Frequently Asked Questions about PDF Sanitization
What hidden metadata is stored inside a PDF?
▼
A PDF typically stores the author username, exact software and OS versions (Word, macOS, Acrobat), local hard drive folder paths, precise timestamps of creation and modification, and sometimes GPS coordinates or scanner serial numbers.
Why is it risky to share unsanitized PDF documents?
▼
In legal proceedings, corporate negotiations, or investigative journalism, metadata can reveal who actually drafted a contract, the real time a report was completed, or the identity of a confidential source.
Are my files uploaded to any servers for sanitization?
▼
Never. Sanitization is performed 100% inside your browser's local RAM using JavaScript and WebAssembly. Your confidential documents never leave your machine.
Does sanitizing alter the visible text of the document?
▼
No. Visible text, typography, layouts, and graphics remain completely untouched. Only the invisible metadata layer embedded in the file stream header is destroyed.
