About this tool
A backup collection may contain exact copies and resized versions of the same picture. Review the two kinds of match separately and decide which file fits your needs; originals are never deleted automatically.
How to use
Find duplicate images
What this tool is for
Find exact copies with file hashes and visually similar images with perceptual difference hashes, then recommend a version to keep by resolution and file size.
How to use it
Select the collection to audit: file hashes find byte-for-byte duplicates, while perceptual difference hashes group visually similar images. Review the suggested keeper by resolution and size; the tool never deletes local files.
Results and next steps
The primary result is a structured report with the necessary previews and copyable values. It supports decisions but never deletes or overwrites local files.
Privacy and local processing
Processing runs in your browser. Source images are not uploaded by this tool.
Common questions
How do exact duplicates differ from visually similar images?
SHA-256 compares file bytes; dHash and the chosen threshold compare appearance. Cropping or rotation can affect similarity. Keeper suggestions rank pixel dimensions and file size rather than judging true sharpness, and never delete your local originals.
What happens to videos, documents or ZIPs inside a folder?
Folder import skips unsupported non-images without charging them to the image-size budget and does not expand ZIPs inside the folder. Select a ZIP separately to inspect it. Split large folders into batches, remembering that comparisons cover only the current batch.
How should I set similarity sensitivity without losing distinct photos?
A higher threshold includes pairs with greater visual differences. Start low, inspect the groups and raise it only as needed. Burst shots may differ in expression or sharpness; keeper suggestions do not replace your judgement.
