Favicon Best Practices for Modern Web Apps
A favicon (short for favorite icon) is a small, iconic image that represents your website. Despite its tiny size, it plays a massive role in branding, tab organization, and even Google Search results.
The Evolution of Favicons
We've moved past the days of a single 16x16 .ico file. Today, web apps must cater to Retina displays, Android home screens, iOS touch icons, and Windows tile graphics.
Essential Formats for 2026
- SVG: The modern standard. A single vector graphic scales perfectly to any size and supports dark/light mode switching via CSS media queries inside the SVG file.
- PNG (32x32): The fallback for older desktop browsers that don't yet support SVG favicons.
- Apple Touch Icon (180x180 PNG): Required if you want a high-quality icon when iOS users "Add to Home Screen".
- Android Chrome (192x192 & 512x512 PNG): Defined in your
manifest.jsonfor Android PWA installations.
Favicons and Google Search SEO
Google now prominently displays favicons next to search results on mobile and desktop. A clear, high-contrast icon increases your Click-Through Rate (CTR). If your site lacks a favicon, Google displays a generic globe icon, which looks unprofessional and harms trust.
