The Best Image Search Engines on the Web

Image finders and reverse image lookup tools

An image search lets you search the web for pictures of all kinds, from portraits and clipart images to black and white photos, illustrations, line drawings, and more.

There are lots of image finders out there. Some are picture search engines that scour the web for photos and continually update their database with new images. Another way to search for pictures is from websites that host images but don't necessarily crawl the web to find new ones like a search engine does.

Below are the best image search tools that cover both types of image finders. They let you search for pictures, browse through galleries, and even run a reverse photo search to find a picture that looks like the one you have.

Some of these image finders also support uploads by its users. If not, and you want to add your own image to the web so that other people can find it, upload the picture to an image hosting website and then share the link.

Image Search Engines

Bing image search for rabbits
  • Google Images: Google's massive image database will help you find pretty much any picture on any topic that you can think of, plus it's easy to use. An advanced image search on Google lets you narrow your search by size, color, type, and more. You can also use Google to search for an image using another image as your search query instead of text, called a reverse image search.
  • Picsearch: Over 3 billion images can be found with this image search engine. Advanced options let you find black and white images, pictures of a certain color or size, wallpapers, animations, faces, and more.
  • Yahoo Image Search: The image search on Yahoo is similar to these other picture search engine sites: there are advanced image search options to filter the results by license, size, color, and more.
  • Bing Images: Another way to search images is with the Bing search engine. A trending section lets you easily find trending pictures; there's also a visual search tool (reverse photo search) and a general image lookup where you enter text to find photos, plus advanced filtering options (specific resolution, head and shoulders, transparent, color, etc).

Reverse Image Search

Google reverse image search

Ever wonder where an image you see on the web actually came from? Or maybe you made a custom photo and you're curious who else is using it. Do modified versions of an image exist elsewhere, like one in a higher resolution?

You can find all of that out with a reverse photo search. There are several ways to do this, but the idea is the same: you provide an image for your search query instead of text. For example, rather than running an image search for house, if you want to see house pictures that look like the one you have, you feed the search tool the actual picture you have instead.

A Google reverse photo search is one way to do this. Bing Visual Search and TinEye work similarly. Another way to run an image search using another image is with Pinterest; there's a visual search button on the bottom corner of photos.
