What is a Reverse Image Search and how do you do one?
Definition of “Reverse Image Search”
Reverse Image Search is a technique that allows you to take an image and find other images on the Internet that are identical, or nearly identical. With this information, you can find the source of the image, or even the name of the person if the image is a photo is of a human.
So, for example, if you search using the image of a logo and it comes back with a list of images that are very similar to the logo, it is a reverse image search.
The most common type of reverse image search uses visual similarities, which means that the search is only about how similar the images are visually. The idea is that if you see an image and you see that it looks similar to an existing one, there is a high chance that this image is related to it, so it’s a pretty reliable method for finding similar images.
Another method of reverse image search is textual similarity. This means that you are looking for similar images based on the content of the image and how they are similar to one another. This method works really well for searching based on the content of the image, but since it relies on text, not all images have text, so this isn’t a 100% accurate search.
Reverse Image Searching is possible with image files (JPEG, GIF, PNG), but it is most commonly done with JPEG files because the file format is most widely used on the Internet.
Why would someone need to do a Reverse Image Search?
For example, if you are looking to replace a logo and you don’t have a licensed one, you could do a reverse image search to find an image of the logo that you could license from a stock image database.
Do you want to know the name of the person in an image? If you are trying to identify a photo of a person, you could reverse image search with that photo and it could bring up a similar image from a social media profile of the person.
Do you want to know more about the image? If you are looking to know more about a subject, you can use a reverse image search to find related images that you could use to learn more about the subject matter in the image.
How to do a Regular Image Search
A normal image search is the process of searching an image using a keyword.
To perform a normal image search, first visit Google Images or another online image search engine. Input the desired type of image, for example “red cars”. You can also narrow your search by image size (larger/smaller), or image subject (sports, wildlife, etc.).
Then, select one of the images that come up on Google (or whatever site you are using). Look at the image. If you are looking for a specific image, now that you have a closer look, you may be able to narrow your search. Or, you may be able to eliminate the picture as being what you were looking for. If you are not sure, continue looking.
How to do a Reverse Image Search
Now that you know how to do a regular image search, let’s dive into how to do reverse searching.
In order to find reverse images, you need to use a service or program that is capable of finding images that are similar to the one you’re searching for. These services are all based on different search algorithms and are very different from each other. This is an important part of the process of reverse image searching. The right service and the right algorithm are what can help to get the best results.
In this tutorial, we will work with the most popular of these services: Google Reverse Image Search. This is also known as Google Search by Images.
- First, visit https://images.google.com in your web browser.
- Click the tiny camera icon to the right of the search field.
- Then, upload the image you wish to do a reverse search on.
Google will show you results if the image exists on the internet and Google knows the image URL.
Unfortunately, some of the time Google will not return the results you want, it just has no idea what the image is actually about. If this is the case, try another reverse image searcher such as:
