Markdown and PDF Conversion

Starting in 12.0, Foxit PDF SDK supports bidirectional conversion between Markdown and PDF: Md2PDF::ConvertFromMarkdown (Markdown → PDF) and PDF2Md::ConvertToMarkdown (PDF → Markdown). Before use, load the Foxit PDF Conversion SDK dynamic library and ensure you have the corresponding module license.

For complete runnable samples, see examples/simple_demo/md2pdf and examples/simple_demo/pdf2md in the product package. See the API Reference for class and method details.

System requirements

• Platforms: Windows, Linux (Mac / Android headers are not currently exposed)
• Languages: C, C++, Java, C#, Python, Node.js, Go
• License: Markdown → PDF requires the Md2PDF module; PDF → Markdown requires the PDF2Md module
• Dependencies: Foxit PDF Conversion SDK dynamic library (for example, fpdfconversionsdk_win64.dll on Windows, libfpdfconversionsdk.so on Linux)

Markdown to PDF

Typical flow: Library::Initialize → Md2PDF::Initialize(library_path) → configure Md2PDFSettingData → ConvertFromMarkdown → Md2PDF::Release.

Common Md2PDFSettingData fields include page width/height, margins, body font size (base_font_size), custom font path, style JSON path, and whether to embed fonts. When unset, defaults apply (approximately Letter paper size, 72 pt margins, and so on).

c++

using namespace foxit::addon::conversion::md2pdf;

// Assume Library::Initialize has already been called; library_path points to the Conversion SDK dynamic library.
Md2PDF::Initialize(library_path);

Md2PDFSettingData setting_data;
bool ok = Md2PDF::ConvertFromMarkdown(src_md_path, L"", saved_pdf_path, setting_data);

PDF to Markdown

Typical flow: Library::Initialize → PDF2Md::Initialize(library_path) → configure PDF2MdSettingData → ConvertToMarkdown → PDF2Md::Release.

ConvertToMarkdown can specify an image export subdirectory name (directory name only, without path separators). When empty, the default is <md_basename>_images next to the output Markdown file.

Common PDF2MdSettingData fields:

• table_format: export tables as Markdown pipe tables (e_TableFormatMarkdown) or HTML tables (e_TableFormatHTML)
• include_header_footer: whether to include headers and footers
• enable_italic / enable_bold: whether to preserve italic / bold markup
• skip_ocr_pages: whether to skip scanned pages that contain only paths/images (when false, such pages may raise errors)
