Reclaim space by scanning duplicate and near-identical photos, compressing oversized videos, and merging repeated contacts, all performed on-device. DupX: Storage & Photo Cleaner, from Lost Penguin Labs, targets Android users who need a privacy-focused maintenance tool. It includes swipe-to-clean gallery controls, a three-level video compressor with estimated savings, and automatic .vcf backups for contact merges, suited to photographers and anyone with large, cluttered media libraries.

It identifies exact duplicates and similar shots, then marks a best pick

DupX groups exact duplicate images and near-identical sequence shots, and marks a Best Pick for each set so you can decide quickly. The scanner also flags old screenshots and chat photos for review, which helps when a gallery contains many near-duplicate captures. These detection modes work locally on the device, so results appear without cloud uploads.

Background processing keeps your media private but requires storage permission

All file analysis runs on-device, which preserves privacy because no media or contacts leave the phone. DupX requests storage access to scan photos and videos, and contact permission to detect duplicate entries. The app creates automatic .vcf backups before merging contacts, providing a local restore point when you apply changes to the address book.

Swipe-first UI speeds cleanup, with an archive for reversible actions

The gallery uses swipe gestures, left to archive and right to keep, enabling rapid triage of large albums. Archived items are moved to an app archive rather than deleted, and you can restore them until you empty the archive; emptying is gated behind the Pro tier. The three compression presets, Low, Medium, High, show estimated file sizes before you start.

Free scanning and Pro-level execution separate review and destructive actions

Scanning and review functions remain available in the free tier, including grouped duplicate previews and limited contact merges. The Pro version is required to delete photos and videos, empty the archive, compress videos, and perform unlimited merges, which splits review from execution and reduces accidental data loss during browsing.

Recommended for privacy-conscious Android users who want cautious storage cleanup

DupX suits anyone who prefers local-only processing and a gesture-driven workflow: it detects duplicates, archives items for recovery, and backs up contacts to .vcf before merges. The main trade-off is that destructive actions and unlimited merges are behind the Pro tier, so plan to use the archive and backups while you confirm results before committing deletions.
