How to Edit PDF Metadata (Title, Author, Date) for Free

Every PDF file carries invisible information embedded in its metadata - the document title, author name, creation software, creation and modification dates, and more. This information is visible to anyone who checks the file properties, and sometimes it needs updating or cleaning up before sharing.

What Is PDF Metadata?

PDF metadata is a collection of structured information embedded in the file that describes the document. It's separate from the visible content - you won't see it on any page - but it's accessible to PDF viewers, search engines, and document management systems.

Standard PDF metadata fields include:

• Title - The document's title (often wrong or empty in PDFs exported from Word)
• Author - The person or organisation who created the document
• Subject - A short description of what the document is about
• Keywords - Tags for search and categorisation
• Creator - The application that originally created the content (e.g. Microsoft Word, Google Docs)
• Producer - The software that generated the PDF (e.g. Adobe PDF Writer)
• Creation Date - When the PDF was first created
• Modification Date - When it was last changed

Why Edit PDF Metadata?

Common reasons to update or clean up PDF metadata:

• Wrong title - PDFs exported from Word often use the filename or first heading as the title, which may not be appropriate
• Internal author name - The author field might reveal an employee's name or internal username that shouldn't be on a public document
• Software fingerprinting - The Creator field often reveals what software was used (competitors reading a pitch deck might notice)
• Date accuracy - If a document was recreated from an older version, the creation date may be wrong
• SEO for PDFs - Title and keywords in PDF metadata are indexed by Google; a well-set title improves discoverability
• Document management - Clean metadata makes PDFs easier to find and organise in document management systems

How to Check a PDF's Current Metadata

Before editing, you might want to see what metadata a PDF currently has:

• On Windows: Right-click the PDF → Properties → Details tab
• On Mac: Open in Preview → Tools → Show Inspector → General (ⓘ) tab
• In Adobe Reader: File → Properties → Description tab
• Online: Upload to PDF Metadata Editor - it loads the current values automatically

PDF Metadata and Privacy

PDF metadata can contain more personal information than you'd expect. A document created in Microsoft Word and then saved as PDF often carries the Windows username of the person who saved it, sometimes the organisation name registered with the software license, and occasionally even revision history or comments.

Before sharing a PDF publicly or sending to external parties, it's worth checking what the metadata contains. The PDF Metadata Editor makes this easy - upload the file, see what's there, and clear or update anything that shouldn't be shared.

After Editing Metadata: Further Steps

• Protect PDF - Add a password before distributing
• Add Watermark - Stamp the document before sharing
• Compress PDF - Reduce file size if the document is large

• Use PDF Metadata Editor to view current values and update any field for free.
• Clean metadata matters for privacy, SEO, and professional document presentation.
• Always check metadata before sharing PDFs publicly - it may contain internal information.
