TinEye
tineye.com
Reverse image search engine that finds where an image appears online.
TinEye uses image fingerprinting to find every instance of an image across the web. Upload or paste an image URL and it returns matches sorted by date, size, or how closely they match — useful for tracking image origins and finding higher-resolution versions.
Why it is useful
The oldest and most specialized reverse image search. Unlike Google Images, TinEye focuses exclusively on finding exact and modified copies, making it more reliable for tracking image provenance.
