Pixiple

What Pixiple is

Pixiple is a free Windows desktop application for locating images that resemble one another and reviewing the results as sorted pairs. It compares pixel content with metadata such as dates, locations, and camera information. Filename, size, date, and format are ignored when similarity is calculated, and image paths are ignored by default. For side-by-side checking, synchronized zooming and panning keep views aligned, while a swap control helps compare image quality. Processing is multithreaded. Pixiple is portable as a single file, needs no installation, and saves no settings. It accepts formats handled by Windows Imaging Component, including PNG, JPEG, GIF, TIFF, and BMP. Dragging files or folders starts a scan, and the r5 release added a basic command-line interface. The project is open source under the MIT license. It requires Windows 7 or later and does not work on Windows XP. Matching is less effective after major pixel changes such as cropping or brightness, contrast, or saturation adjustments. Each new scan processes all images again because previous results are not cached.
