Most duplicate tools upload your library or push "similar" matches. DupShelf runs entirely in your browser—photos never leave your device. Scan a folder (Chrome/Edge) or add batches. Exact duplicates are grouped by file content (SHA-256), so renamed copies and re-exports still match. Review groups, choose keepers, move extras to a subfolder or export CSV. DupShelf never auto-deletes. Free, no account, no upload—built for messy backups and downloads.
Hey Product Hunt 👋
I built DupShelf after repeatedly finding the same shots across Downloads, phone exports, and backup folders always with different names.
What’s different:
• 100% in the browser—no upload, no account
• Exact duplicates (same file bytes), not vague “similar” guesses
• You choose keepers; we move to a folder or export CSV we don’t delete for you
Best experience: Chrome/Edge + “Choose folder” for a full library. Mobile works via “Choose images” in batches.
Try the workbench: https://dupshelf.renderlog.in/app
I’d love feedback on speed on large folders and whether the move/export flow feels safe enough before you delete anything on disk. Happy to answer questions all day!
Running a duplicate photo finder entirely in the browser memory is a huge win for privacy. Most tools force you to upload assets to a cloud server or install heavy desktop packages. How does it handle performance and processing speed when a user drops in a massive folder with thousands of high resolution images?
