Callas software ( has released pdfGoHTML, a free Adobe Acrobat plug-in for converting tagged PDF files into HTML supporting the ISO PDF/UA standard for universally accessible PDF documents and forms.

One click on the plug-in button converts the tagged PDF into HTML that’s opened in the default browser. In the resulting HTML different views can be selected to examine the tagging structure.

Callas pdfGoHTML works in Acrobat 9, 10 and 11 on both Mac and Windows. It can be downloaded at the Callas Software web site and tried out with the attached tagged PDF files.
