Best Practices

DO (Recommended)

1. Validation

   • Always validate PDF files before processing
   • Check for encryption and permissions
   • Verify file integrity

2. Error Handling

   • Handle corrupted PDFs gracefully
   • Provide meaningful error messages
   • Log processing steps

3. Performance

   • Process pages in batches for large PDFs
   • Use multiprocessing when possible
   • Cache extracted data

DON'T (Avoid)

1. Security Issues

   • ❌ Process PDFs from untrusted sources without validation
   • ❌ Execute embedded scripts in PDFs
   • ❌ Ignore encryption warnings

2. Performance Issues

   • ❌ Load entire PDF into memory unnecessarily
   • ❌ Process pages sequentially when parallel is possible
   • ❌ Ignore memory limits

3. Quality Issues

   • ❌ Skip OCR for scanned documents
   • ❌ Ignore layout and formatting
   • ❌ Assume all PDFs have the same structure
