The problem exists of converting PDF files to the longer-term readable and archive-suitable PDFA format. This is a challenge because the normal PDF format may not be able to ensure the readability of documents over a longer period. In addition, there are concerns about the security of the documents, as some converters could potentially compromise user privacy. Executing this conversion requires specialist knowledge and the right tools, making it a difficult problem to solve. Another point is that not all converters are available online and user-friendly, which makes the process even more complicated.

The PDF to PDFA converter tool provides an efficient and simple solution to the problem. It allows the conversion of regular PDF files into the long-term readable PDFA format. Not only does it guarantee the readability of the converted documents even after many years, but it also serves as a secure tool, as it automatically deletes all uploaded files after the conversion process, ensuring users' privacy. The tool is accessible online and designed to be user-friendly, so no special knowledge is required to use it. Therefore, it resolves the challenge of PDF to PDFA conversion in an understandable and accessible way.
