What is a search engineA plain definition with real examplesTypes of search enginesCrawler, meta, vertical, private and AIBrowser vs search engineTwo tools that people often mix upExplore
Best search enginesGoogle, Bing, DuckDuckGo and moreUses of search enginesThe everyday jobs that search handlesHistory of search enginesFrom Archie in 1990 to AI answersThe difference between browser and search engine tools comes down to their jobs. A browser is the app that opens web pages on your device, while a search engine is a website that helps you find those pages. This guide explains how each one works, with a side-by-side table, an everyday analogy and real examples.
A web browser, such as Chrome or Safari, is software that loads and displays websites. A search engine, such as Google or Bing, is a service you open inside a browser to look for websites by typing words.
The short answer
People mix the two up because they usually appear together on the same screen. Once you see what each one does on its own, the line between them becomes easy to spot.
A browser is a program installed on your phone, tablet or computer. It requests pages from websites, then turns their code into the text, images and buttons you see on screen.
A search engine is a service that has already scanned a huge share of the web. When you type a question, it returns a list of pages that seem to match what you asked.
Put simply, you need a browser to visit any website at all, including a search engine. You only need a search engine when you do not already know the address of the page you want. If you are new to the idea, our guide on what a search engine is covers the basics in more depth.
Side by side
The quickest way to compare the two is to line up what each one is, where it lives and what it does for you.
| Feature | Web browser | Search engine |
|---|---|---|
| What it is | An app installed on your device | A website or service on the internet |
| Main job | Opens and displays web pages | Finds pages that match your words |
| Do you install it? | Yes, or it comes with your device | No, you visit it through a browser |
| Needs the other? | Works without a search engine if you know the address | Needs a browser or app to be used |
| Stores | Your bookmarks, history, passwords and open tabs | A huge index of pages from across the web |
| Examples | Chrome, Safari, Firefox, Edge | Google, Bing, DuckDuckGo, Yahoo |
| Can you switch? | Install a different browser app | Pick a new default in browser settings |
Read across the rows and the browser vs search engine question turns out to describe two partners. One is the vehicle, while the other is a service you reach with it.
Everyday analogy
If the technical wording still feels abstract, comparing the web to a road trip usually helps.
A browser works much like a car on a road trip. It gets you to any address you type in, whether that is a news site, your bank or a shop. Without it, you are not going anywhere on the web.
A search engine is like a sat nav that answers a request such as nearby coffee shops. It lists options, yet you still need the car to drive there.
A second picture works for people who prefer libraries. The browser is the reading room where you sit to open books, while the search engine is the catalogue that shows which shelf holds your book.
In both pictures, you can skip the guide whenever you already know the destination. Typing a full web address goes straight to the site with no search engine involved.
Real examples
Below are the names most people meet every day. Browsers appear in the first table, followed by the search engines you might open inside them.
| Browser | Made by | Usual default search engine |
|---|---|---|
| Google Chrome | ||
| Safari | Apple | Google in most regions |
| Mozilla Firefox | Mozilla | Google in most regions |
| Microsoft Edge | Microsoft | Bing |
| Brave | Brave Software | Brave Search in many regions |
| Samsung Internet | Samsung | Google in most regions |
The most widely used search engine, which also offers image, news, map and shopping results.
Search engineMicrosoft’s search engine. It is the default in Edge, while its results also feed several other services.
Search engineA privacy-focused search engine that does not build a profile of you. It also offers its own browser app.
Search engineYou will notice that several companies appear in both lists. That overlap explains most of the confusion, because the same brand can make a browser alongside a search engine.
The big confusion
This is the question people ask most often, which makes sense once you see how many products carry the Google name.
Google is a company, so the word on its own does not describe a single tool. Google Search, the page with the famous search box, is a search engine. Google Chrome is a browser, released in 2008, that you install on your computer or phone. Both are made by the same company, yet they do different jobs.
The confusion grows because Chrome opens Google Search by default. When you type words into the Chrome address bar, the results come from Google, so it can feel as if the browser itself did the searching. In fact, Chrome simply passed your words to the search engine, then showed you the page it returned.
The same pattern repeats with other big technology companies. Microsoft makes the Edge browser along with the Bing search engine, while Brave Software makes the Brave browser together with Brave Search.
How they work together
Modern browsers merge the address bar with a search box, so a single line at the top of the screen handles both jobs. Here is what happens behind the scenes.
Each step happens in well under a second, which is why the two tools feel like one. The search engine does its own heavy work long before you type, as our guide on how search engines work explains step by step.
Type anything into the pretend address bar, or tap an example, to see whether the browser opens a website or passes your words to a search engine.
It looks like a web address, so the browser goes straight to that site.
It looks like a question or plain words, so the browser asks your default search engine.
Take control
Because the browser and the search engine are separate, you can keep your favourite browser while switching the engine it uses. The exact menu names vary between versions, although the route is similar everywhere.
On an iPhone or iPad, Safari’s search engine is chosen from the Safari section of the Settings app. If an engine you want is missing from the list, visiting its homepage often adds it as an option. Our overview of the types of search engines can help you decide which style suits you.
Why it matters
Understanding which tool does what is more than trivia. It helps you fix problems faster, protect your privacy and make better choices.
If pages will not load at all, the problem usually sits with the browser or your connection. If results feel poor, switching search engines is the more likely fix.
Your browser keeps a history on your device, while a search engine may store your searches on its servers. Clearing one does not clear the other.
Browser updates patch security holes on your device. Search engines update on their own servers, so you never need to install them.
You can pair almost any browser with almost any search engine. That freedom only makes sense once you see them as two separate tools.
These everyday habits sit at the heart of our search engine basics guide, which explains the wider topic in the same plain style.
FAQ
No. Chrome is a web browser made by Google. It uses Google Search by default, although you can switch it to another search engine in its settings.
Usually you need some kind of browser or app to reach a search engine. Phone apps from Google, Bing or DuckDuckGo include their own built-in page viewer, which works like a small browser.
Safari is the web browser Apple builds into its devices. It sends address bar searches to a search engine, which is Google by default in most regions.
Simple search tools such as Archie, created in 1990, appeared before the first graphical web browsers became popular. Both grew together once the web took off in the mid-1990s.
No. Bing is Microsoft’s search engine, while Edge is Microsoft’s browser. Edge uses Bing by default, which is why the two are often confused.
