What Is PDF Metadata Editor?

A free online PDF metadata editor that lets you view and modify document metadata including title, author, subject, keywords, producer, and creator. Also shows file-level info like page count and file size. Preview metadata changes and apply them to your PDF. All processing is local.

Every PDF contains metadata — hidden information about the document that includes the title, author, subject, keywords, producer application, and creator tool. This metadata is useful for organizing document libraries, improving searchability, and providing context. But it can also expose information you may not want to share, such as the author's name or the software used to create the document.

PDF Metadata Editor lets you view all metadata fields in any PDF and edit the ones that are writable: title, author, subject, and keywords. The producer and creator fields are read-only as they are set by the software that generated the PDF. You can update individual fields, or click "Clear All" to reset all editable fields to empty values.

The tool displays the current metadata alongside the file information (page count and file size). Edit any field by typing a new value. A preview section shows the metadata as it will appear after saving, so you can verify your changes before applying them.

All processing is local using PDF-Lib. Your PDF never leaves your browser. This is important when editing metadata on confidential documents where you do not want the file transmitted to a server. After saving, download the updated PDF with your metadata changes applied.

Real-World Use Cases for PDF Metadata Editor

Adding Author and Title Information for Document Organization

A team member downloads a PDF report but it shows "Unknown Author" and "Untitled" in the document properties. They upload the PDF, enter the correct title and author, add relevant keywords, and save. The updated PDF now displays properly in document management systems and search results.

Removing Personal Metadata Before Sharing

Before sharing a PDF publicly, a user checks the metadata and finds it contains their full name as the author and the company software name as the creator. They clear the author field and remove identifying keywords, then save a clean version for external distribution.

Standardizing Keywords Across a Document Library

A content manager is organizing a library of 50 training PDFs. They open each PDF in the metadata editor and add standardized keywords like "training," "onboarding," and the department name. This makes the documents searchable by keyword in the document management system.

Pro Tips for PDF Metadata Editor

  • 1Clear the author field before publicly sharing PDFs created on your personal computer. The author field often defaults to your operating system username or software license name, which may be personally identifiable.
  • 2Use the keywords field to add tags that improve document searchability. Keywords are indexed by document management systems, PDF readers, and search tools like Windows Search and Spotlight.
  • 3The producer and creator fields reveal which software generated the PDF (e.g., "Microsoft Word" or "Adobe Acrobat"). If you want to hide this information, you cannot edit these fields directly — instead, re-save the PDF through a different tool.
  • 4Before editing, note the original metadata in case you need to restore it. The tool does not have an undo feature, so consider keeping a copy of the original PDF until you verify the updated version is correct.
