How to Block Images From Google With Robots.txt

To keep images out of Google Images, add a rule for the Googlebot-Image user agent that disallows the folder or file. This stops that crawler fetching those images, but it does not hide them from people who have the direct link and it does not instantly remove images that are already indexed.

The rule

User-agent: Googlebot-Image
Disallow: /private-images/

This blocks the Google Images crawler from that folder only. To block every image on the site, use Disallow: / under the same user agent, though that is rarely what a business wants.

Block one file type

User-agent: Googlebot-Image
Disallow: /*.gif$

The pattern uses the wildcard rules explained in robots.txt wildcards.

What this does not do

It does not password-protect the files.
It does not stop other crawlers unless you add rules for them.
It does not remove images already in the index quickly. Use the removals tool or return an error status for urgent cases.

Be careful about blocking useful images

Images help pages rank for image search and help Google understand content. Blocking product or portfolio photos by accident can reduce visibility. If you want images found, follow image SEO best practices instead.

Test the rule

Write the rule with the robots.txt generator, then check a sample image URL in the robots.txt tester.

Frequently asked questions

Will blocking images hurt my page rankings?

It can reduce image search traffic and give Google less context about the page, so block only what you truly need to.

Can I allow one image inside a blocked folder?

Yes. Add a more specific Allow rule for that file.
