One possible point to start is using pdf2dom . Please have a look here for how to integrate the dependencies into your project and to read more about possible required dependcies.

Pdf2Dom provides a PDF parser that converts the documents to an HTML DOM representation. This DOM tree then can be serialized to an HTML file or used for further processing.

Here's a small code example, I tried it and it worked well:

    private void convert() {
    try {
        PDDocument pdf = PDDocument.load(new File(SOURCE_PDF));
        PDFDomTree parser = new PDFDomTree(PDFDomTreeConfig.createDefaultConfig());
        Writer output = new PrintWriter(TARGET_HTML, "UTF-8");
        parser.writeText(pdf, output);
        output.close();
        pdf.close();
    } catch (IOException | ParserConfigurationException e) {
        // Handle errors
    } 
}
