PDF Metadata Editor: View and Edit Document Properties

PDF metadata (also called document properties) is the hidden information embedded within a PDF file that describes the document without being visible on its pages. Standard metadata fields include Title, Author, Subject, Keywords, Creation Date, Modification Date, Producer (the software that created the PDF), and Creator (the application that generated the content). Additional metadata can include custom fields, XMP (Extensible Metadata Platform) data, and document statistics like page count and file size. Metadata serves important purposes: it helps search engines index web-published PDFs, enables document management systems to organize and categorize files, and provides attribution and version tracking. However, metadata can also contain sensitive information — the original author's name, the computer used to create the document, editing history, and software version information — that users may want to remove before sharing. Editing PDF metadata requires tools that can access and modify the document's internal property structures. While dedicated metadata editors exist (like ExifTool for cross-format metadata and PDF-specific tools), comprehensive PDF editors like pdfeditor.website provide metadata viewing and editing alongside content editing capabilities. This is particularly useful when you need to both update a document's content and its metadata in a single workflow — for example, correcting a report's text and updating its author and modification date simultaneously.
