What data is hidden in your PDF?
PDF files contain a dictionary of information that isn't always visible in standard PDF readers like Adobe Acrobat or Chrome. This inspector reveals the raw data layer.
- Basic Info: Title, Author, Subject, Keywords
- Origin: Creator Tool (e.g., MS Word), Producer (e.g., Quartz PDFContext)
- Dates: Creation Date and Modification Date
- Tech Specs: PDF Version (e.g., 1.4, 1.7), File Size, Page Count
Why check metadata?
Verify Authenticity: Check creation dates to see if a document was backdated.
Software Forensics: Identify what software was used to generate the file.
Privacy Check: Ensure your name doesn't appear in the "Author" field before sharing anonymous documents.
Understanding Digital Signatures
If our viewer detects a signature, it means the file contains a cryptographic hash verifying its contents. Note that this viewer only checks for the presence of a signature flag. To validate if the signature is still trusted or if the certificate has been revoked, you must use Adobe Acrobat Reader.
Warning: If you use our "Edit" or "Clean" tools on this file, the signature will be removed to allow modification.
