libmumd 0.1.0

Convert documents (Office, PDF) to Markdown — optimized for Persian/Farsi and multilingual content

libmumd

Convert documents to clean, LLM-ready Markdown.

---

Why libmumd?

Most document converters produce messy output — broken tables, lost formatting, garbled non-English text. libmumd is different:

• Persian & Arabic first-class support — Correctly handles RTL text, Persian typography, and Arabic script
• Better than markitdown alone — Uses PyMuPDF's layout engine for cleaner, more accurate conversion
• Multi-language support — Handles Persian, Arabic, Chinese, Japanese, Korean, and European languages
• Table detection — Automatically converts complex tables to Markdown format
• Figure & image handling — Extracts and references images properly
• Layout-aware — Preserves reading order, headers, and document structure
• No GPU required — Runs on any machine with Python

Persian (Farsi) & Arabic Support

libmumd is built with Persian and Arabic documents in mind:

• RTL text handling — Correctly processes right-to-left text
• Persian typography — Preserves proper character connections and diacritics
• Mixed content — Handles documents with both Persian/Arabic and English text
• PDF extraction — Extracts Persian text without garbling or losing characters
• Font support — Works with Persian fonts like IRANSans, Vazirmatn, and more

from libmumd import convert_file

# Convert a Persian PDF document
result = convert_file("persian-document.pdf")
# Output preserves RTL text and Persian characters correctly
