Google Search by Image
Google Reverse Search lets you search by images instead of keywords. Upload a picture from your desktop, tablet or mobile phone, and Google will show all the other web pages on the Internet that have similar images.
Reverse Search is useful for verifying the source of photographs, WhatsApp images, screenshots and memes. Tinder and Facebook users have used 'Search by Image' to research profile pictures of their potential dates while travellers use it for finding the photo's location.
