Bulk PDF Metadata Scrubber Privacy Protection Engine
When you export a PDF, software like Word, InDesign, or Acrobat silently attaches hidden metadata—including your name, operating system, exact creation dates, and editing software. This tool parses the raw binary structure of your documents to permanently annihilate all hidden dictionaries, ensuring absolute privacy before sharing.

How the PDF Scrubber Engine Works
Standard PDF files are built using an intricate dictionary object structure. When you save a file, the generating software injects an "Info Dictionary" block. This block quietly logs sensitive properties including the Author, Creator (the application used), Producer (the PDF conversion tool), and precise UTC CreationDate and ModDate timestamps.
This tool utilizes a local binary parsing library to deconstruct your PDF without communicating with any external servers. It navigates directly to the embedded Info Dictionaries and overwrites the metadata strings with empty byte buffers. It then resets the internal creation timestamps to the Unix Epoch (Jan 1, 1970) to eliminate timezone and temporal tracking. Finally, it serializes the document back into a standard PDF structure.
The actual visual pages, text vectors, and images inside the PDF remain completely untouched. Only the invisible metadata headers used for tracking and classification are annihilated.
Frequently Asked Questions
Yes. The visual rendering data (text, fonts, images, vectors) is stored in a separate object stream from the metadata. Scrubbing the metadata dictionaries has zero impact on how the PDF displays in Adobe Acrobat, Chrome, or physical printouts.
Absolutely. Because this application operates strictly as a client-side JavaScript tool, your PDF files are processed within your device's memory. The files are never uploaded, transmitted, or logged on any external servers, guaranteeing total data sovereignty.
No. This tool specifically targets Document Properties (Title, Author, Subject, Keywords, Creator, Producer, CreationDate, ModDate). It does not alter visual redactions, annotations, or OCR text layers embedded within the page arrays.
