The Allen Institute for AI has a new prototype Academic Paper to HTML converter, as an online service.

There are of course already polished online services such as a IDR’s PDF to HTML5, but they limit the number and size of uploads.

Such conversions can also be done on a desktop PC via QuarkXPress 2021, which does quick pixel-perfect HTML5 conversion natively and (if you wait for a Black Friday discount) can be had for about £180 on a perpetual licence. Its direct competitor Adobe InDesign is subscription and needs a further expensive plugin (also subscription) to do HTML5 output. Many old-timers will throw up their hands in horror at the name ‘QuarkXPress’, but it’s no longer your grandpa’s creaky old DTP software.
