What to know before you begin
The similar-images mode uses visual comparison to surface candidates such as resized or edited photos. It is not equivalent to exact byte matching and requires human review. The project offers several scanning modes and the current version may place controls differently in Krokiet versus the older GTK GUI. Follow the meaning of the option you see, not just a screenshot from a different release.
For Windows, verify that your chosen folder is accessible and that the correct graphical frontend is running. The recommended approach starts with a small test set, especially when an action could rename, move, delete or link files.
Step-by-step: Does Czkawka detect pictures that look alike?
- Add the image folders you want compared.
- Open the similar-images tool and select a conservative difference threshold.
- Run the scan and inspect image previews side by side.
- Keep the highest quality original and check metadata before removal.
Important limitation
How to verify the result
Verify resolution and visual content of retained images after cleanup. A scan's estimated savings or the presence of a matching group does not by itself establish which copy should be discarded.
If the procedure does not match your screen, inspect the project's own FAQ and troubleshooting notes and identify the exact release and frontend first.
