Image Duplicate Finder

Find visually identical or near-duplicate images in a folder.

How to use Image Duplicate Finder

  1. Upload a folder or many images.
  2. Wait while each image is hashed.
  3. Review the duplicate groups.
  4. Delete or mark for cleanup.

What is Image Duplicate Finder?

Image Duplicator Finder scans a folder of photos and groups visually similar ones together using a perceptual aHash. It catches duplicates even after resizing, recompression, or format conversion - not just byte-for-byte copies.

Who is Image Duplicate Finder for?

Photographers cleaning up burst-mode shoots, digital archivists deduplicating libraries, marketers auditing image assets, and anyone reclaiming disk space.

Why use Image Duplicate Finder?

  • Detects near-duplicates, not just identical bytes.
  • Adjustable similarity threshold.
  • Groups every match visually side by side.
  • Runs 100% in your browser.

When should you use Image Duplicate Finder?

Cleaning up a photo library, deduping product catalog images, spotting reuploads across a media set, or auditing website assets before optimization.

Is Image Duplicate Finder safe?

All hashing runs locally - filenames and pixel data never leave your device.

Tips for best results

  • Threshold 4-6 catches true duplicates cleanly.
  • Raise the threshold to catch heavily edited variants.
  • Use Image Hash Generator to inspect a specific file's hash.
  • Batch large folders - hashing runs in the background.

Frequently asked questions

How do 'near-duplicates' get detected?

We generate a perceptual hash (pHash) for each image, then group images whose hashes differ by fewer than N bits. That catches resized, re-encoded and lightly-edited versions of the same photo.

Is my image uploaded to a server?

No. Every ImageEditPro tool processes your image directly inside your browser using JavaScript and the Canvas API. Files never leave your device, so your photos stay 100% private - even when you're editing sensitive documents or personal photos.

Is it really free? Any watermark or signup?

Yes, completely free. No account, no sign-up, no watermark, no daily limit. ImageEditPro is supported by unobtrusive ads so you can use every tool as many times as you need without paying.
