How to get 2x badge in Chrome extension

Question

It seems chrome://favicon/to allow me to get the 16x16 icon and it looks blurry on the retina screens. What if I want to get a 2-mesh grid icon?

Answer 1

These URLs should work:

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

Notes:

• In some versions of Chrome, you can always return the 16x16 icon (or a version with a sub-extension).
• Many (most?) Sites provide only the 16x16 icon, and there is nothing you can do about it.
• The favicon key receives an icon only when the corresponding web page is fully loaded.
