Workflow

1. Identify format — Check file extension
2. Extract text — Use appropriate tool
3. Get metadata — Author, date, pages, etc.
4. Process content — Summarize, search, transform

Notes

• PDFs with scanned images need OCR (pdftoppm + tesseract)
• Encrypted PDFs require password
• Complex formatting may be lost in text extraction
• For tables in PDFs, consider tabula or camelot
