PDF Metadata Viewer reads the document information dictionary of any PDF file using pdfjs-dist and displays all available metadata fields: title, author, subject, creator, producer, PDF version, creation date, modification date, page count, and file size. Read-only — no modifications are made.
PDF creators aren't required to fill in all metadata fields. Many PDFs produced by automated systems or simple export tools omit author, title, and subject entirely.
No. The tool uses pdfjs-dist running entirely in your browser tab — the file is never transmitted to any server.
Title, author, subject, creator, producer, PDF version, creation date, modification date, page count, and file size, when present in the document.
Creator is typically the application that originally created the document (e.g. a word processor), while Producer is the tool that generated the PDF file itself (e.g. a PDF library or printer driver).
No, this tool is read-only. To edit metadata such as title or author, use a PDF editing tool that supports modifying the document information dictionary.
To verify authorship and creation tools, check when a document was last modified, confirm the page count before printing, or investigate the origin of an unfamiliar PDF.
Yes — scanned PDFs still have a document information dictionary (often filled in by scanning software), which this tool reads the same way as any other PDF.
