FAQ

What favicon sizes do I need?

Common: 16x16 (tab), 32x32 (taskbar), 48x48 (Windows), 180x180 (Apple Touch).

What format for favicons?

PNG is widely supported. ICO can contain multiple sizes.

Can I use emoji?

Yes! Modern browsers support emoji favicons with custom backgrounds.

What is the minimal valid ICO file format?

A minimal valid ICO file contains a 6-byte header (magic bytes, type, image count), a 16-byte directory entry (size, color info, data offset), and the image data. The smallest practical favicon is a 16x16 pixel ICO file, typically a few hundred bytes.

Should I use ICO, PNG, or SVG for my favicon?

ICO is the traditional format that supports multiple sizes in one file. PNG is widely supported and simpler. SVG favicons are the newest option, supported in modern browsers, and scale perfectly to any size. Use ICO for maximum compatibility.

How do I add a favicon to my website using Base64?

Add this to your HTML <head>: <link rel="icon" href="data:image/png;base64,...">. This embeds the favicon directly in your HTML without needing a separate file. This tool generates the Base64 data URI ready to use.

What favicon sizes should I include for PWA manifest?

For Progressive Web Apps, include 192x192 and 512x512 PNG icons in your manifest.json. Also include 16x16, 32x32, and 180x180 (Apple Touch) for complete browser and device coverage.

Why isn't my favicon showing up?

Common issues: browser cache (try hard refresh with Ctrl+Shift+R), wrong file path in the <link> tag, incorrect MIME type, or the ICO file is malformed. Place favicon.ico in your site root as a fallback, since browsers check there by default.
