The favicon is the smallest piece of branding you own and the one most sites get half right. A single 16×16 file was enough in 2005. Today a browser tab wants 32×32, an iOS home screen wants 180×180, Android wants 192 and 512, and Google increasingly shows a favicon next to your result in mobile search — where a blank square makes a business look abandoned.
Feed this one square image, ideally 512×512 or larger, and it produces every size you need as clean PNGs plus the link tags to paste into your head. PNG favicons are supported by every browser in use; the old .ico format is only necessary if you still support Internet Explorer.
The design matters more than the pixel count. At 16 pixels a full logo becomes mud. Use the single strongest element — a letter, a mark, a shape — on a background with real contrast, and leave a little breathing room around it so rounded corners on mobile do not clip anything important.
Worth knowing
- Start from a square image at 512×512 or larger. Upscaling a small logo produces a blurry favicon at every size.
- Test at 16×16 before committing. If you cannot tell what it is at that size, simplify the mark.
- Upload the files to your site root and paste the generated tags into your
<head>.
Questions
Frequently asked
Do I still need an .ico file?
Only for Internet Explorer, which no longer receives support. Every current browser reads PNG favicons through the standard link tags.
Why does Google show no favicon for my site?
Common causes are a favicon that is too small, one that is not reachable from your site root, or a page blocked in robots.txt. Google also needs a crawl cycle to pick up a change.
What size should the source image be?
512×512 or larger, square, with the subject centred and a little margin around it.
