Why Use Our Secure PDF Metadata Extractor ?
Every time a PDF is created or modified, hidden information-known as metadata – is embedded within the file’s internal code. This data can include the original author’s name, the specific software or tool used to create the document, exact creation and modification timestamps, and hidden security permissions. Whether you are a digital forensics investigator analyzing document authenticity, a student checking file properties, or a professional ensuring no sensitive personal data is leaked before sharing a file, our PDF Metadata Viewer gives you total visibility into your document’s hidden digital footprint.
Privacy is our top priority. Unlike other online PDF readers that require you to upload your sensitive files to a remote cloud server-risking severe data breaches – our tool operates entirely on client-side technology. Using the powerful PDF.js library, the extraction process happens locally inside your device’s memory. Your documents never leave your computer, ensuring absolute confidentiality and lightning-fast processing speeds, even for massive 100MB files.

The viewer extracts standard document properties (Title, Author, Subject, Keywords), creation details (Creator Tool, Producer, exact timestamps), and advanced technical data (total pages, dimensions, PDF version, encryption status, permissions, and JavaScript flags).
Why does the tool output a JSON file when I download the report?

Can this tool modify or remove the metadata from my PDF?
No, this specific tool is designed strictly as a “Viewer” to safely extract and display information without altering your original document. Your source file remains completely unchanged.
