Syntax
public class DocumentInfo : Object

A read-only record of the metadata embedded in a PDF file, DocumentInfo gives every field that PDF producers write into a document's information dictionary: authorship, timestamps, toolchain provenance, and descriptive text. Retrieving this object is the first step whenever a workflow needs to audit, display, or index PDF metadata without opening the full document for rendering.

DocumentInfo surfaces eight properties drawn directly from the PDF information dictionary. The string fields, Author, Creator, Keywords, Producer, Subject, and Title, mirror the standard PDF metadata keys by the same names. Creator records the application that originally created the source document (for example, a word processor), while Producer identifies the software that converted or wrote the PDF bytes. Keywords arrives as a single string whose internal delimiter follows whatever convention the producing tool used, so splitting on commas or semicolons is the caller's responsibility.

The two timestamp properties, CreationDate and ModDate, are typed as Nullable<DateTimeOffset> rather than plain strings. That choice reflects the PDF specification: a document may omit either date entirely, and when present the value carries timezone information. Checking for null before formatting is therefore correct practice, not defensive boilerplate.

All eight properties are read-only. DocumentInfo is a value-carrying record, not a builder, so there are no setters and no constructor to call directly. The object is obtained from the IronPDF conversion pipeline rather than constructed in application code.

using PdfToSvg;

using var doc = PdfDocument.Load("report.pdf");
DocumentInfo info = doc.Info;

Console.WriteLine($"Title:    {info.Title}");
Console.WriteLine($"Author:   {info.Author}");
Console.WriteLine($"Keywords: {info.Keywords}");

if (info.CreationDate.HasValue)
    Console.WriteLine($"Created:  {info.CreationDate.Value:yyyy-MM-dd}");

if (info.ModDate.HasValue)
    Console.WriteLine($"Modified: {info.ModDate.Value:yyyy-MM-dd}");

The IronPDF get-started guide covers initial setup. The PDF metadata how-to explains reading and writing document properties in depth. The PDF to SVG conversion example shows the broader pipeline that surfaces DocumentInfo. Full API documentation is available at the IronPDF docs hub.
