Ever noticed a PDF shows the wrong author name, or no title at all when you open it in your browser tab? That's controlled by the file's metadata — hidden details separate from the page content. You can edit PDF metadata for free, right in your browser, in seconds.

What Is PDF Metadata?

Metadata is information about a PDF that isn't part of the visible page content. It typically includes:

  • Title — often shown in browser tabs and some PDF viewers
  • Author — who created the document
  • Subject — a short description of what it's about
  • Keywords — searchable terms attached to the file
  • Creator / Producer — the software used to make the PDF

Tips for Best Results

💡 Pro Tip

Separate multiple keywords with commas — most PDF viewers and search tools treat them as individual searchable terms.

Editing Metadata Doesn't Change Your Content

Metadata is completely separate from the visible pages — updating it will never alter any text, images, or layout in your document.

Removing Personal Information

If you're sharing a document publicly, clearing the Author field can help strip out personal information before it goes out.

No. Metadata is separate from the visible page content — editing it does not change any text, images or layout in your PDF.
