I painstakingly convert some PDFs from Boston and Massachusetts government into HTML and people prefer them for the flexibility and accessibility.
My workflow is to use pdftohtml then edit the result as Markdown and screenshot the figures before converting to HTML with pandoc.
I have been pushing to publish in HTML from the get-go, in part by citing this blog, with some success.
For example, the Massachusetts Secretary of the Office of Environmental Affairs recently published a typed letter as a raster PDF, which I converted into https://nattaylor.com/eastboston/blog/2019/3247-2017-logan-a... from https://eeaonline.eea.state.ma.us/EEA/emepa/mepacerts/2019/s...
