pdfGoHTML is a free Acrobat plug-in (Acrobat DC Standard and Pro only) converting tagged PDF files into HTML, supporting PDF/UA. It shows where the tagging structure of the PDF needs improvement.
It substantially speeds up the creation and evaluation of tagged PDFs and ensures a much higher degree of usability of tagged PDF files. When opening a PDF file, pdfGoHTML immediately indicates whether or not the file is tagged and allows a one-button conversion into HTML in the default browser. Users can easily switch how the HTML is displayed to adjust it to their specific needs: browser default, structure tags, easy reader, inverted, low vision, and dyslexia.

For those who need to evaluate the tagging quality of a PDF file, the ‘structure tags’ view in the exported HTML provides a very quick, intuitive quality analysis tool that shows where the tagging structure of a tagged PDF needs improvement. pdfGoHTML will substantially speed up the creation and evaluation of tagged PDFs and ensures a much higher degree of usability of tagged PDF files.
Tenable’s Nessus is the gold standard for vulnerability assessment. However, for professionals operating in air-gapped or highly restricted environments (SCADA, government, finance), the offline activation process is a necessity. While online activation is seamless, offline activation introduces a unique set of friction points.
The "License already in use" error typically occurs when Nessus detects that the license file has already been activated on another system or scanner. This error can be caused by: nessus offline activation license already in use
