What information does PDF metadata contain?
File size, page dimensions, page count, PDF version (1.4, 1.7, 2.0), encryption type, document title, author, subject, keywords, creator (original software) and producer (PDF converter), creation and modification dates.
Can metadata reveal who created a document?
Yes — the Author field often contains the real name of the person who created the document, and the Creator field shows which software was used. This information is invisible to most readers but easily accessible with this tool.
What is the PDF version number?
The PDF specification version (1.4, 1.7, 2.0) determines which features are supported. Most PDFs use version 1.4–1.7. PDF 2.0 (ISO 32000-2) is the latest standard.
