Image Comparator

Image Comparator is a robust Windows desktop application designed to identify and manage duplicate or visually similar images using advanced Discrete Cosine Transform (DCT) algorithms. Unlike standard comparison tools, it effectively detects images that have been resized, compressed, or slightly modified.

Features

Smart Detection: Uses perceptual hashing to find both exact duplicates and similar photos across recursive folders.
Visual Review: Inspect matches with a detailed side-by-side previewer featuring zoom and pan controls.
Broad Support: Compatible with JPEG, PNG, BMP, GIF, TIFF, and ICO formats.
Safe Management: Delete files permanently or safely send them to the Recycle Bin. You can also mark false positives to ignore them in future scans.
User Friendly: Features a modern WPF interface with drag-and-drop support and 19 available languages.
