JPEG, PNG, GIF, WebP, or BMP. Add several listing photos to compare.
    Higher = treat more pairs as “similar.” Lower = stricter matches.

    Sorting similar photos efficiently

    Near-duplicate detection is useful for product catalogs, real-estate listings, and photo libraries where the same scene appears many times with small changes. The tool helps group almost-identical images so you can choose the best one instead of scrolling through repeated copies by hand.

    Review clusters before deleting

    Similarity scores are helpful, but they are not a substitute for a human review. A cropped version, a resized version, and a genuinely different shot can look close enough to the algorithm to land in the same cluster, so confirm each group before removing files.

    Seller quality control

    Before uploading a catalog, group near-identical shots so customers see variety instead of the same angle repeated five times.

    What near-duplicate means

    Algorithms approximate similarity — review groups visually before deleting.

    Catalog hygiene

    Marketplaces penalize repetitive gallery photos. Grouping near-duplicates before upload helps you pick the sharpest angle and delete redundant shots that add no buying information.

    Threshold judgment

    Similar lighting and white-background product shots cluster tightly; lifestyle photos with models may split into separate groups even when the SKU matches.

    Quick start

    1. Add listing photos — Select a folder of product or catalog images from your machine.
    2. Run similarity scan — Perceptual hashing groups near-duplicate and resized copies.
    3. Review groups visually — Confirm clusters before deleting — algorithm scores are approximate.
