Best app for removing duplicate photos

AI summary

Remo Duplicate Photos Remover is the best default for cross-platform duplicate cleanup; choose Apple Photos or Files by Google when you prefer a built-in free tool for exact matches. For advanced AI-powered sorting of similar shots, blurry images, and burst photos on iOS or Mac, Gemini Photos or Gemini 2 are great alternatives, though they require a subscription for full access. On desktop computers, tools like Cisdem Duplicate Finder or dupeGuru provide powerful scanning capabilities for large photography libraries, while Slidebox offers manual swipe-based sorting for users nervous about automated deletions.
