PDF Metadata Editor is a free online tool that lets you view and edit document properties like title, author, subject, and keywords. WayPDF edits metadata entirely in your browser using pdf-lib — your document content remains unchanged and never leaves your device.

Common use cases include adding author names to academic papers, updating publication titles for library submissions, inserting subject categories for document management, adding searchable keywords for asset libraries, and cleaning metadata from confidential documents before external sharing.

Browser-based editing ensures your document properties are modified on your own device. The actual PDF content and pages remain completely untouched, and no data is ever transmitted over the network.
