A few months ago I decided to recreate this website’s favicon to support retina-caliber displays. I found this trickier to accomplish than I anticipated, mainly due to a dearth of good ICO-savvy icon creation tools.
Old (non-retina) favicons are 16 × 16 px; a retina favicon is thus 32 × 32 px. The lazy way to support retina is to replace your old 16 px favicon.ico file with a 32 px file, and allow non-retina browsers to scale the image. The proper solution, however, is to create a single favicon.ico file containing two icon resources: one 16 × 16, the other 32 × 32. ICO files support other resolutions as well, but I see no practical utility in doing so.
