Built on a proven Microsoft foundation, free to use and extend.
Capabilities
What the platform doesEverything becomes plain text you can govern.
Word documents with formatting, spreadsheets as tables, slide decks with speaker notes, scanned images through OCR, e-books, structured data files, even zipped archives: MarkForge extracts them all into clean, consistent Markdown that version control and AI pipelines can actually use.
- Full Office suite support
- OCR-powered image extraction
- Archives processed in one pass
From plain text to a document you would hand a client.
Choose a page size from A5 to A3, add custom headers and footers, and MarkForge renders syntax-highlighted code blocks and professionally styled tables into a PDF that looks engineered rather than exported.
Write plainly. Publish professionally.
