Converting a document from PDF to Markdown format

Markdown version of this page, suitable for AI agents and automation

Converting PDF to Markdown helps you move static document content into editable, text-based workflows.

Use this workflow when you need to:

  • Extract content from PDFs into Markdown files
  • Reuse document text in documentation repositories
  • Integrate converted content into automation pipelines

Prepare the project

Register the SDK license before running conversion operations. For setup details, refer to the getting started with .NET SDK guide.

using GdPicture14;


LicenseManager licence = new LicenseManager();
licence.RegisterKEY(""); // Set your license key

Load the PDF document

Create a converter instance and load the source PDF:

using GdPictureDocumentConverter converter = new GdPictureDocumentConverter();
converter.LoadFromFile(@"input.pdf");

Convert to Markdown

Save the loaded content as Markdown:

converter.SaveAsMarkDown(@"output.md");

Verify the conversion output

After conversion, confirm that output.md exists and contains the expected content for your downstream workflow.

Output encoding and Unicode handling

The Markdown exporter writes UTF-8 Markdown without a byte order mark (BOM). This keeps the output compatible with tools that treat a BOM as content.

The exporter also handles stray Unicode surrogate characters in source content gracefully. These malformed characters don’t stop PDF-to-Markdown conversion, so the rest of the document remains available to downstream processing.

Conclusion

This guide converts a PDF document into Markdown so you can process and edit the content in text-first systems.
