Favicon Generator
One image → every favicon size your site needs.
What favicon sizes do you actually need?
Fewer than you think. Browsers and operating systems request icons on demand: favicon-32.png covers browser tabs, favicon-16.png is the legacy fallback, apple-touch-icon.png (180px) is what iOS shows when someone saves your site to their home screen, and android-chrome-192/512.png cover Progressive Web App installs. A 512px source image scales down to all of them cleanly.
Start from a square image with simple shapes — favicons are viewed at 16-32px, where detail turns to mush. If your logo is wide, put it on a solid background square first. Transparent source images stay transparent in PNG output; choose a background color only if you also want a JPEG copy.
FAQ
Do I still need favicon.ico?
Not really — all modern browsers accept PNG favicons via the link tags. Serve a .ico only for very old browsers or if your server logs show requests for it.
Why isn't my new favicon showing?
Favicons are cached aggressively. Hard-refresh, or request the file directly with a cache-busting query string (?v=2).
