Convert PDF to PDF/A formats in Python

Aspose.PDF for Python allows you to convert a PDF file to a PDF/A compliant PDF file. Before doing so, the file must be validated. This topic explains how.

Please note we follow Adobe Preflight for validating PDF/A conformance. All tools on the market have their own “representation” of PDF/A conformance. Please check this article on PDF/A validation tools for reference. We chose Adobe products for verifying how Aspose.PDF produces PDF files because Adobe is at the center of everything connected to PDF.

Convert the file using the Document class Convert method. Before converting the PDF to PDF/A compliant file, validate the PDF using the Validate method. The validation result is stored in an XML file and then this result is also passed to the Convert method. You can also specify the action for the elements which cannot be converted using the ConvertErrorAction enumeration.
