Favicon Generator: Create a Favicon from Any Image in Seconds

A favicon is the small icon displayed in browser tabs, bookmarks, and search results. Having a custom favicon makes your site look professional and helps users identify your brand among dozens of open tabs.

What Is a Favicon?

Short for "favorite icon," a favicon is a small image (typically 16x16 or 32x32 pixels) associated with a website. Modern browsers support multiple sizes and formats including ICO, PNG, and SVG.

Favicon Formats and Sizes

  • favicon.ico - the classic format. Contains 16x16 and 32x32 versions. Still required by most browsers.
  • favicon-32x32.png - standard high-DPI favicon for modern browsers.
  • apple-touch-icon.png - 180x180 PNG for iOS home screen bookmarks.
  • favicon.svg - scalable vector favicon for browsers that support it (Chrome, Firefox). Supports dark mode with media queries.

How to Generate a Favicon

Using the SnapSum Favicon Generator, you can create all required favicon files from a single source image:

  • Upload any PNG, JPG, or SVG image (at least 512x512 recommended)
  • The tool crops and resizes it to all standard favicon dimensions
  • Download a ZIP file containing all formats and sizes
  • Add the generated HTML tags to your site's head section

Adding Favicon to Your Website

Place the favicon files in your site's root directory and add these tags to your HTML head:

  • <link rel="icon" type="image/png" sizes="32x32" href="/favicon-32x32.png">
  • <link rel="icon" type="image/png" sizes="16x16" href="/favicon-16x16.png">
  • <link rel="apple-touch-icon" sizes="180x180" href="/apple-touch-icon.png">

Favicon Design Tips

  • Keep it simple - favicons are tiny. Complex logos become unrecognizable at 16x16 pixels.
  • Use high contrast - ensure your favicon is visible in both light and dark browser themes.
  • Test at actual size - zoom out to see how it looks in a tab. If you cannot tell what it is, simplify.
  • Brand consistency - use the same color and icon as your logo or app icon.

Frequently Asked Questions

Can I use an SVG as a favicon?

Yes, modern browsers (Chrome, Firefox, Edge) support SVG favicons. SVG favicons can adapt to dark mode using CSS media queries. However, Safari support is limited, so always provide a PNG fallback.

Why is my favicon not updating?

Browsers aggressively cache favicons. Hard-refresh (Ctrl+Shift+R) or clear the browser cache. You can also add a cache-busting query string: href="/favicon.ico?v=2".
