Photo Deduplication for Exact and Similar Copies
Use the right comparison method for the duplicates you want to find.
Exact mode groups files with matching content fingerprints. Similar mode compares visual fingerprints to suggest burst shots, resized copies, or modest edits. Review every group before choosing what to remove.

Frequently Asked Questions
What is photo deduplication and how does it work?
Photo deduplication is the process of scanning and identifying identical files and visually similar images within a photo collection. UnclutterPhotos computes dual fingerprints—exact cryptographic hashes for identical copies and perceptual visual hashes for resized or burst shots—grouping candidates for review so you can delete unneeded copies while preserving originals.
Is there a free photo cleaner app that does not require downloading software?
Yes. UnclutterPhotos is a zero-install photo cleaner app that operates entirely inside modern web browsers like Chrome and Edge. It gives you the speed and power of desktop deduplication utilities with zero downloads and 100% privacy protection.
How does this compare to Duplicate Photos Fixer Pro?
While Duplicate Photos Fixer Pro requires installing desktop software and purchasing paid license keys, UnclutterPhotos provides instant in-browser scanning for local folders. Your photos never leave your machine, avoiding security vulnerabilities and malware risks.
What is the difference between exact and similar-photo detection?
Exact mode compares file-content fingerprints to identify matching files. Similar mode uses visual fingerprints to suggest images that may be related, such as burst shots, resized copies, or modest edits, so it requires closer review.
Which detection mode should I choose?
Start with exact mode when you only want identical file copies. Use similar mode when you also want to inspect visually related photos, and review each suggested group before removing anything.
Can similarity detection make mistakes?
Yes. Similarity matching is a suggestion system and can group photos that should both be kept. Sensitivity settings affect the tradeoff between finding more candidates and producing more false matches.
What file types are supported across exact and similar deduplication modes?
The main browser scanner currently supports JPEG, PNG, WebP, and GIF files. RAW, TIFF, BMP, and other specialist formats are not supported by the main scanner.
Are photos uploaded during deduplication?
No. Selected photo contents are processed locally for comparison and are not uploaded. Limited account, usage, analytics, licensing, and support data may be handled as described in the privacy policy.
