Free Online Image Hash Generator – Detect Duplicate Images Using dHash & aHash

What is Image Hashing?

Image hashing generates a fixed-length hash based on the visual appearance of an image. Unlike cryptographic hashes (like MD5 or SHA), perceptual hashes help identify visually similar or duplicate images — even if they’re resized or slightly edited.

The two most popular types:

  • dHash (Difference Hash): Captures edge gradients and differences

  • aHash (Average Hash): Calculates average pixel brightness

These are ideal for reverse image searches, deduplication, and content validation.

🛠️ Features of This Tool:

✅ Upload JPG, PNG, WebP images
✅ Generates both dHash and aHash instantly
✅ Fast hash computation in-browser
✅ Copy hash to clipboard
✅ Mobile and desktop compatible
✅ No signup, no watermark, no tracking

Whether you're building an app or curating image libraries, this tool saves you hours of manual work.

How to Use It:

  1. Go to the Image Hash Generator Tool

  2. Upload your image

  3. View the dHash and aHash values

  4. Use the hashes to detect or compare duplicates programmatically

The hash can then be stored in databases, compared with other hashes, or integrated into image search systems.

Who Is It For?

  • 🧑‍💻 Developers – Implement duplicate detection logic in apps

  • 📸 Photographers – Sort or deduplicate similar shots

  • 🧠 Researchers & Data Scientists – Organize large image datasets

  • 🏢 Content Managers – Avoid re-uploading duplicates
