Image Hash Generator

Generate MD5, SHA-256 and perceptual (pHash) hashes for any image.

How to use Image Hash Generator

  1. Upload your image.
  2. See all hashes (MD5, SHA-1, SHA-256, pHash, dHash).
  3. Copy any hash with one click.
  4. Optionally batch-hash many files.

What is Image Hash Generator?

Image Hash Generator computes both a perceptual aHash (64-bit) and a cryptographic SHA-256 for your image. Perceptual hashes let you find visually similar images even after resize or recompression, while SHA-256 verifies exact byte-level identity.

Who is Image Hash Generator for?

Digital forensics analysts detecting duplicates, photographers spotting reuploaded work, content moderators fingerprinting media, and developers building deduplication pipelines.

Why use Image Hash Generator?

  • Two hash types: perceptual + cryptographic.
  • One-click copy for both hashes.
  • Instant computation.
  • Runs privately in your browser.

When should you use Image Hash Generator?

Auditing whether two images are the same file, detecting near-duplicates in a photo library, or generating stable image IDs for a database.

Is Image Hash Generator safe?

Hashing happens locally - the file bytes never leave your device.

Tips for best results

  • aHashes stay similar even after resizing - great for near-duplicate detection.
  • SHA-256 changes if even a single byte changes.
  • Compare two aHashes with Hamming distance for similarity scoring.
  • Use Image Duplicator Finder to scan folders.

Frequently asked questions

What's the difference between MD5 and pHash?

MD5/SHA-256 change completely if a single byte changes. Perceptual hashes stay similar for visually similar images, so they can detect resized or re-encoded duplicates.

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.
