Not on standardized pages. Those pages are rebuilt from embedded page artwork, so review the stated limitations before conversion.

  • Standardized pages are rebuilt from embedded page artwork, so forms, links, annotations, accessibility tags, and signatures are not preserved on changed pages.
  • Cover mode can crop artwork at the page edge.
  • This is page-layout conversion, not redaction or document sanitization.
