Why sponsor this project?

PDF table extraction is easy to underestimate and hard to make reliable in production.

ExtractPDF4J is designed for real-world document workflows, including:

  • bank statements
  • invoices
  • reports
  • scanned PDFs
  • mixed-layout business documents

Sponsorship helps keep the project actively maintained and growing.


What your support helps fund

Your sponsorship can help with:

  • maintaining the core library
  • adding new extraction capabilities
  • improving OCR support
  • expanding tests across more PDF formats
  • building better docs, demos, and examples
  • long-term open-source sustainability

Even if you are not able to sponsor financially, you can still support ExtractPDF4J by:

  • starring the repository
  • forking and contributing
  • opening issues
  • sharing the project with others
