Tips & Best Practices

Pro Tip

You need at least 3 sizes: 32x32, 180x180, and 192x192

favicon.ico (32x32) for browser tabs, apple-touch-icon.png (180x180) for iOS home screen, and icon-192.png / icon-512.png for Android PWA manifest. Most generators produce 10+ sizes, but these three cover 95% of use cases. Use SVG favicon for modern browsers: <link rel="icon" type="image/svg+xml" href="icon.svg">.

Common Pitfall

Favicon caching is extremely aggressive

Browsers cache favicons for days or weeks, ignoring standard Cache-Control headers. After updating your favicon, users may see the old one for a long time. Bust the cache by changing the filename (favicon-v2.png) or adding a query parameter (?v=2) to the link tag. Chrome requires clearing the favicon cache at chrome://favicon/.

Real-World Example

SVG favicons support dark mode with @media queries

An SVG favicon can include <style>@media (prefers-color-scheme: dark) { ... }</style> to show a different color in dark mode. No other format supports this. The SVG can also use currentColor to inherit theme colors. Browser support is excellent: Chrome 80+, Firefox 41+, Safari 15+.

Security Note

Favicons can track users across sites

The 'supercookie' technique uses favicon cache entries as a fingerprinting vector. By serving unique favicons per user and checking which cached versions a browser requests, trackers can identify users even after cookie deletion. Modern browsers are mitigating this by partitioning favicon caches by top-level site.

Frequently Asked Questions

How do I generate a favicon from text or emoji?
Type a letter, number, or paste an emoji into the input field and the tool renders it as a favicon in multiple sizes instantly. DevBolt's Favicon Generator draws the character onto an HTML canvas, applies your chosen background color and font styling, then exports the result as downloadable PNG files in standard favicon dimensions (16x16, 32x32, 48x48, 180x180, 192x192, 512x512). You also get an ICO file for legacy browser support and the HTML link tags to paste into your page head. The entire process runs in your browser.
What favicon sizes and formats does a modern website need?
A modern website needs: a 32x32 favicon.ico for legacy browsers, a 180x180 PNG apple-touch-icon for iOS home screens, 192x192 and 512x512 PNGs in a web app manifest for Android and PWAs, and optionally an SVG favicon for crisp scaling on any display. SVG favicons support dark mode through embedded CSS media queries. Include the correct link tags in your HTML head: rel icon for the main favicon, rel apple-touch-icon for iOS, and a manifest.json entry. Placing favicon.ico at the domain root is recommended since browsers check that path automatically.
Can I use an emoji as a favicon for my website?
Yes, emoji favicons are popular for developer tools, personal sites, and documentation portals because they are instantly recognizable and require no design work. DevBolt renders the emoji onto a canvas at each required size and exports crisp PNG files. Keep in mind that emoji rendering varies slightly between platforms. Choose universally recognizable emoji and test on multiple devices. For maximum compatibility, export as PNG rather than relying on SVG text elements, since emoji font support in SVGs can be inconsistent across browsers.
