Image Matcher

Upload images, zip archives, or paste image URLs to find exact and near-duplicate matches using perceptual hashing. Use in-group mode to find duplicates within one set, or source vs dataset to match a smaller set of reference images against a larger collection.

Matching mode

In-group — find all matching pairs within one set

Source vs Dataset — match reference images against a larger set

Upload images

Select multiple image files or a .zip archive. Up to 20000 images.

Or paste image URLs (one per line)

Or upload a file of URLs

CSV (auto-detects url/image_url/media_url/link column) or plain text with one URL per line.

Hash distance threshold

0 = exact matches only. Higher values allow more variation (try 5–15 for near-duplicates).
