Favicon Checker: Preview Any Site Icon at Every Size
See a domain's icon at 16, 32, 48, 180 and 512px, and get the correct link tags.
Runs entirely in your browser. Nothing is uploaded, no account needed.
What this does
Favicons fail quietly. The tab shows the default globe, the bookmark bar shows a blank square, the iOS home screen shows a screenshot of your page, and nobody notices for a year. Enter a domain and see the icon files it actually serves, at the sizes each surface actually renders.
How to use it
Enter a domain
Any hostname works. The tool requests the conventional icon paths directly as images, which a browser is allowed to do cross-origin, and reports which ones came back.
Check every surface
The same icon is drawn at 16px (browser tab), 32px (bookmark bar and retina tab), 48px (Windows shortcut), 180px (iOS home screen) and 512px (PWA splash and Android), on both a light and a dark chrome.
Copy the link set
A modern, minimal set: an SVG icon, a 96px PNG fallback, the .ico for legacy, apple-touch-icon, and the manifest reference. Five lines, not the twenty-eight a generator from 2015 gives you.
Frequently asked questions
What favicon sizes do I actually need in 2026?
Four files. favicon.ico (containing 32x32) for legacy and for the many crawlers that only look there, icon.svg for everything modern and for dark-mode variants, a 180x180 apple-touch-icon.png for iOS, and a 512x512 PNG in your web app manifest for Android and PWA installs. Everything beyond that is history.
Why does the tool show a blank for some sizes?
It only reports files that exist at the conventional paths. A site that declares a custom path in its HTML (which a browser on another origin cannot read) will show blanks here while working fine in a tab. That is a limitation of doing this without a server, and it is called out on the result.
Can a favicon change with dark mode?
Yes, if it is an SVG. An inline <style> with a prefers-color-scheme media query inside the SVG is honored by Chrome and Safari when the file is referenced with rel="icon" type="image/svg+xml". ICO and PNG cannot do this.
Why is my favicon cached forever?
Because browsers cache icons far more aggressively than pages, and Chrome keeps them in a separate database that a normal hard refresh does not clear. Ship a new filename (icon-v2.svg) rather than trying to bust the cache on the old one.
