Broken link checker

Check every link on a page in one go and see which ones lead nowhere.

Checked by our server

To test links, our server visits the page and each link for you. We don’t keep the page, the links or the address you check. How we handle your data

Sealed

Links on the page

We check up to 100 links on the page. Only public addresses can be checked.

Enter the address of a page to test all the links it contains.

How it works

  1. Paste the address

    Enter the address of the page whose links you want to test, such as a resources page or a long article.

  2. We test each link

    Our server reads the page, then visits each link and notes the answer: working, redirected or broken.

  3. Fix and export

    Filter the broken links, update them on your site, and export the full list to a CSV file if you need it.

Frequently asked questions

What counts as a broken link?

A link whose address answers with an error, such as 404 (page not found), 410 (gone) or 500 (server error), or a website that can’t be reached at all. Redirected links work, but it’s better to point straight to the final address.

Why does this tool need your server?

Browsers don’t let a web page test links on other websites. Our server does it for you and sends back only each link’s status. We don’t keep the page, the links or the results.

Why are some links marked “Not checked”?

For security, we never visit addresses on private or local networks, or on unusual ports. Email, phone and JavaScript links are skipped too, as they aren’t web pages.

How many links can I check?

Up to 100 links per page, which covers most pages. Links are checked in small groups, and you can stop at any time.

A link works in my browser but shows as broken here. Why?

Some websites block automated visitors, or show different content to logged-in users. If a link works for you, it may be one of those sites. You can still double-check it by opening it.
