Every PDF file carries invisible data you might not know exists — and it can reveal far more than you intend when shared.
The name of the person or organisation that created the document — often pulled directly from your OS account name.
Exact timestamps showing when the document was first created and last edited, including timezone info and revision history.
Which application generated the PDF — Adobe Acrobat, Microsoft Word, LibreOffice, macOS Preview, or others — exposing your tech stack.
Advanced XML-based embedded data that can hold company names, document IDs, copyright claims, camera settings, and custom enterprise fields.
Tags and category descriptors embedded by document management systems that can expose internal filing structures and classification schemes.
Encryption status, access restrictions, digital signature presence, AcroForm state, and PDF/X conformance markers.
A complete metadata toolkit packed into a single, private, browser-based tool — no installation required.
Reads all standard and non-standard PDF metadata — Info Dictionary, XMP packet, document properties, permissions, and custom application fields.
Automatically evaluates your PDF's metadata exposure and assigns a High / Med / Low risk rating with detailed per-field explanations.
Choose exactly which categories to strip — author, dates, title, software, XMP packets, custom fields — or wipe the entire metadata dictionary at once.
Directly deletes keys from the raw PDF Info Dictionary rather than just setting empty strings — ensuring metadata is truly gone, not merely blanked.
Removes the full XMP XML stream and Adobe's PieceInfo private metadata block from the document catalog — fields other tools often miss.
Download all detected metadata as a structured JSON file or formatted plain-text report for compliance documentation and auditing.
Instantly search and filter through hundreds of metadata fields using the real-time search bar — find any field in under a second.
All processing runs entirely in your browser via JavaScript. Your PDF never touches a server. No tracking, no storage, no data collection.
Three simple steps to inspect and permanently clean your PDF's hidden information.
Drag & drop your PDF onto the upload zone above, or click "Browse PDF" to select it from your device. No size limit beyond your browser's available memory. Your file never leaves your device.
Use the tabs to explore every embedded field: the View Metadata tab shows all fields organized by category with live search; Security Analysis scores your privacy risk; and Raw JSON gives you the complete machine-readable output.
Open the Remove Metadata tab, tick the categories you want erased, then click "Remove & Download Clean PDF." You receive a completely cleaned PDF instantly — straight to your downloads folder.
Before or after removal, download the full metadata as a .json or .txt report from the View tab. Useful for compliance records, legal discovery, or digital forensics documentation.
Hidden metadata can expose sensitive information about you, your organisation, and your workflow. Here's what's at stake.
Your full name and username can be embedded in every PDF you create. Remove it before sharing externally to prevent unintended identity disclosure.
Internal software names, network paths, company details, and document management IDs can leak through PDF metadata and reveal your infrastructure.
Exact creation and edit timestamps expose your working hours, timezones, and revision cadence — sensitive in negotiations and legal proceedings.
Data protection regulations including GDPR require minimising personal data in shared documents. Metadata-clean PDFs keep you compliant.
Journalists, whistleblowers, and researchers use metadata removal to prevent digital fingerprinting and protect sources from identification.
Publishers, designers, and agencies strip metadata from client deliverables to prevent proprietary workflow details from reaching competitors.
