Why is pdfRest the best API to convert PDF to PDF/A?

pdfRest offers the best solution for converting PDF documents to PDF/A specifications, because it supports top PDF/A conformance, robust versions, and problemetic input files.

Top PDF/A Conformance

Extensive research and comparative testing have demonstrated that pdfRest’s technology generates PDF/A documents with the highest success rate among leading PDF technology solutions.

pdfRest’s conversion technology produced perfect conformance to the ISO 19005-2 specifications over 95% of the time, compared to an average of 84% for leading competitors.

Robust Version/Level Support

pdfRest’s Convert to PDF/A supports a wide range of PDF/A conformance versions and levels, including:

  • PDF/A-1b
  • PDF/A-2b
  • PDF/A-2u

Convert Problem Files

Occasionally a PDF will contain a mix of conditions that make it incompatible with conversion to PDF/A. Most tools will return an error in this situation, but pdfRest offers a fallback plan you can turn on that will rasterize any problematic pages in the document to ensure the file converts successfully and conforms to PDF/A standards.
