Frequently asked questions
What is a favicon ICO file?
A favicon is the small icon shown in browser tabs, bookmarks, and address bars. The .ico format bundles multiple icon sizes into one file so browsers can pick the best size automatically.
What image size should I upload?
At least 256×256 pixels gives the best downscaling quality. A square image works best since favicons are always square.
Does PNG transparency carry through to the ICO?
Yes. The tool uses PNG encoding inside the ICO container, which fully preserves alpha transparency. Your icon's background stays transparent.
How do I add a favicon to my website?
Upload favicon.ico to your site root and add <link rel="icon" href="/favicon.ico"> inside your <head> tag. Most browsers also detect it at the root automatically.
Should I use ICO or PNG for my favicon?
Use both. favicon.ico at your root covers legacy browsers; a PNG favicon declared with a <link> tag covers modern ones. This tool gives you the ICO — your source upload is the PNG.
