About this app

Is your phone running out of storage? DupeCleaner is the smart, free duplicate photo finder and storage cleaner that helps you reclaim gigabytes of wasted space in minutes.

FIND & REMOVE DUPLICATE FILES
DupeCleaner uses advanced MD5 hashing to scan your entire photo library and find exact duplicate files. See duplicates grouped together, choose which to keep, and delete the rest with a single tap. Works with photos, videos, documents, and audio files.

SIMILAR PHOTO DETECTOR
Beyond exact duplicates, DupeCleaner uses perceptual hashing technology to find photos that look nearly identical — burst shots, slightly edited copies, and near-duplicates that waste your storage. Review them side by side and keep only the best.

WHATSAPP MEDIA CLEANER
WhatsApp downloads pile up fast. DupeCleaner scans your WhatsApp Media folder and organizes files by category — images, videos, documents, audio, and stickers. Quickly identify and remove forwarded memes, old videos, and files you no longer need.

LARGE FILE DETECTOR
Find the biggest files eating your storage. DupeCleaner sorts all files by size so you can quickly spot and remove large videos, downloads, and documents you forgot about.

STORAGE ANALYZER
Get a clear visual breakdown of your phone's storage with an interactive pie chart. See exactly what's taking up space — images, videos, audio, documents, apps, and more. Drill down into categories to find what to clean.

SMART CLEAN — ONE TAP CLEANUP
Don't have time to review every file? Smart Clean automatically identifies safe-to-delete items: exact duplicates, cached thumbnails, temporary files, and old WhatsApp media. Review the suggestions and clean everything with one tap.

SAFE TRASH SYSTEM
Accidentally deleted something important? No problem. All deleted files go to a trash folder with a 7-day recovery window. Restore any file before it's permanently removed.
