Why isn't my favicon showing?

Favicons are often cached heavily by browsers, so changes can appear delayed.

Checklist

• Confirm you uploaded a valid favicon format and size.
• Clear cache or test in:
  • incognito/private browsing
  • a different browser/device
• Give it time: some browsers keep the old icon longer than you'd expect.

Best practice

Use a simple, high-contrast mark that stays readable at tiny sizes.
