Dark Web
What Is the Dark Web?
The dark web is a small, deliberately hidden part of the internet. It is not a separate internet, not a single website, and not the huge criminal underworld of movie plots. It is a collection of sites that need special software to reach — and understanding it starts with separating the technology from the mythology.
Education only. This page explains what the dark web is. It does not help anyone access illegal content, buy anything illegal, or break the law. Laws differ by country — check your local law. Tor is a privacy tool, not a guarantee of anonymity.
What the dark web actually is
The dark web is a set of websites that ordinary browsers and search engines cannot reach. They use .onion addresses and run on the Tor network, a volunteer-run network that routes your connection through several relays so that no single relay knows both who you are and where you are going. To visit an onion site you need Tor Browser, the free browser published by the Tor Project.
The key word is hidden. An onion site has no public address that a normal browser can look up. Its address is derived from a cryptographic key, and the site itself lives inside the Tor network. The connection between you and the site never leaves Tor at all, which is why there is no exit relay to observe it. That design protects both sides: the visitor does not reveal their location, and the site does not reveal where its server sits.
This is what makes the dark web different from simply "a website Google has not indexed". Plenty of ordinary content is unindexed — your email inbox, your bank account, a company intranet — but it is still reachable with a normal browser and a login. Dark web sites are reachable only through Tor or a similar anonymous network, and they are built that way on purpose.
The three layers of the internet
Most confusion about the dark web comes from mixing up three layers that are genuinely different. Here they are, side by side:
| Layer | What lives there | How you reach it |
|---|---|---|
| Surface web | Public websites search engines index: news, blogs, shops, public pages | Any browser |
| Deep web | Everything search engines do not index: email, banking, paywalled articles, private accounts, internal systems | Any browser, usually with a login |
| Dark web | A small part of the deep web: sites that are deliberately hidden on Tor or similar networks | Special software such as Tor Browser |
The deep web is large, because almost everything you do online that involves an account is in it. The dark web is a small part of it. When a headline says "90 percent of the internet is the dark web", it is confusing the two — and repeating a figure that traces back to a 2001 estimate, not a measurement. Security researchers have been correcting that number for years, and honest sources now refuse to quote it as fact.
Who uses the dark web, and why
The dark web has a reputation problem, because the illegal uses are the ones that make the news. The full picture is more mixed, and it matters for understanding the technology:
- Journalists and their sources. News organisations run anonymous tip lines as onion services so sources can contact them without revealing their identity. Whistleblowing platforms used by journalists are among the best-documented lawful uses.
- People living under censorship. In countries where the internet is filtered or monitored, Tor and onion sites are a way to read blocked news and speak without being easily traced.
- Researchers and law enforcement. Security researchers study onion services to understand threats, and investigators use the same tools in their work.
- Ordinary privacy seekers. Some people simply do not want their browsing tied to their name and address, and use Tor for everyday reading.
- Criminals. Illegal marketplaces exist, and researchers and law enforcement report them regularly. They are real, they are one part of the ecosystem — and they are not the whole story.
None of this is an endorsement. It is the reason the technology exists and the reason it is legal in most countries: the same tool that hides a criminal also hides a journalist's source. The law generally judges what you do with the tool, not the tool itself.
What the dark web is not
Three common misunderstandings are worth clearing up early, because they shape every decision that follows:
- It is not a place you "go to" by accident. You cannot stumble onto the dark web by clicking a wrong link. It takes a deliberate download, a deliberate install, and a deliberate address.
- It is not invisible to everyone. Your internet provider can see that you are using Tor, even if it cannot see what you are doing. Tor hides your destination from your provider and your address from the site — it does not make your connection disappear.
- It is not a guarantee of anonymity. Logging in to an account, downloading a file, or enabling scripts can still identify you. Tor protects the connection, not your behaviour.
The risks, honestly stated
The dark web carries real risks, and they are worth stating plainly rather than sensationally. First, scams are common: marketplaces that take payment and never deliver, fake services, and extortion schemes are widely reported, and researchers have repeatedly found that advertised illegal services such as contract killings are almost always scams. There is no customer protection and no refund.
Second, malware is a genuine risk on untrusted sites, as it is anywhere on the internet — and worse where there is no reputation system to warn you. Third, the legal risk is real: merely visiting an onion site is legal in most countries, but buying illegal goods, viewing illegal material, or offering illegal services is a crime, and law enforcement does investigate dark web crime. Finally, in a small number of countries Tor itself is restricted or blocked, so using it can itself draw legal attention.
The practical conclusion is simple: curiosity about how the technology works is legitimate and legal in most places, but the dark web is not a safe shopping street, and nothing on it comes with the protections you expect from the ordinary web.
How people reach it
Conceptually, the path is short: download Tor Browser from torproject.org, install it, and open it. Tor Browser is a modified version of a mainstream browser with privacy protections built in, and it connects to the Tor network automatically. That is the whole mechanism — there is no secret handshake and no special membership.
What this site will not do is publish a directory of onion sites or a guide to finding illegal content. The technology is worth understanding; a shopping list for illegal markets is not education. The guides in this section explain how Tor works, what each relay can see, whether the dark web is illegal where you live, and how big it really is — so you can make informed decisions with real facts.

Frequently asked questions
What is the dark web in simple terms?
The dark web is a small set of websites that ordinary browsers cannot reach. They use .onion addresses and run on the Tor network, which routes connections through several volunteer relays so no single relay knows both who you are and where you are going. You need Tor Browser to visit them.
Is the dark web the same as the deep web?
No. The deep web is everything search engines do not index, including your email inbox, online banking and paywalled articles. The dark web is a small part of the deep web: sites that are deliberately hidden and need special software such as Tor Browser to reach.
Is it illegal to look at the dark web?
The technology itself is legal in most countries. Tor and onion services are legal tools in the United States, the United Kingdom, the European Union and most other countries. What matters is what you do: buying drugs, stolen data or weapons is illegal whether you do it on the dark web or anywhere else. A few countries restrict Tor, so check your local law.
Do you need Tor Browser for the dark web?
For most onion sites, yes. Ordinary browsers cannot open .onion addresses. Tor Browser is the free browser published by the Tor Project, and it is the only safe place to get it from torproject.org. Never download it from a third-party site or a search ad.
Is everyone on the dark web a criminal?
No. Journalists, researchers, activists and ordinary people who want privacy use the same tools for lawful reasons. Illegal marketplaces exist and are reported by researchers and law enforcement, but they are one part of a much smaller ecosystem than the headlines suggest.
