About PDF Metadata Editor

View and edit PDF metadata including title, author, subject, and keywords using our free PDF metadata editor. Update document properties without changing page content, images, or formatting.

What is PDF Metadata?

PDF metadata is descriptive information stored inside a PDF document but not displayed on any page. It includes properties like the document title, author name, subject, keywords, creator application, and modification date. Metadata improves searchability and document management.

Features

  • Read and edit title, author, subject, and keywords
  • Update creator application field
  • View page count, file size, producer, and PDF version
  • Automatically updates the modification date on save
  • Browser-based processing with no file uploads
  • No software installation required
  • Supports any valid PDF file

Privacy Focused Processing

Metadata editing happens entirely in your browser using pdf-lib. Your PDF is never uploaded to any external server, keeping document contents and properties private.

Common Use Cases

  • Add title and author information to PDFs
  • Tag documents with keywords for better searchability
  • Clean up or correct incorrect metadata before sharing
  • Remove creator software information from exported PDFs
  • Verify and update document properties before archiving

Why Use This PDF Metadata Editor?

Update PDF document properties quickly and privately without needing Adobe Acrobat or uploading your files anywhere.

Frequently Asked Questions

Yes. Simply clear any field you want to remove and save the file. Fields left empty will be absent or blank in the downloaded PDF, effectively removing that metadata property.
