Why You Need Low-Level PDF Expertise
Standard libraries (like iText or PDF.js) rely on documents being perfectly formed. In the real world, PDFs are often corrupt, malformed, or structured in ways that break standard extractors. My services focus on building custom solutions for these edge cases.
Recover & Repair Corrupt Files
Do you have critical documents that won't open? I build custom parsers that bypass the standard header/xref checks to salvage data from damaged streams and reconstruct valid files.
Precision Data Extraction
Stop relying on text-scraping that breaks when formatting changes. I implement geometric analysis algorithms to accurately extract tables, forms, and invoice data based on visual layout, not just stream order.
High-Performance Generation
Need to generate 100,000 documents an hour? I optimize the generation pipeline by writing directly to the output stream, bypassing heavy object graphs and memory overhead.
Consulting Services
- Audit & Optimization: Analyze your current document storage to reduce file size (stream compression, font subsetting) without losing quality.
- Compliance workflows: Ensure generated documents meet specific archival standards (PDF/A) or industry requirements.
- Custom Rendering Engines: Build specialized viewers or printers for proprietary outputs.
