What This Tool Does
Photo Stack Finder finds photos that originate from the same source image:
byte-identical files, different resolutions (low-res vs. high-res), edited versions vs. originals,
rotation variants, format conversions (JPEG vs. HEIC), and cloud sync duplicates like
IMG_1234.jpg and IMG_1234(1).jpg.
Note: This tool does not find burst shots or similar photos from different moments (those are separate images, not duplicates).
Before You Start: Prepare Your Photos
- Export from cloud service (if needed):
- Google Photos: Use Google Takeout â Download all archives â Extract to a folder
- iCloud: Download via iCloud.com or iCloud for Windows
- OneDrive/Dropbox: Ensure fully synced to your computer
- Locate your photo directory - Where your photos are stored (can include subdirectories)
- Verify disk space - Need ~5-10% of photo collection size for analysis cache
- Backup (recommended) - Ensure you have a backup before deleting duplicates
Quick Start Checklist
