What is PDF Metadata
In the context of PDFs, metadata refers to the additional information that is embedded within a PDF file.
PDF files have two types of metadata.
The first is called the Document Information Dictionary, which includes details like the author's name, title of the document, creation and update dates. It's optional and can be added to the file.
The second type is Metadata Streams, introduced in PDF 1.4, which use a standard called Extensible Metadata Platform (XMP) to include additional information in XML format. This can include details about images, fonts, and the entire document itself.
Metadata helps in organizing and categorizing PDF files, making it easier to search for specific documents. It also enables better management and retrieval of information, especially in large collections of PDF files.
It is possible to add or edit metadata using PDF editing software or specific tools designed for managing PDF metadata. By leveraging metadata, users can improve document organization, enhance searchability, and streamline document workflows.
Given the frequency of PDFs in search results, ensuring that your PDF documents have relevant metadata can significantly enhance their visibility and click-through rates.
