Technical Implementation
This application uses the PDF-Lib library to manipulate PDF files directly in the browser. The conversion process includes:
- Font Analysis: Extracts and embeds font information to ensure text remains renderable
- Color Space Conversion: Converts colors to device-independent color spaces
- Metadata Injection: Adds XMP metadata required by PDF/A standards
- Structure Preservation: Maintains document structure for accessibility
Note: For production use with large documents, consider implementing web workers for background processing to prevent UI blocking.
