Welcome to the Anonymizer Anonymous Web Surfing Service. With this service you will be able to surf the web in total privacy. To use your Anonymizer account any time, from any computer, just go to, log in, and start surfing anonymously.

When you're surfing the web, what you do can be seen by:

Often the data about where you surf goes into a personal profile that can include your real name, address, and credit card number. This information is then sold between companies, or worse, puts you at risk of identity theft and credit card fraud.

What our Anonymous Surfing Service does:
We make you invisible while you surf. No one but you will ever know what sites you're visiting, what you search for, or what you download. There's no software to install, you just come to our site and log in as a member, then start surfing anonymously. It costs less than $5 per month to subscribe; and there's a freee trial version to test also.

Our mission is to ensure that an individual's right to privacy is not compromised by going online. was founded to provide the means to protect this right as embodied in the United Nations' Universal Declaration of Human Rights:

No one shall be subjected to arbitrary interference with his privacy, family, home or correspondence, nor to attacks upon his honour and reputation. Everyone has the right to the protection of the law against such interference or attacks.

The Internet has made article 19 of this 50-year-old document more applicable than ever:
Everyone has the right to freedom of opinion and expression; this right includes freedom to hold opinions without interference and to seek, receive and impart information and ideas through any media and regardless of frontiers.

URL Encryption encrypts web site addresses (URLs) so that only the Anonymizer can read them. When you use Anonymizer Surfing normally (without URL Encryption), web site addresses look something like this:

However, surfing with URL Encryption renders the URL of the sites you are visiting unintelligible:

Why is this useful?

Requests to load a page anonymously are sent by your web browser to our Anonymizer servers. Unless you are using our SSH Tunneling service, these requests travel over the Internet "in the clear" (as plain text). Thus, it is possible for your ISP, network administrator, or other intermediary to easily log the sites that you visit. URL Encryption™ prevents this invasion of privacy by rendering the URLs of the web sites you visit meaningless to outside observers.

Who can use URL Encryption™?

All of our Anonymous Surfing subscribers.

How do I use URL Encryption™?

To enable it when you log in, click the "URL Encryption on" button on the Members Login Page. You can toggle URL Encryption on and off at any time while you are surfing via the "Control Panel" button on the Anonymizer bar included at the top of each page you visit. URL Encryption is toggled on the Control Panel by the "URL Encryption on/off" radio button.

Why does URL Encryption™ require cookies?

Because there is no other way for the Anonymizer to keep track of who has URL Encryption turned on or off. Our users are anonymous, after all! If you examine the cookie set for URL Encryption, you will see that it contains no identifying information about you whatsoever. It carries only the value URL_Encryption=On or URL_Encryption=Off. For more information about cookies, Cookie Central is an excellent resource. Remember that the Anonymizer still stops all cookies by default; unless you're using Safe Cookies™, we never let cookies from the sites you visit through.

Can I use bookmarks with URL Encryption™?


What is to prevent an intermediary (or other adversary) from getting an Anonymizer account so as to be able to decrypt my Encrypted URLs?

The algorithm used for URL Encryption encrypts URLs differently for each one of our users. Thus, there is no way for anyone else to decrypt your URLs short of stealing your password and logging into your account.

Why are Encrypted URLs longer than their plaintext counterparts?

The short answer is: so that the same URL never encrypts the same way in two browsing sessions. If you're familiar with cryptography, the technical answer is: we encrypt in CBC mode; the "extra" length you see is the Initialization Vector.

How secure is URL Encryption?

URL encryption uses 128-bit Blowfish, an algorithm and keylength considered to be strong enough that it would be foolish for anyone to attempt to break it by brute force. It would be far easier for someone to "bug" your computer or try to infer the URL from the content of the pages you request than to break the encryption. (Using Secure Tunneling prevents such snooping). The bottom line: URL Encryption protects against the common forms of logging and request snooping employed by ISPs and other intermediaries.

Who subscribes to the Anonymizer?

A: We receive subscriptions from people in all walks off life. Many individuals use the Anonymizer for general surfing and web research so that their interests are not tracked. For example, an Anonymizer user investigating a health problem has no fear that the activity will be recorded and made available to his or her insurance company. Others use the Anonymizer to visit sites heavy with profit motive or conflicting intent, such as the web site of a competitor. As webmasters become more savvy and web users become more concerned, we find that the diversity of our users is increasing. Because we require very little information from our subscribers and do not track their browsing habits, this information comes from conversations, email, surveys, and other market research
