/favicon.ico">. Clear your browser cache to see changes immediately.
