❓ Frequently asked questions
What is a favicon?
A favicon is the small icon shown in browser tabs, bookmarks and address bars. It helps visitors recognize your website at a glance and gives your site a professional, finished look.
ICO vs PNG — which favicon format should I use?
Use both: favicon.ico for maximum compatibility with older browsers, plus a PNG favicon for modern browsers that render it sharper. This tool generates both formats from one image.
What sizes should my favicon include?
Include 16×16 and 32×32 for browser tabs, 48×48 for shortcuts, and a 180×180 apple-touch-icon so your site looks right when saved to a phone home screen.
How do I add a favicon to my website?
Upload favicon.ico to your website's root folder and add the link tag <link rel="icon" href="/favicon.ico"> inside your page's head section. Most browsers also pick up a root-level favicon.ico automatically.
Why does my favicon look blurry?
Blur usually comes from starting with a tiny or non-square image. Upload a large square source (512×512 or bigger) with simple, high-contrast shapes so it stays crisp at 16×16.
Can I use an emoji or photo as a favicon?
Yes — emojis and photos work fine as long as the image is cropped to a square first. Simple bold shapes read best at tiny sizes; fine detail disappears at 16×16.
