Free image search engines
The advantage of these search engines for free images is that they (in theory) search multiple sites with free images at once. However, in practice some search just a handful of sites, rather than dozens. Anyway, it’s more than nothing but if you hope these image search engines are a blessing, you’d better get realistic.
It’s hard to compare the quality of the 7 search engines included in the article. At first I wanted to run the same queries through all of them and compare the results.
However, after I tried some very popular terms (‘computers’ in particular) and got thousands of results from some of the engines as well as no results for some not-so-popular terms (perhaps because I simply didn’t use the right keywords), I decided that such a test might give misleading results.
What’s more, these search engines index new images daily, so even if today there isn’t a single image for “sunny day”, tomorrow dozens of such images might get added. Therefore, I won’t be comparing the quality of the search for these 7 engines – I will just give my impressions with them, as well as some overall facts, such as the number of photos they include in the search or the sites they search.
Before we go on with the search engines themselves, is a word of advice. Even if the search returns images labeled as free for commercial use, always check the source site itself for the latest version of the license.
It’s quite possible that images that were once licensed as free, but that later the author had second thoughts and modified the license. Because of this, always check the license before you use the image.
1. Google Images
For many of us, Google Images is the first (and frequently the only) choice to find free images that are allowed for commercial use as well. To use Google Images, after you type your keywords in the search box and hit Enter, click the Images tab (1).
Then click on Search Tools (2) to open the search options and select Usage Rights (3). From the dropdown that opens, pick the license that suits you.
The selection with Google is usually good. For really popular terms it might be overwhelming. Fortunately, they frequently offer sub-results. For instance, for Computers they offer categories such as Apple, Laptops, Clipart, Wallpapers, Parts, PNG, etc. to narrow down the results.
For less popular terms and for less restrictive usage rights, the choice isn’t as extensive. Very often you won’t find anything suitable, especially if you are looking for material that is free to reuse with or without modification. In these cases it’s time to try another image search engine listed below. Hey, you didn’t lose much.
2. CC Search
CC Search, short for Creative Commons Search, is one more great search engine for images licensed under the Creative Commons licenses. Though technically they might not be a search engine, as they themselves state explicitly, they offer results for multiple other sites, such as Europeans, Flickr, Google Images, Wikimedia Commons, Fotopedia, Open Clipart Gallery, Pixabay.
The problem is that they don’t search all these sites at once. Rather, you enter your search string and choose the site where to search. This isn’t very convenient but still it’s faster than to search all these sites one by one.
In addition to images, CC Search offers results for music, videos, and other media as well.
You can specify what you are searching for – either stuff that is free for commercial use, or stuff you can modify, adapt, and build upon, or both.
If you like CC Search and you plan to use it all the time, they offer a browser add-on (at least for Firefox) to speed your access to the site.Keep in mind that Creative Commons isn’t a pseudonym for ‘free-for-all’. Take note of and honor all linking, accreditation and other usage conditions.
3. Photo Pin
Flickr is arguably the largest single repository of free images on the web, and it isn’t surprising that several image search engines focus on it exclusively. Photo Pin is one of these. When you open the site and enter your search string, you will see something like this:
On the left you can choose the License Type you are interested in (i.e. Commercial or Noncommercial), as well as how the results are arranged (Recent, Relevance, Interestingness).Of course, there’s nothing stopping you from searching Flickr for creative commons content directly via the advanced search facility. Photo Pin provides two advantages. Firstly it’s simpler, focussing only a licensable content. Secondly, Photo Pin makes downloading the correctly-sized image easy, and provides cut-and-paste credit links. A handy service indeed.
Unlike many of the other services that call themselves ‘search engines’, even though they search Flickr only, PicFindr is more ambitious. It searches more than a dozen of sites for free imagery under a range of licenses (Creative Commons, GNU, and others).
The list of sites includes the free sub-sections of some stock image sites, such as DreamsTime, which makes this search engine particularly useful. When you enter your search, you will see something like this:
Additionally, it has some useful advanced search options that make it even more useful.
Some of the sites included in the search aren’t very well-known and some of the popular ones are inexplicably missing, but all in all, this is a really good search engine.
If you are willing to try one more search engine that searches both Flickr and Wikimedia Commons, meet Veezzle. When you open the site and enter a search term, you can narrow it down, as shown in the next screenshot:
When you hit Search, the search results from Flickr and Wikimedia Commons are displayed separately in sets. You can choose how to visualize the results – by relevance, popularity, or upload date.
Even though Veezzle is another search engine built on top of Flickr, don’t discount it before you try it. Flickr is so huge and different search engines seem to return different sets of images, so it might turn out Veezzle can serve you the best images for a given serach term.
6. Every Stock Photo
With its almost 23 million free photos, Every Stock Photo is a really great place to search. They search multiple sites. In addition to Flickr and Wikimedia Commons that are to be found on other search engines, Every Stock Photo searches some other great places, such as MorgueFile, SXU, NASA, and Photi.
The advanced search options make search even better. They allow to choose the type of license, the source, and what to display (resolution, license, source). For me personally, Every Stock Photo is the second most preferred free image search engine after Google Images. But as tastes inevitably differ, this isn’t necessarily so for everybody else.
It might be that the search engine list up to this point is more than adequate, but here is the last one. Compared to some of the other search engines Behold is a poor relative as it lists results from Flickr only. However, unlike some of the other search engines, Behold is very, very fast, which is a huge usability plus.
Probably one last interesting feature that deserves mentioning is the ‘Look Like’ option. It allows you to fine-tune your search query, though when I tried it with my sample searches, I wasn’t particularly impressed by the results it retrieved.
These free images search engines can save you a lot of time when you are looking for useful images for your site, blog, or design project. However, none is perfect. Even the engines that index millions of photos can’t always return good results, even for not so obscure keywords.
Nevertheless, it makes sense to use a search engine instead of browsing sites with free images one by one.
Frequently Asked Questions (FAQs) about Image Search Engines
What are the key features to look for in an image search engine?
When choosing an image search engine, consider factors such as the size of the image database, the quality of images, the search filters available, and the licensing options. Some search engines offer advanced features like reverse image search, which allows you to upload an image and find similar images online. Others provide options to filter images by color, size, orientation, and more. Also, consider the licensing options available. Some search engines offer royalty-free images, while others require you to purchase a license.
Are there any free image search engines?
Yes, there are several free image search engines available. These include Unsplash, Pixabay, and Pexels, which offer high-quality, royalty-free images. However, it’s important to check the licensing terms of each image, as some may require attribution.
How does reverse image search work?
Reverse image search allows you to find similar images online by uploading an image. The search engine analyzes the uploaded image and searches its database for images with similar features. This can be useful for finding the original source of an image, identifying objects or people in an image, or finding higher resolution versions of an image.
Can I use any image I find on an image search engine?
Not necessarily. While some images are free to use, others may be protected by copyright laws. It’s important to check the licensing terms of each image before using it. Some images may require you to purchase a license, while others may require you to provide attribution to the original creator.
What is the difference between a regular search engine and an image search engine?
A regular search engine, like Google, searches the web for text-based content, while an image search engine specifically searches for images. Image search engines often have advanced features that allow you to filter images by size, color, orientation, and more.
How can I optimize my images for image search engines?
To optimize your images for image search engines, use descriptive file names and alt text, compress your images to reduce file size, and use high-quality images. Also, consider using structured data to provide more information about your images to search engines.
Are there any image search engines that prioritize privacy?
Can I use image search engines to find images for commercial use?
Yes, many image search engines offer images that are free for commercial use. However, it’s important to check the licensing terms of each image, as some may require you to purchase a license or provide attribution to the original creator.
How accurate are image search engines?
The accuracy of image search engines can vary. Some are very accurate, able to find exact matches and similar images with high precision. Others may not be as accurate, especially when searching for more abstract or complex images.
Can I use image search engines on my mobile device?
Yes, most image search engines are accessible on mobile devices. Some even offer mobile apps for easier access and use. However, the features and functionality may vary between the desktop and mobile versions.
