How the HTTP Referer Header Works

When you click a link on Page A to visit Page B, your browser automatically sends a Referer header to Page B revealing exactly where you came from.

You visit Page A
your-site.com/blog

✓ Referer: (empty)
No source leaked

Page B receives request

🔍 What is the HTTP Referer?

The HTTP Referer (note: misspelled in the spec) is a header your browser sends when you click a link. It tells the destination site which page or website you came from.

⚠️ Why does it matter?

Your referrer can reveal private pages, internal tools, competitor research, or sensitive URLs you were visiting. Any site can log this data.

🛡️ How to hide your referrer

Use our Dereferer tool to create links that strip the referrer header. Or add a Referrer-Policy header to your own website to control what you share.

🔬 Testing your VPN/Proxy

If you're using a VPN, your IP should change but the referrer header is unaffected by VPNs. Use Anonymiz links for referrer protection.

🛠️ How to Hide or Control Your Referrer

Use Anonymiz Links
Wrap any link in our Dereferer tool to strip the referrer header for that specific link. Works on any browser, no install needed.
Referrer-Policy Header
Add Referrer-Policy: no-referrer to your website's HTTP headers to control what you share when users leave your site.
Browser Settings
Firefox: set network.http.sendRefererHeader to 0 in about:config. Chrome: install the "Referer Control" extension.
Meta Tag Control
Add <meta name="referrer" content="no-referrer"> to your HTML to stop your pages leaking the referrer.

Frequently Asked Questions

Why does my browser send a referrer?
Browsers send the Referer header by default as defined in the HTTP specification. Websites use it to understand traffic sources and for analytics attribution. You can control or suppress it using Referrer-Policy settings.
Does a VPN stop my referrer from being sent?
No. A VPN changes your IP address and encrypts your network traffic, but it does not modify or remove HTTP headers like the Referer. To hide your referrer, use a tool like our Dereferer or set a Referrer-Policy header.
What does an empty referrer mean?
An empty referrer means the destination site cannot see where you came from. This happens when you type a URL directly, use a bookmark, come from HTTPS to HTTP, or use a Referrer-Policy of "no-referrer".
Can websites track me without the referrer?
Yes — websites can still track you using cookies, fingerprinting, UTM parameters in URLs, and IP address analysis. The referrer is just one of many tracking mechanisms. Use our Browser Fingerprint Checker to see more.
What is the Referrer-Policy header?
Referrer-Policy is an HTTP response header that controls how much referrer information is included in requests. Values include: no-referrer, strict-origin, strict-origin-when-cross-origin (default in modern browsers), and unsafe-url.
Why is it spelled "Referer" not "Referrer"?
This is a famous typo in the original HTTP specification from 1996 — the correct spelling of "referrer" was accidentally written as "referer". The misspelling has been preserved for backward compatibility ever since.
