How to Check PDF Creation Dates, Metadata, and Document History
Question details
The user needs to inspect a PDF's metadata to determine its true creation date and identify any modifications, specifically to verify the authenticity of a dated document.
- Product
- Device & OS
- not provided
- Scenario
- Verifying document authenticity and origin dates for a potentially backdated or forged PDF.
- Observed behavior
- The PDF document claims to be from a past date, but the file characteristics suggest it was created much later.
Keep in mind that standard PDF metadata primarily reflects when the digital file or scan was created, not necessarily when the original paper document was drafted or signed. Metadata can also be manually altered.
View Document Properties and Metadata in PDF Software
Use the built-in document properties feature in your PDF reader to inspect basic metadata like creation date, modification date, and author.
This method allows you to view the standard metadata embedded in the PDF file. However, remember that if the PDF is a scanned copy of a physical document, the creation date will reflect the date of the scan, not the date the physical paper was signed or created.
Open the PDF document in Adobe Acrobat or your preferred PDF editor. Navigate to the top menu, select 'File', and click on 'Properties' (or use the keyboard shortcut Ctrl+D).
In the Document Properties dialog box, go to the 'Description' tab. Here you can view the file's Creation Date, Modification Date, the Application used to create it, and the Author.
Click on the 'Additional Metadata' button for a more comprehensive look at the document's hidden information, including advanced XMP metadata.

Frequently Asked Questions
Can PDF creation dates be faked or altered?
Yes, standard PDF metadata, including creation and modification dates, can be easily edited or completely removed using various software tools. Therefore, a basic creation date does not serve as definitive legal proof of a document's origin.
Why does the creation date show a recent year for an old document?
If an old paper document is scanned into a computer, the PDF creation date will reflect the exact moment the scanner created the digital file, not the date written on the physical paper.
How can I ensure a PDF's date and content are tamper-proof?
To guarantee a document's authenticity and lock its creation date, you must use cryptographic digital signatures issued by trusted certificate authorities or utilize dedicated document auditing systems at the time of signing.
Can I see a complete history of changes made to the PDF?
While the modification date tells you when the file was last saved, standard PDFs do not show a detailed version history or track specific text changes unless the document was signed with a digital certificate that explicitly tracks revisions.
