PDF Hygiene: Find & Remove Hidden Data Before You Publish
October 26, 2025
PDFs aren’t just “pictures on a page.” They can carry hidden data and active features—metadata, annotations, attachments, JavaScript—that leak author names, revision history, or even sensitive content. We walk through real-world failures (from court filings to government reports), explain the risks to privacy, deliverability, and compliance, and share practical, repeatable ways to audit and sanitize PDFs. Plus: tool-by-tool guidance (Canva, Word, InDesign) and a sysadmin playbook for site-wide audits and CI/CD automation.
