Exact duplicate photo search

Find files that represent the same underlying image rather than relying only on the filename.

Near-duplicate image search

Detect visually similar copies that may have been resized, recompressed, renamed or saved in another supported image format.

Useful for mixed local libraries

Duplicate Search is designed for real working folders where exports, alternate resolutions and copied files may sit alongside source images.

Review before acting

Use N1 browsing, Gallery and comparison tools to inspect candidates before deciding what to keep.

Duplicate cases

  • Same image with a different filename
  • Different compression or resolution
  • Copies saved in another format
  • Visually similar duplicate variants

Part of the full N1 workflow

These tools sit alongside Gallery, Filmstrip, culling, comparison, metadata editing and color management. See the N1 Viewer overview for the complete feature set.
