  Markdown is widely used for writing technical documentation, project notes, README files, and online content. Its lightweight syntax makes documents easy to create, update, and manage. However, Markdown is not always the best format for sharing. When a document needs to be printed, archived, or distributed to users who do not use Markdown tools, PDF is usually a better choice because it provides a fixed layout and consistent appearance. In Java applications, automating Markdown-to-PDF conversion can be useful for documentation platforms, report generation systems, and publishing workflows.
