What is the best favicon size for my website?

For modern websites, we recommend a 32x32 ICO file containing both 16x16 and 32x32 sizes, plus a 180x180 Apple Touch Icon for iOS, and 192x192/512x512 icons for Android Chrome/PWA. SVG favicons are increasingly supported but should be paired with PNG fallbacks. This tool helps you preview how your icon looks at all these sizes.

How do I make my favicon work in dark mode?

Modern browsers (Chrome 96+, Firefox 103+, Safari 15.4+) support SVG favicons with CSS media queries for prefers-color-scheme. You can also use the media attribute on link tags to serve different icons for light and dark mode. This tool lets you preview your favicon on both light (#ffffff) and dark (#0f172a) backgrounds to ensure good contrast across all themes.

What file formats are supported?

This tool supports PNG (recommended), ICO (multi-size icon format), SVG (vector format), and JPEG images. All processing happens locally in your browser — your icons are never uploaded to any server. Animated GIF favicons are not supported for preview. For best results across all browsers, provide at minimum a 32x32 PNG favicon.

Why does my favicon look blurry in the browser tab?

Browser tabs display favicons at 16x16 pixels, which is very small. If your icon has fine details, thin lines, or complex gradients, it will appear blurry at this size. To fix this: use simple geometric shapes with thick outlines; test readability at 16x16; avoid excessive detail or gradients. Our tab preview simulation helps you see exactly how your icon performs at small sizes.

What is a favicon and why is it important?

A favicon (short for "favorites icon") is the small icon displayed in browser tabs, bookmarks, and history. It's a key brand identifier that helps users quickly locate your website among many open tabs. A well-designed favicon improves brand recognition and makes your site look more professional. This tool helps you test how your favicon performs at actual display sizes.

What icon sizes do I need for my website?

A complete favicon setup includes: favicon.ico (16x16 + 32x32 multi-size), Apple Touch Icon (180x180 for iOS home screen), Android Chrome icons (192x192 and 512x512 for PWA). Use HTML link tags with rel="icon" and rel="apple-touch-icon" to specify different sizes. This tool previews all these common sizes so you can verify quality at each resolution.
