About Edit Metadata

Modufile's PDF Metadata Editor lets you view and modify the metadata fields stored in a PDF's Info dictionary — including Title, Author, Subject, Keywords, Creator, and Producer. This is useful for removing personal information before sharing a document, adding a descriptive title for accessibility compliance, or updating keywords for document management systems. The tool uses pdf-lib to read and write metadata without touching page content, and runs entirely in your browser with no uploads.
