What is PDF Metadata?
PDF metadata is the information stored inside a PDF file that describes the document — such as title, author, subject, and keywords. This metadata helps with document organization, search engine indexing, and accessibility. Some metadata fields like Producer and Creator are automatically set by the software used to create the PDF.
This tool runs entirely in your browser using the pdf-lib library. Your files never leave your device.
