Frequently Asked Questions
Does Windows 11 have a built-in duplicate photo finder?
No. Windows 11 File Explorer and the default Microsoft Photos app do not have an automated duplicate finder tool. While you can manually sort files by name, size, or date, File Explorer cannot identify identical files with different names or visually similar pictures.
How can I find duplicate photos on Windows 11 without downloading third-party software?
You can use UnclutterPhotos directly in Microsoft Edge or Google Chrome on Windows 11. By using the HTML5 File System Access API, it securely scans any local folder or external drive in your browser, finding exact byte matches and similar burst shots 100% locally on your PC without software installation.
Why shouldn’t I rely only on File Explorer sorting to find duplicates?
Sorting by file size or date often misses duplicates that were renamed (e.g., "IMG_001.jpg" and "IMG_001(1).jpg") or photos saved with different compression settings from social media. UnclutterPhotos uses SHA-256 cryptographic hashing and perceptual visual comparison to catch every duplicate regardless of filename.
Is it safe to run photo deduplication in the browser on Windows 11?
Yes, it is completely secure. UnclutterPhotos runs in a local WebAssembly sandbox. Your pictures are never uploaded to any remote server or cloud database. Memory and disk operations stay strictly on your local PC.
Can I scan external SSDs and SD cards on Windows 11?
Yes. Connect your external drive, USB stick, or camera SD card to your Windows 11 PC, click "Select Folder" in UnclutterPhotos, and choose any directory on the external drive to begin scanning.
What happens to deleted duplicate photos on Windows 11?
When you confirm deletion in UnclutterPhotos, files are safely moved to the Windows Recycle Bin or deleted according to your browser permissions, allowing you to restore them if needed.
