callas software has released pdfGoHTML, a free Adobe Acrobat plug-in converting tagged PDF files into HTML supporting the ISO PDF/UA standard for universally accessible PDF documents and forms. One simple click on the plug-in button converts the tagged PDF into HTML that is opened in the default browser. In the resulting HTML different views can be selected to examine the tagging structure, have an easier reading experience or make the document more easily readable for people with visual disabilities or dyslexia.
callas software, known for its quality control and document archival software, worked closely with its sister company axaio software when focusing its attention on tagged PDF. Last year, axaio software released the beta version of its MadeToTag product, an Adobe InDesign plug-in to streamline tagging of Adobe InDesign files and create tagged PDF files. Tagged PDF files are essential for screen reader devices helping visually impaired people or reading software for people with learning disabilities such as dyslexia. In addition, tagged PDF files enable substantially better indexing by search engines and a more reliable text extraction or conversion to other formats.
It is this last property of tagged PDFs that is used by pdfGoHTML to allow high quality conversion of tagged PDFs into HTML. 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. callas pdfGoHTML will substantially speed up the creation and evaluation of tagged PDFs, and ensures a much higher degree of usability of tagged PDF files.
callas pdfGoHTML is immediately available as a free tool. It works in Acrobat 9, 10 and 11 on both Mac and Windows. It can be downloaded here and tried out with the attached tagged PDF files. This short video explains why pdfGoHtml is important and how it works.
