PNG to Favicon Converter
Make a proper favicon.ico from a PNG — with the 16, 32 and 48px sizes browsers use — in one click, right in your browser.
What makes a good favicon
A favicon is the tiny icon in a browser tab and bookmark. Browsers look for a favicon.ico that contains at least 16×16 and 32×32; adding 48×48 covers Windows taskbar pins. Because those sizes live inside one .ico, you should not just rename a PNG — you need a real multi-size icon, which this tool builds from your PNG. Keep the artwork simple and high-contrast; fine detail disappears at 16px.
Add it to your site
Once you have the file, drop favicon.ico in your site root, or add it explicitly in your <head>:
<link rel="icon" href="/favicon.ico" sizes="any">
That is all most browsers need. Ship it, hard-refresh, and your tab icon appears.
