Created attachment 201330 [details] Simple example file from Writer In recent master, when I export a simple file as PDF-2 compatible and PDF/UA enabled, the PAC tool does not open it because it does not find the PDF header. This makes it impossible to see what is the accessibility situation in certain files. 1. Open attached example 2. Export it as PDF, selecting the PDF version 2.0 in the PDF Export settings dialog. Selecting 1.7 works. Selecting UA or Hybrid is not necessary. 3. Open the resulting PDF in the PAC 2024 tool -> Error message.

In PAC release notes I see: "PDF 2.0 is now supported to a limited extent. PAC currently fully supports documents up to and including PDF standard 1.7. Documents based on newer standards are processed according to a "best try" approach. It is possible that errors or unreliable results may occur." Also doesn't seem like it supports PDF/UA-2, which is probably why it complains? I tested the PDF/A-4 and PDF 2-0 compliance with VeraPDF and that passes, but PDF/UA-2 still needs some work.
It complains also when the PDF/UA option if off. OTOH, it may be not our bug, thanks for checking the release notes! Let's wait until they release something that they claim supports PDF 2 and recheck then.
