I used to use DupeGuru which has some photo-specific dupe detection where you can fuzzy match image dupes based on content: https://dupeguru.voltaicideas.net/ But I switched over to czkawka, which has a better interface for comparing files, and seems to be a bit faster: https://github.com/qarmin/czkawka. - Source: Hacker News / 12 months ago

I used DupeGuru (https://dupeguru.voltaicideas.net/) in the past but I'm not sure it's the best solution for you. Try it, it's open-source. - Source: Hacker News / about 1 year ago
