Once you have completed the task of making your PDF document accessible, run a check on the PDF/Universal Accessibility (PDF/UA) compliance using any PDF compliance validator. If your PDF document passed the check and it meets all necessary accessibility criteria, you can mark it as PDF/UA compliant.
To mark a document as PDF/UA compliant
Open your PDF document with Nitro PDF Pro
Select File > Document Properties > Accessibility
Select the Mark the document as PDF/UA compliant checkbox
Click OK
Click Save on the top bar or press Ctrl+S on your keyboard to save your changes
