How to get 2x favicon in Chrome extension

Question

It seems chrome://favicon/ only allows me to get a 16x16 favicon, and it looks blurry in Retina screens. What if I want to get a 2x retina ready favicon?

Answer 1

These urls should work:

• 16px for retina: chrome://favicon/size/16@2x/http://www.apple.com/
• 48px: chrome://favicon/size/48/http://www.apple.com/

Notes:

• Some versions of Chrome may always return a 16x16 icon (or a subpar stretched version).
• Many (most?) sites provide only a 16x16 icon and there's nothing you can do about it.
• The favicon cache gets an icon only when the corresponding web page is completely loaded.
