Frequently asked questions
Why include several sizes in one ICO?
Browsers and Windows pick the size that fits: 16 px for browser tabs, 32 px for taskbars and shortcuts, 48 px and up for larger icon views. One multi-size file looks sharp everywhere.
What if my PNG is not square?
It is scaled to fit inside each square size with transparent padding, so nothing is cropped. A square source gives the best result.
Is the result a real .ico file?
Yes. The tool writes a genuine multi-image ICO container, not a renamed PNG, so Windows and older browsers read it correctly.
Do I still need other favicon files?
Modern sites often add a 180 px Apple touch icon and PNG icons as well. The favicon generator on this site creates the full set.
Is my logo uploaded?
No. The icon is built in your browser.
