Question 1

What image format should I use for the best favicon?

Accepted Answer

A square PNG or SVG works best. Ideally use a 512×512 or larger image so the generator can downscale cleanly to all required sizes.

Question 2

What favicon sizes do I need for my website?

Accepted Answer

At minimum: 16×16 and 32×32 for browser tabs, 180×180 for Apple Touch Icon, and 192×192 for Android. For PWAs also add 512×512.

Question 3

Can I generate a .ico file?

Accepted Answer

This tool generates PNG files at all required sizes. Modern browsers support PNG favicons. For a .ico file, use the 16×16 or 32×32 PNG — most hosting platforms accept PNG for favicons.
