PDF to Markdown Converter

Overview

This skill converts PDF files to Markdown format using the PyMuPDF (fitz) library. It extracts text content and saves embedded images as separate PNG files. This is a fast and lightweight alternative to Docling.

Special Features:

  • ✅ Automatically fixes LaTeX-style umlauts (¨a, ¨o, ¨u → ä, ö, ü)
  • ✅ Converts ß to ss (Swiss German style)
  • ✅ Corrects common LaTeX encoding issues
  • ✅ Preserves text layout
  • ✅ Extracts all images as PNG files

Prerequisites

Ensure PyMuPDF is installed (installs in ~10-20 seconds):

pip install PyMuPDF --break-system-packages

Optional for better image format support:

pip install Pillow --break-system-packages

Usage Workflow

  1. Receive PDF file: User provides the PDF file path
  2. Validate input: Check that the file exists and is a valid PDF
  3. Run conversion: Execute pdf_converter.py with the PDF path
  4. Output organization:
    • Markdown file: <original_name>.md
    • Images folder: <original_name>_images/ containing PNG files
    • Images are referenced in the Markdown with relative paths

Conversion Command

python scripts/pdf_converter.py <input.pdf> [output_dir]

Parameters:

  • input.pdf: Path to the source PDF file
  • output_dir: (Optional) Output directory. Defaults to current directory

Output Structure

output_dir/
├── document.md              # Converted markdown content
└── document_images/         # Extracted images (if any)
    ├── image_001.png
    ├── image_002.png
    └── ...

Error Handling

If conversion fails:

  • Check PDF is not corrupted or password-protected
  • Verify Docling installation
  • Ensure sufficient disk space for image extraction
  • Review console output for specific error messages

Best Practices

  • Large PDFs may take time to process - inform user
  • Preview the first page for complex documents to verify quality
  • For batch processing, process files sequentially to avoid memory issues
  • Preserve original PDF files - never overwrite source documents
