How to transfer document from word to html?

Question

HTML

There is an instruction for more than thirty pages, written in word. Accompanied by drawings, captions, headings and subheadings, there is a table of contents.
Task: convert the instruction to html, so that later it can be embedded into a mobile application.
During conversion, part of the design is predictably lost and changed. What is better to use? Perhaps there are some ways easier than editing the finished html after conversion?

Answer 2

There is such a wonderful thing as Pandoc ! It seems that everything is fine with her pictures (markup and table of contents, if not very sophisticated, then they will not suffer). For mathematical texts - the best tool. For me personally, Pandoc is the best converter for text formats. Try it.

Answer 3

It seems to me the most reliable option is to print to a file. In the form of pictures. And show pictures from the application. So at least there is a guarantee that the formulas and graphs will keep the proportions and will not be lost. All other converters can break or lose something.
