Hello!
Recently, we faced the problem of converting pdf files to pdf/A. We tried to convert through Aspose, and the file is formed incorrectly (the text was different from the original). Through the pdf24 creator 8.8.2 the file was formed correctly. I can not find on your site information about the methods and algorithms for converting your software. Do you have a description of your conversion to PDF algorithm? If not, could you quote it? Or maybe you have an API description to use for our objective.
Example:

The PDF24 Creator uses Ghostscript under the hood to create PDF/A files.
