Frequently asked questions

What sizes should I include?

16, 32 and 48 px cover most favicon uses; add 64–256 for high-DPI displays and app icons. You choose which to bundle.

What image should I upload?

A square PNG (with transparency) gives the best result; other images are centered and scaled to fit.

Is the .ico compatible with Windows?

Yes — it uses PNG-encoded frames, supported by modern browsers and Windows Vista and later.

Is my image uploaded?

No — the icon is built entirely in your browser.
