What is Reverse Image Search?

Reverse image search is a technique that allows you to take an existing image file and perform a search to find matching or similar images online. It works by analyzing the visual attributes of the image like color, shape, texture, layout, objects, etc. and comparing it against image databases to find relevant results.

This can be extremely useful in many scenarios:

• Finding the original source or context of an image you have saved - great for fact checking or giving proper attribution.
• Locating modified versions like edits, memes or artistic renditions of an image.
• Getting inspiration for creative projects by discovering visually similar stock photos, illustrations or artwork.
• Detecting unauthorized usage of your images or brand assets on other sites.
• General image recognition and search capabilities.

Some popular reverse image search services are Google Images, TinEye, Yandex, Bing and KarmaDecay. Most provide browser extensions or mobile apps to easily search by image from any webpage. Paid offerings provide additional capabilities like searching private corporate image databases.

Overall, reverse image search gives you more insight into where an image originated and how it spread across the internet. It's a versatile tool for brand monitoring, fact checking, art inspiration and more.
