Turn an emoji into a favicon
Pick an emoji, see it centered on a favicon at every size, and download the set. The browser paints the emoji with its own font, so what you see in the preview is what tabs will show.

How it works
Paste any emoji, pick a background or make it transparent, and ConvertICO centers it on a favicon at each size. The browser paints the emoji using its own emoji font, so the preview matches what tabs will actually show. Note that the exact look of an emoji shifts a little between operating systems, which is part of the charm. Download the favicon.ico and PNG set when you are happy.
