FAQ
How do I create an .ico favicon for my site?
Upload your logo as PNG or JPG, and the tool converts it into a multi-size .ico file. Then place favicon.ico at your site's root or declare it with a <link rel="icon"> tag.
What image size should I use for a favicon?
Ideally start from a square image of at least 256x256 pixels. The .ico format can contain several resolutions (16x16, 32x32, 48x48) that browsers and Windows pick depending on context.
Does the .ico format support transparency?
Yes, the .ico format supports alpha transparency when generated from a transparent PNG. Your favicon will therefore display correctly whatever the tab's background color.
