MindGems Duplicate Image Finder
Duplicate photo finder "looks" at your photos to find similarities. Find look-alike and duplicate images in a folder, computer, network, or find duplicates in Adobe Lightroom. Organize photos by eliminating useless repeating pictures - save valuable disk space. Identify similar and duplicate images even if they are edited, rotated, flipped, or color-corrected. Specify percent of image similarity that will be used during the scan. It can broaden your results or specify exact match varying only in image format or size. After the scan process is finished the program shows all the duplicate images in groups and can automatically mark the smaller resolution and/or smaller file size images to be delete - the lower quality ones.

DuoBolt
DuoBolt is a high-performance desktop application for finding duplicate files and similar photos, on macOS and Windows.
Exact duplicates are proven byte-for-byte by a multi-threaded BLAKE3 engine — never filenames, metadata or heuristics — across folders, codebases, archives, external drives and NAS volumes, with uniform accuracy at any data size.
A second engine groups photos that merely look alike: bursts, edits, re-saves. AI Curation ranks each group and names every measure it used — face sharpness, exposure, eyes open, framing. It runs entirely on your machine: no upload, no account, no network.
The workflow is intentionally simple:
• Choose the locations to scan
• Review results with clear contextual grouping
• Remove only what you select — deletions go to the system Trash and can be reverted
Free to use. Every download starts with 7 days of Pro; afterwards DuoBolt keeps scanning and showing everything it finds, and caps only what a single operation can move.
