Edit PDF Metadata

What is Edit PDF Metadata?

Edit PDF Metadata is a free online tool that lets you view and modify the document properties of your PDF, including the title, author, subject, keywords, creator, and producer fields. These hidden properties influence how your document appears in search results, file managers, and document management systems. Correcting them ensures your PDF is properly attributed and easy to find. The tool is powered by the pdf-lib JavaScript library and runs entirely within your browser. Your file is never uploaded to any server, so confidential documents with sensitive authorship or organizational information stay fully private.

When to Use Edit PDF Metadata

Use this tool whenever you need to update or correct the hidden properties of a PDF document. Common scenarios include:

• Setting a descriptive title and author before publishing a PDF on your website.
• Removing sensitive metadata (such as an internal author name) before sharing externally.
• Adding keywords so the document is easier to find in your organization's search system.
• Correcting the subject line for proper categorization in a document management platform.
• Updating the creator field after converting a document from another format into PDF.

How It Works

Upload your PDF by dragging it into the drop zone or using the file picker. The tool reads the existing metadata and displays each field in an editable form. Update the title, author, subject, keywords, or any other property as needed. Click save, and pdf-lib writes the new metadata into the document within your browser, then generates an updated PDF for download. The entire process is client-side, so it works offline once loaded, requires no account, adds no watermark, and is completely free.
