PDF to Markdown Converter

Workflow

1. Ask for the PDF path if the user hasn't provided one.
2. Ask for the output directory — suggest ./output or the same folder as the PDF if the user doesn't have a preference.
3. Check dependencies — the script needs PyMuPDF and Pillow. If they're missing, install them:

   pip install pymupdf pillow
   

4. Run the script and show the live output to the user.
5. Parse the JSON summary printed at the end (last line of stdout) to report:
   • How many pages were processed
   • How many images were extracted
   • The path to the generated .md file
6. Show a quick preview — read the first ~50 lines of the generated Markdown and display them to the user so they can see what was produced.

Output structure

<output_dir>/
├── <pdf-name>.md          ← the Markdown file
└── <pdf-name>_images/     ← extracted images referenced in the .md
    ├── image_1.png
    ├── image_2.jpg
    └── vector_page_3.png  ← rendered pages with vector diagrams

Handling errors

• File not found: Confirm the path with the user and try again.
• Import error (fitz / PIL): Run pip install pymupdf pillow first.
• No images extracted: This is fine — the Markdown will still contain all text. Let the user know.
• Permission error on output dir: Suggest a different output path.

Example interaction

User: "Can you convert my thesis.pdf to Markdown?"

1. Ask: "What's the path to thesis.pdf? And where should I save the output?"
2. Run the script.
3. Report: "Done! 42 pages processed, 7 images extracted. Markdown saved to ./output/thesis.md."
4. Show the first 50 lines of the .md as a preview.
