title: Can one large size favicon serve all devices and browsers?
body: <p>All discussion about favicons recommend creating favicons of different sizes to target different clients. See this answer for example: <a href="https://stackoverflow.com/a/19590415/1235698">Does a favicon have to be 32x32 or 16x16?</a></p>
  
  <p>My question: Is it really necessary to generate favicons with so many different size? What if I created one large favicon of size 200x200? I see various browsers like Chrome and Firefox automatically scaling it down to display a pretty scaled-down favicon in the browser tab.</p>
  
  <p>What's the problem in going for one large favicon of size 200x200 then?</p>
  
  <p>Note: I want the favicon to work on any device browser that conforms to the standard (if there is one for favicon). For example, if iOS Safari violates the standard then I am not too bothered with supporting it.</p>
