Output Formats

MuPDF.NET can produce output in four formats depending on your use case:
FormatFunctionBest For
MarkdownToMarkdown()LLM ingestion, RAG pipelines, readable docs
JSONToJson()Custom pipelines needing bounding boxes and layout data
Plain TextToText()Simple text extraction, search indexing
ImagesToMarkdown(writeImages: true)Preserving figures, charts, and diagrams

​
Markdown

The default and most commonly used output format. Text is extracted in reading order with headings, lists, tables, and inline formatting preserved where detectable. 
string mdText = PdfExtractor.ToMarkdown("document.pdf");

​
JSON

Returns structured data including bounding boxes, font information, and layout metadata for every block on the page. Useful for building custom post-processing pipelines. 
string json_output = PdfExtractor.ToJson("document.pdf");

​
Plain Text

Strips all formatting and returns raw text content. Ideal when downstream tools do not need Markdown syntax. 
string text = PdfExtractor.ToText("document.pdf");

​
Images

When writeImages: true is passed to ToMarkdown(), embedded images and graphics are extracted and saved to disk. Image paths are referenced inline in the Markdown output. 
string mdText = PdfExtractor.ToMarkdown("document.pdf", writeImages: true, imagePath: "images/");
