    "input.pdf",
    "Output/PDFConversions/output.md",
    "--pages", "1-10"
], capture_output=True, text=True)

print(result.stdout)

Markdown formatting: Preserves headers, lists, and structure
Image extraction: Saves images to
```
images/
```
subfolder automatically
Page selection: Extract specific pages or ranges
Scanned PDF support: True OCR capability for image-based PDFs
Relative paths: Image references use
```
![...](images/img-X.jpeg)
```

Requirements

The script requires:

Mistral API key in
```
Notes/.env
```
(line 2:
```
mistral_api_key=...
```
)
Python packages:
```
mistralai
```
,
```
python-dotenv
```
,
```
pypdf
```

Common Use Cases

Convert Research Paper

bash

python scripts/convert_pdf_to_markdown.py \
  "Data/papers/research.pdf" \
  "Notes/Paper Markdown/research.md"

Extract Specific Sections

bash

# Extract pages 10-20 (introduction and methods)
python scripts/convert_pdf_to_markdown.py \
  "paper.pdf" \
  "Notes/Paper Markdown/intro_methods.md" \
  --pages "10-20"

Extract Figures Only

bash

# Extract pages with figures
python scripts/convert_pdf_to_markdown.py \
  "paper.pdf" \
  "Notes/Paper Markdown/figures.md" \
  --pages "25,27,30,35"

Error Handling

API Key Not Found:

Error: Mistral API key not found in Notes/.env

→ Add

mistral_api_key=YOUR_KEY

to line 2 of

Notes/.env

Page Out of Range:

Warning: Page 100 out of range, skipping

→ Check PDF page count and adjust page selection

API Rate Limit: → Wait a moment and retry, or reduce page count per request

Notes

Images are saved as JPEG files in
```
images/
```
subfolder
Markdown image references are automatically updated to
```
images/img-X.jpeg
```
Large PDFs may take longer to process due to API limits
For simple text extraction without OCR, consider using the
```
pdf
```
skill instead
Scanned PDFs benefit most from this skill's OCR capability
