Oh interesting, I could’ve used this tool before. The best I found before was pdftohtml as well. Generally converting from PDF is awful. PDFs internally are more or less postscript which is like a little programming language that describes how to print things, as opposed to a markup language, so reverse-engineering the content can be whacky. If you haven’t used pandoc before that’s very useful in general (though not for PDf-to-other formats, you’ll need specialty tools like this) More on reddit.com

It's not a simple task. I'd break it into two parts. First extract the data you need from the pdf, and then generate a html file with that data. Hopefully all your PDFs follow the same template. Hopefully you can find a python library to first parse the pdf and extract the data, then you can use some kind of template language to generate html files from the data. If the PDFs are all different formats or are scanned images then this will be a very difficult task. But wait a minute, I just thought of something. If you open a pdf in chrome or Firefox, I think they convert the pdf to html to render it. You can right click on a pdf in Firefox or Chrome to see the html that the browser generated. If you dig into the browser's source code you might be able to find the bit that converts pdfs to html, and call it from your code. More on reddit.com

Try this , it just worked for me. More on reddit.com

The problem you're running into is the simple fact that PDFs store their information in a very different fashion than HTML documents. HTML documents pay more attention to content than layout. This includes organizing text into paragraphs and lines, and results in those documents rendering all sorts of layouts automatically. Most modern editable documents are based on XML, which is closely related. These documents convert pretty neatly to just about anything else, because the files are pretty much just instructions on how to display them. PDFs don't think about any of that. They rank layout above absolutely everything else, and that usually means things like breaking paragraphs up into individual lines, putting images on exactly the right spot every time, and generally making sure everything looks the same, regardless of what software or device you're using to open the document. Even if the PDF was generated from an XML-based document, the organizational information that lets a webpage render on-demand is discarded in favor of the layout data. Sometimes layout information might be included underneath everything else (like when a scanned PDF is made searchable - what's happening is that an OCR tool is reading the text and creating invisible lines of textual information underneath everything else), but there's no guarantee your converter of choice can properly interpret this information even when it is present. Now, there are some very spotty ways of working around this. Both Microsoft Office and Google Drive will attempt to read a PDF and make some assumptions about layout so that they can create a workable document from it, and some OCR solutions are getting better at doing the same. When these work, those generated documents translate easily to HTML, but that intermediary step is always going to be necessary for a PDF. More on reddit.com
