Find duplicate photos in your browser
DupShelf is a privacy-focused, browser-based tool designed to identify and manage duplicate photos without uploading any data to the cloud. Unlike many duplicate finders that require uploading your entire library or rely on fuzzy matching algorithms, DupShelf runs entirely within your browser, ensuring your images never leave your device. It scans folders directly or allows batch additions, using SHA-256 hashing to detect exact duplicates—even if the files have been renamed or re-exported. The interface enables users to review matched groups, select which images to keep, and organize duplicates by moving or exporting them, all without auto-deletion. Perfect for messy backups, downloads, or photographers who prioritize privacy and control, DupShelf offers a straightforward, secure solution for managing photo collections efficiently and confidently.
