PDF Craft breaks through the limitations of a single text conversion to achieve a multimodal Markdown output that includes mixed-text, table retention, and chapter structure. Its image processing module uses adaptive threshold segmentation technology to intelligently recognize the chart elements in the scanned document, maintain the original resolution screenshots and automatically generate Markdown embedded code. In practice, for professional books containing 200 technical illustrations, the system can maintain the accuracy of image references above 95% and automatically generate alt-text descriptions. Extended functionality supports the output of EPUB standard e-book format, through the pandoc transcoding engine to achieve font retention, table of contents generation and other publishing-level features, so that individual users can also produce digital documents to meet the standards of commercial e-books.
