💡 Frequently Asked Questions
What hidden data is stored inside PDF files?
PDF files frequently embed the author full name, company name, computer operating system version, software used to create it (e.g. Word, Acrobat, InDesign), and complete editing timestamps in hidden Info and XMP metadata streams.
Will sanitizing metadata alter the visible text or layout of my PDF?
No. The visible document text, pages, fonts, and graphical layout remain 100% untouched. Only the invisible metadata streams are rewritten.
Is this compliant with GDPR Article 25 (Privacy by Design)?
Yes. By stripping unneeded personal identification before distributing documents, you satisfy data minimization principles required under GDPR, HIPAA, and corporate confidentiality policies.
Can large multi-page PDF documents be sanitized?
Yes, our client-side engine processes multi-page documents quickly within your browser local memory limits.
Is any file data transmitted over the internet?
Zero bytes are transmitted. All document processing takes place entirely on your device using client-side JavaScript.
