Safari 9 on OSX supports showing icons on its new pinned tabs, using the following syntax:

<link rel="mask-icon" color="red" href="/mask-icon.svg">

However after adding this line, reloading my page, and pinning the tab, the icon doesn't show up.

How do I tell it to refresh the icon?

This question came from our site for pro webmasters.


Safari is very keen to cache these icons, and indeed the lack of them. Once it has decided there is (or is not) an icon on your site, it will retain that knowledge, potentially for a very long time, and no amount of restarting or refreshing will change that.

You can encourage it to re-check for icons by deleting the contents of the following folder:

~/Library/Safari/Template Icons

And then restarting Safari.

  • This directory won't be created until a pinned site has downloaded a pinned icon. Try Apple's website to kickstart it. – mix3d Mar 21 '17 at 1:46

Unpin any pins you want to reload then restart safari. Click on the 'go' menu in the finder toolbar and hold down the option key, this reveals the hidden Library directory.

Navigate to the safari directory in the library folder and delete the template icons folder.

This resets the cache safari keeps for icons.

Start Safari and pin away!


Open Safari, click "Safari", "Clear History...", then click the button "Clear History".


That worked for me.

  1. Open Safari > Develop > Empty Caches.
  2. Refresh the page

Note: If you don’t see the Develop menu in the menu bar, choose Safari > Preferences, click Advanced, then select “Show Develop menu in menu bar.”

That did the trick for me ;)
