PDF Metadata Editor Free – View and Edit Title, Author, and Subject Tags

The PDF Metadata Editor allows users to inspect, update, and sanitize the internal document information dictionary (/Info) and XMP (Extensible Metadata Platform) XML streams embedded within PDF files. PDF documents automatically record identifying metadata during authoring, including computer user names, organization titles, author names, software build versions, creation timestamps, and camera details. In legal discovery, academic double-blind peer review, and corporate communications, publishing documents with outdated or revealing metadata creates confidentiality risks and professional embarrassment. This browser tool exposes all metadata properties in an editable interface, letting you update the document Title, Author, Subject, and Keywords, or completely scrub all identifying tags with a single click. Because processing occurs strictly client-side, your document bytes are rewritten in local memory without leaving your computer. Limitations to keep in mind are that cryptographically locked or certified PDF files will have their digital seal broken if internal metadata streams are rewritten.
