Initially I was using this tool and similar applications for other reasons but recently found it incredibly useful in identifying a few toys/kaiju I wasn't familiar with. I've submitted pretty low resolution images thinking I wouldn't get a hit but was impressed by the results. Simply upload an image and you can check matches across different search engines (Google, Bing, etc.). https://www.duplichecker.com/reverse-image-search.php Note: I was using the free version and found that to be sufficient. As noted, there are similar web applications that can perform the same task which might be worth giving a try if this one doesn't suit your needs. Hope this might help someone who needs it!
