Deduplicate Files with Hashing

Identify duplicate files by comparing their SHA-256 hashes — identical content produces identical hashes.

Tip: SHA-256 and SHA-512 are cryptographically secure. SHA-1 is legacy and no longer recommended for security-sensitive use. All hashing runs locally in your browser — files and text are never sent anywhere.

Deduplication tips

🔁

Two files with the same SHA-256 hash have identical content, regardless of filename or modification date. Use this to find exact duplicates.

📁

Hash each version of a document to see if two "different" files are actually the same. Useful for auditing shared drives with redundant copies.

💡

For large-scale deduplication across thousands of files, use a command-line tool that hashes in bulk. This tool is best for spot-checking.

🖼️

Note: perceptual similarity (visually similar images) requires specialised tools. SHA-256 only detects exact byte-for-byte duplicates.
