Only the public web page and its icon files are read – nothing is stored.
Type a website address into the Img Stop Favicon Checker and click Check favicon. It opens the page, finds every icon link, downloads each file and checks the SVG, 96×96 PNG and ICO favicons, the Apple touch icon and the web app manifest. Green means OK, yellow is a warning and red is an error, with a preview of how the icon looks in a browser tab, Google, iPhone and Android.
About the Favicon Checker
The Img Stop Favicon Checker tests the icons of any public website in a few seconds. It reads the home page HTML, lists the favicon, apple-touch-icon and manifest links it finds, downloads every file and checks that it exists, has the right type, is square and has the size browsers and search engines expect.
You see a clear list of what is right in green, what could be better in yellow and what is broken in red – for example a missing 48 px size in favicon.ico, a touch icon with a transparent background that turns black on iPhones, or a manifest without a 512 px icon. If something needs fixing, the Website Favicon Generator makes a complete, correct set in one click.

Tips for the best result
- Check the home page – search engines take the favicon from there.
- If you just uploaded new icons, clear your site and CDN cache first; results are cached by the checker for 10 minutes.

- Sites behind strict firewalls may block the checker – test the icon files in your browser in that case.
Frequently asked questions
How do I check if my favicon works?
Enter your website address in the Img Stop Favicon Checker. It downloads every icon your page declares and shows green, yellow or red for each check, plus a preview of how the icon looks in a tab, in Google and on phones.
Why is my favicon not showing?
The most common reasons are a wrong file path in the link tag, a missing favicon.ico in the main folder, an old cached icon in the browser or CDN, or a file blocked by robots.txt or a firewall. The checker shows which file is missing or broken.
Why doesn't Google or Bing show my favicon?
Search engines need a square favicon that is a multiple of 48 px (such as 48×48 or 96×96), linked from the home page and crawlable. New icons can take days or weeks to appear after the next crawl.
What do the yellow warnings mean?
Warnings are not fatal, but fixing them improves how your icon looks – for example adding an SVG favicon, a 96×96 PNG or a web app title for iPhones.
Does the checker store the website or icons?
No. The page and icon files are read once to run the checks and are not saved. The result is kept in a short cache for 10 minutes so repeated checks are fast.
Can it check a site on localhost or an intranet?
No, only public websites on the internet can be checked.
