Browser-Based Technical Limitations Analysis
1. File Processing Constraints
Universal browser limitations:
- 10MB typical upload limits - enterprise documents excluded
- 300 page maximums - technical manuals rejected
- Browser memory limits - complex PDFs crash processing
- Network dependency - offline processing impossible
Server-Side Processing Issues
External processing concerns:
- Document exposure to third-party servers
- Data privacy compromised for sensitive content
- Processing queue delays during peak usage
- Server reliability affects document availability
2. OCR Quality Degradation
Browser OCR limitations:
