Similar Photos Finder groups images that appear visually related. It can help review bursts and repeated compositions, but each image may still contain a meaningful difference.
Choose Almost Identical, Similar, or Broad Match according to how widely you want diCleaner to group results. diCleaner considers both the appearance and shape of each image, so changing the level can split or merge groups even when the folder has not changed.
Prepare the scan
- Back up irreplaceable photos.
- Download any cloud-only images you want compared.
- Open Files → Similar Photos Finder.
- Select an accessible image folder.
- Start the scan.
The first scan may take longer while diCleaner compares the images. Later scans of unchanged photos may finish faster. If you edit or replace a photo, diCleaner compares it again during the next scan.
Use the Photos app for assets managed inside a Photos library rather than modifying its package structure directly.
Compare a group
View images at a useful size and compare:
- Focus and motion blur.
- Facial expressions and closed eyes.
- Exposure and white balance.
- Crop and composition.
- Resolution and format.
- Edits, annotations, and metadata.
- Whether one is an original and another an export.
Choose what to keep
Preserve the best original and intentional variants. A lower-resolution image may still be the edited or shared version you need.
Remove cautiously
Delete a small group, verify the remaining files, and confirm that albums or projects still reference valid copies.
Similar Photos Finder looks for visual resemblance, not files whose contents are exactly the same. Use Duplicate Files Finder when you want to find exact copies.
