Know what an image is, even after the filename changes.

Image Tagger is a local, non-destructive image viewer and catalog that tracks images by content identity instead of treating paths and filenames as identity.

Local by design

Original images stay on your filesystem. SQLite stores content identity, locations, tags, collections, viewer state and analysis results.

Identity survives moves

SHA-256-backed identity keeps catalog knowledge attached to the bytes through renames, moves, copies and duplicate locations.

AI without surrendering the library

Optional WD v3 ONNX auto-tagging runs locally, checkpoints work by content identity and keeps uncertain non-people suggestions pending for review.

A viewer that also understands the collection

Browse, sort, search, collect, compare, rename, move, trash and tag images without turning the image files themselves into a metadata dumping ground. Image Tagger separates the image from the catalog knowledge about the image.

The result is a practical image-management tool for large local libraries where names, directories and organization evolve over time.
