@abhishek.sonkar Regarding reading headers/footers, this is an expected behavior. Headers/footers are exported as artifacts and Acrobat reader skips reading artifacts. You can configure this using Preferences->Reading->Reading Order->Override the reading order in tagged document.

Regarding reading whitespaces. If possible, could you please share the vide of the problem. We will check the issue and provide you more information.

  1. Please see the screenshot:

  2. The behavior is expected. They are empty paragraph in the source document:

    1357×805 78.2 KB

To avoid this, it is required to remove them either in the source document or by postprocessing output PDF document.

@abhishek.sonkar You are viewing in Tags tab. I view in Content tab, where artifacts are shown:

@alexey.noskov tags tab only decides if A11y reader will read those things or not.
could you share the video if you can reader header and footer with A11y tools

@abhishek.sonkar Headers/footers are exported as artifacts and Acrobat reader skips reading artifacts. Aspose.Words exports headers/footers the same way as MS Word does:
