What is Karma Decay?
Karma Decay is a free, Reddit-specific reverse image search. Upload an image or paste a URL and it searches Reddit to see whether that image has been posted before, showing the subreddits, post titles, and scores where it appeared. Because it indexes only Reddit, it can do this faster and more specifically than general reverse-image tools.
Key Features
- Reddit reverse image search: Find where an image has appeared on Reddit.
- Cross-subreddit: Surfaces matches across communities.
- Repost and OC checking: See whether something is a repost or original.
- Free: No account needed.
Is Karma Decay Worth It?
Karma Decay is a niche but genuinely useful free tool for spotting Reddit reposts, and it is still listed among working reverse-image tools in 2026. It is old and can be slow, it only covers images (not text), it does not index every Reddit image, and heavily edited or cropped versions can slip past it. For a quick repost check before posting, or for mods policing originality, it does the job.
