Frequently asked questions
What sizes should I include?
Use 16x16 for browser tabs, 32x32 for desktop shortcuts, 48x48 for Windows file explorer, and 256x256 for high-DPI displays. Including all sizes ensures your favicon looks crisp everywhere.
Can I use this as a favicon?
Yes. Save the .ico file as favicon.ico in your website root directory. Then add a link tag in your HTML head: <link rel="icon" href="/favicon.ico">.
Does it support transparent PNGs?
Yes. Alpha transparency from your PNG is fully preserved in the ICO file. Your favicon will display with transparent backgrounds in all supported browsers.
