As part of my effort of removing most favicon markup from my websites, I use ImageMagick, which can create ICO format favicons from one source of image file, by converting the source image to multiple resolutions in PNG (for higher resolutions) and BMP (for resolutions 192x192 and below) formats.

That said, I noticed that mobile version of browsers may be unable to fetch a favicon that includes more than one image format, so in my ImageMagick command line, I specified the output resolution to 192x192 as the highest, so the favicon will contain only BMP format images.
