How Do I Convert a Markdown String to PDF?
Use the RenderMarkdownStringAsPdf method to convert a string in Markdown format to a PDF document. All the features available in RenderingOptions, including the addition of text and HTML headers, footers, text overlays, image stamping, and page numbering, as well as setting custom page dimensions and orientations, can also be used with this rendering method. Once created, you can modify pages through actions like merging, splitting, and rotating, and you can also add annotations and bookmarks.
The Markdown to PDF conversion process in IronPDF uses the Chrome rendering engine, ensuring output that preserves formatting and styling. When working with Markdown strings, you can include standard Markdown syntax such as headings, bold and italic text, lists, and links. The renderer automatically interprets these elements and converts them into properly formatted PDF content.
using IronPdf;
// Instantiate Renderer
ChromePdfRenderer renderer = new ChromePdfRenderer();
// Markdown string
string md = "This is some **bold** and *italic* text.";
// Render from markdown string
PdfDocument pdf = renderer.RenderMarkdownStringAsPdf(md);
// Save the PDF
pdf.SaveAs("pdfFromMarkdownString.pdf");Imports IronPdf
' Instantiate Renderer
Private renderer As New ChromePdfRenderer()
' Markdown string
Private md As String = "This is some **bold** and *italic* text."
' Render from markdown string
Private pdf As PdfDocument = renderer.RenderMarkdownStringAsPdf(md)
' Save the PDF
pdf.SaveAs("pdfFromMarkdownString.pdf")For more advanced scenarios, you might want to customize the PDF output using rendering options. These options allow you to set margins, paper size, orientation, and even apply custom CSS styling to enhance the appearance of your PDF documents. Additionally, you can incorporate watermarks or backgrounds to create branded documents.
How Do I Convert a Markdown File to PDF?
Use the RenderMarkdownFileAsPdf method to convert a Markdown file into a PDF document. You can download a sample Markdown file for conversion. Let's convert this sample file into a PDF.
The file-based conversion approach is particularly useful when working with existing documentation, README files, or any Markdown content stored in your project. IronPDF handles the file reading and conversion process, making it suitable for batch processing multiple Markdown files or integrating into documentation generation workflows.
What Code Do I Need to Convert a Markdown File?
using IronPdf;
// Instantiate Renderer
ChromePdfRenderer renderer = new ChromePdfRenderer();
// Render from markdown file
PdfDocument pdf = renderer.RenderMarkdownFileAsPdf("sample.md");
// Save the PDF
pdf.SaveAs("pdfFromMarkdownFile.pdf");Imports IronPdf
' Instantiate Renderer
Private renderer As New ChromePdfRenderer()
' Render from markdown file
Private pdf As PdfDocument = renderer.RenderMarkdownFileAsPdf("sample.md")
' Save the PDF
pdf.SaveAs("pdfFromMarkdownFile.pdf")For production applications, you may want to implement error handling and consider using async methods for better performance, especially when converting multiple files. The conversion process supports relative and absolute file paths, making it flexible for different deployment scenarios including Azure or AWS environments.
What Does the Final PDF Look Like?
As you can see from the resulting PDF document, some Markdown functionalities like Code, Code Block, Blockquote, Tables, and Checkbox are not working. This is a current limitation of the method.
