PDF Creator and Producer Metadata Explained

Every PDF contains Creator and Producer metadata fields that reveal information about how the document was made. Understanding these fields is important for both forensics and privacy.

What Is the Creator Field?

The Creator field identifies the application that created the original content that was converted to PDF.

Examples

What It Reveals

• Original software - What was used to author the content
• Organization clues - Enterprise software vs. consumer tools
• Workflow information - How documents are created

What Is the Producer Field?

The Producer field identifies the software that actually created the PDF file.

Examples

What It Reveals

• PDF creation method - How the PDF was generated
• Software version - Specific versions can indicate vulnerabilities
• Processing history - If different from Creator, document was converted

Creator vs. Producer: The Difference

When They Match

If a document was created directly as a PDF in Adobe software:

• Creator: Adobe InDesign CC
• Producer: Adobe PDF Library 15.0

Both indicate Adobe was used throughout.

When They Differ

If a Word document was converted to PDF:

• Creator: Microsoft® Word for Office 365
• Producer: macOS Version 12.0 Quartz PDFContext

This shows Word created the content, but macOS created the PDF.

Multiple Productions

If a PDF was edited after creation:

• Creator: (original application)
• Producer: (last software to modify the PDF structure)

Privacy Implications

What These Fields Can Reveal

1. Software inventory - What programs you use
2. Operating system - Often embedded in Producer
3. Software versions - Potentially exploitable
4. Organization type - Enterprise vs. personal tools
5. Workflow information - How documents are processed

Real Examples

Forensic Uses

Detecting Anomalies

Compare Creator/Producer with expected values:

Expected for official documents:

• Enterprise document management systems
• Professional publishing software
• Consistent organizational standards

Suspicious for official documents:

• Consumer image editors
• Generic online converters
• Inconsistent software choices

Tracking Document History

Multiple Producer entries (visible in detailed metadata) can show:

• Each software that modified the PDF
• Processing sequence
• Potential tampering indicators

How to View Creator/Producer

In Adobe Acrobat/Reader

1. File → Properties
2. Description tab
3. See "Application" (Creator) and "PDF Producer"

In Preview (Mac)

1. Tools → Show Inspector
2. General tab

Command Line

Using ExifTool:

exiftool -Creator -Producer document.pdf

Using pdfinfo:

pdfinfo document.pdf | grep -E "(Creator|Producer)"

How to Remove Creator/Producer

Why Remove Them

• Privacy - Don't reveal your software stack
• Security - Don't expose version information
• Professionalism - Clean metadata for distribution

Using Sanitization

CleanPDF and similar tools remove Creator and Producer along with other metadata:

1. Upload to CleanPDF Sanitize
2. All metadata is removed
3. Download clean file

Note: The sanitization tool itself may become the new Producer. This is normal and expected.

Using Adobe Acrobat

1. File → Properties → Additional Metadata
2. Clear fields manually
3. Or use Tools → Redact → Sanitize Document

Common Patterns

Direct PDF Export

When content is created directly as PDF:

• Creator and Producer often from same vendor
• Indicates native PDF workflow

Conversion

When content is converted from another format:

• Creator shows original application
• Producer shows PDF converter

Editing

When an existing PDF is modified:

• Creator may remain from original
• Producer changes to editing software

Print to PDF

When using print-to-PDF:

• Creator shows the printing application
• Producer shows the PDF print driver

Special Cases

Scanned Documents

• Creator: Often the scanning software
• Producer: The PDF creation component

Web Capture

• Creator: The browser or capture tool
• Producer: PDF generation library

Merged Documents

• May show Creator/Producer of the merge tool
• Original document metadata may be lost

Conclusion

Creator and Producer metadata provide valuable information about PDF origins:

Creator tells you what made the content. Producer tells you what made the PDF.

Together, they reveal:

• Document workflow
• Software used
• Potential anomalies

For privacy and security:

• Consider removing before sharing
• Analyze in forensic investigations
• Match expectations for document type
