About favicon generator / checker
A favicon is the small icon shown in browser tabs, bookmarks and search results. You can generate one from an image, or check what a site already uses.
Recommended files
- A favicon.ico containing 16, 32 and 48 px sizes.
- A 180 × 180 px apple-touch-icon for iPhones.
- 192 and 512 px PNGs for Android and web app manifests.
Design tip
Use a simple shape with strong contrast. Fine detail disappears at 16 px.
A worked example
From a 512 × 512 pixel logo the tool makes a 32 × 32 icon for tabs, a 180 × 180 pixel apple-touch-icon for iPhones and 192 and 512 pixel icons for web app manifests. Add the link tags to your page head and the files to your site root.
Checking an existing site
- Many browsers request /favicon.ico automatically if no link tag is set.
- A missing icon shows a generic globe or a 404 in your logs.
- Browsers cache favicons strongly, so a changed icon can take time to appear.
