The favicon files a site needs in 2026
You do not need twenty icon sizes. A modern set is small:
- favicon.ico (16, 32 and 48 px inside one file): the fallback every browser and crawler asks for at /favicon.ico. Google Search shows your favicon next to results and needs it to be at least 48 px.
- favicon-32x32.png and favicon-16x16.png: crisp tab icons.
- apple-touch-icon.png (180 px): used when someone adds your site to an iPhone home screen. iOS adds its own rounded corners, so square art is fine.
- android-chrome-192x192.png and 512x512.png: listed in site.webmanifest for Android home screens and install prompts.
The generator makes all six PNGs and packs the three small ones into a real multi-size .ico file, built in your browser.
Designing for 16 pixels
At tab size you have about 16 × 16 dots. Wordmarks and detailed logos turn to mush. What works:
- One letter or one emoji. Two letters can work in bold; three is pushing it.
- Bold weight so strokes survive the downscale.
- Strong contrast between text and background. Check it in a dark-mode browser tab too.
- A filled shape. A solid background stands out in a row of tabs better than transparent art.
Installing it
Put the files in your site's root folder, then paste the link tags into the <head> of every page and save the manifest as /site.webmanifest. Browsers cache favicons hard; if you do not see the change, open the icon URL directly or try a private window.
Pair it with a matching share image from the OG image generator and check the result with the Open Graph checker.
