Sakarto offers 7 distinct visual algorithms for finding duplicate images and videos. We break down when to use Color Signature, pHash, ORB, and the rest—so you never waste time on the wrong tool again.
Upload a reference image or video and Sakarto finds every similar copy in a folder. 7 algorithms explained—Color Signature, aHash, BlockHash, dHash, pHash, wHash, and ORB. Reference pinned, protected, and ready to compare.
Sakarto's pHash (Perceptual Hash) algorithm finds duplicate photos and videos using the same Discrete Cosine Transform as JPEG compression. Perfect for re‑compressed, watermarked, and lightly edited copies. Free, browser‑based, and 100% private.
