As answered by people managing CodeBeautify and OctoPDF.
OctoPDF's answer:
OctoPDF - free online PDF verification provides a combination of accuracy, transparency, and simplicity. Built on industry-leading PDF technology from BFO, OctoPDF performs the same deep validation checks trusted by developers, enterprises, and government organizations worldwide. Unlike many online tools, it verifies not only PDF/A compliance but also PDF/UA accessibility, digital signatures, timestamps, and file structure against the Arlington Model — all without requiring installation or registration. The result is a fast, secure, and standards-compliant way to validate PDFs that you can use and share freely.
OctoPDF's answer:
OctoPDF isn’t just another online PDF checker — it’s built by BFO, a company that’s been developing professional-grade PDF software since 1999. We’re active members of the ISO working groups for PDF/A and PDF/UA, and were the first to release a PDF/UA-2 validator. That same deep technical knowledge powers OctoPDF. Unlike many tools that give vague “pass/fail” results, OctoPDF provides a detailed breakdown of accessibility, archival compliance, security, and structure, tested against the Arlington Model. It’s accurate, transparent, and entirely free to use — the same technology trusted by developers, enterprises, and government agencies worldwide.
OctoPDF's answer:
OctoPDF is designed for anyone who needs to ensure their PDF documents meet professional, legal, or archival standards. Our primary audience includes government departments, legal firms, financial institutions, and enterprises that rely on PDF/A for long-term storage and compliance, or PDF/UA for accessibility and public communication. It’s also used by developers, digital archivists, and records managers who need to validate documents at scale or verify the integrity of signed and timestamped PDFs. Whether for e-invoicing, policy documents, contracts, or archival preservation, OctoPDF provides fast, reliable validation that meets industry and regulatory expectations.
OctoPDF's answer:
OctoPDF is built by BFO (Big Faceless Organization), pioneers in PDF software development since 1999. Our audience includes government agencies, legal professionals, financial institutions, and enterprises that depend on precise, standards-compliant PDF documents. These organizations use OctoPDF to verify PDF/A for archival storage, PDF/UA for accessibility, and digital signatures for authenticity. Developers and records managers also rely on it to validate PDFs for e-invoicing, contracts, policy documents, and long-term preservation. This is just an application we built with our PDF Library. If you want to do verification at scale, convert PDF to PDF/A or bitmap, convert HTML to PDF, sign PDFs, and more, we have rock-solid tools for that. Powered by decades of expertise and active participation in ISO working groups for PDF standards, OctoPDF brings professional-grade validation to everyone — free, fast, and trusted worldwide.
