Duplicate Image & Similar Image Finder
Find exact duplicates or visually similar images within a batch. Clean up your hard drive or server by identifying redundant files using perceptual hashing.
Smart Image Deduplication
Finding duplicate images by file name or file size doesn't work if one image was resized or saved in a different format. This tool uses Perceptual Hashing (pHash) to analyze the actual visual content of the images. It generates a digital fingerprint for each photo, allowing it to accurately flag images that look identical, even if they have different resolutions or file names.
Why Use Our Duplicate Image Finder?
- Visual Matching: Finds duplicates even if one was resized or compressed.
- Saves Storage Space: Identify and delete redundant files.
- Browser Based: Processes your personal photo batches locally.
- Fast Hashing: Compares dozens of images in milliseconds.
How to Use the Duplicate Image Finder
Upload a batch of images (e.g., 10 to 50 photos).
Click 'Scan for Duplicates'.
The tool generates hashes and compares the visual data.
Review the flagged groups of identical or highly similar images.
Frequently Asked Questions
Slight cropping may change the perceptual hash enough that it isn't flagged as a 100% match. The tool is best at finding identical images that were simply resized or reformatted.
No! The perceptual hashing algorithm is written in JavaScript and runs entirely inside your browser. No photos ever leave your computer.
