Accessibility shipped. Your exported PDFs are now tagged, a real structure tree with headings, lists, links, and table header cells with proper scope, plus alt text on images. In plain terms: screen readers can actually read them in order, and the files pass veraPDF’s PDF/UA-1 checks.
The same export can also be PDF/A-3a for archival, so you don’t have to choose between “accessible” and “long-term”.
One honest caveat: we can give you a structurally valid, tagged document, but real conformance still needs a human call, meaningful alt text, sensible reading order, headings that actually describe sections. The tooling does the mechanical part; you bring the judgment.
If you’re exporting for a compliance requirement and something looks off in the tag tree, post the doc in Help and we’ll go through it.
