# PDFs and slide decks are harmful data storage formats.

Organizations treat PDFs, formatted Word docs, and slide decks as the standard way to store institutional knowledge. The author argues these formats are actively harmful to AI integration and should be relegated strictly to 'outputs' for human reading, not sources of truth. See [[concept-human-formatted-data]] and [[quote-pdfs-are-outputs]].

**Challenges:** the standard corporate practice of using PDFs and slide decks as the primary medium for storing and sharing institutional policies and knowledge.

**Balanced view (enrichment):** PDFs and slides remain critical for human communication, compliance, and archival. They are poor *canonical* sources of truth for agents but not inherently harmful if backed by machine-readable mirrors and used as human-facing outputs. The prescriptive stance is directionally correct for AI readiness but somewhat overstated.
