What is PDF Hash & Fingerprint Generator?
PDF Hash & Fingerprint Generator is a free, on-device tool that computes cryptographic hashes (MD5, SHA-1, SHA-256, SHA-384, SHA-512) over the original bytes of any PDF, plus a content fingerprint that normalizes away harmless metadata differences. It is useful for integrity checks, comparing document versions, and proving that two PDFs carry the same underlying content. Everything runs locally in your browser — nothing is uploaded.
Common Use Cases
Verify file integrity
Confirm a downloaded PDF exactly matches the original by comparing its SHA-256 hash with the publisher-issued checksum.
Track document versions
Record the content fingerprint of each version so you can quickly confirm which draft a PDF corresponds to, regardless of renaming.
Prove content is identical
The content fingerprint ignores metadata and history, so two files with different titles or producers but identical page content match.
Audit / archival workflows
Store per-file hashes in a manifest to detect accidental tampering or corruption later.
How to Use This Tool
- Drop a PDF (up to 100MB) onto the upload zone or click to browse
- Hashes are computed over the original file bytes instantly; page count and first-page dimensions are read best-effort
- Review the MD5, SHA-1, SHA-256, SHA-384 and SHA-512 rows — legacy algorithms carry a warning badge
- Read the content fingerprint (SHA-256) for a metadata-independent check of the document content
- Copy every hash at once or download a plain-text .txt report of all values
