PDFCanon
Sanitize, normalize, and hash any PDF — deterministically
What is PDFCanon?
PDFs are structurally chaotic - same document, different bytes, hidden JS, broken audit trails. PDFCanon normalizes any PDF deterministically: strips active content, collapses structural noise, and returns a hardened document with a stable SHA-256 hash. Same input → same bytes → same hash. Every time. Free tier: 100/month. SDKs forNET, Node, Python, Java, Go.
