Hey there! I totally get your frustration—saving a Word doc with MathType formulas directly as a webpage gives those blurry, low-res images that look terrible, especially when you’re trying to keep things professional. Since you’re new to this, let’s stick to straightforward, no-fuss methods that don’t require rebuilding everything from scratch:

• 先把MathType公式转成结构化格式（关键第一步）
  Open your .docx document, select all the MathType formulas. In the MathType toolbar, go to Convert → Convert to MathML or TeX, and pick MathML. This turns those formula images into structured, machine-readable content that will render crisply in HTML, instead of being locked as low-res pictures.

• 用Pandoc转换（简单命令行，效果稳定）
  Pandoc is a fantastic tool for converting between document formats, and it handles MathML really well. First, install Pandoc (just grab the official installer and go with default settings—super easy for beginners). Then open Command Prompt (Windows) or Terminal (Mac/Linux), and run this command:
  pandoc -s your-document.docx -o output.html --mathml
  Replace your-document.docx with the path to your Word file, and output.html with whatever name you want for your final HTML. The --mathml flag tells Pandoc to keep the MathML formulas intact, so they’ll render as sharp, scalable elements in your browser.

• 用LibreOffice（完全免费，GUI操作，适合怕命令行的新手）
  If command lines feel intimidating, LibreOffice is your friend. It’s a free, open-source office suite that handles Word docs and MathML perfectly:

  1. Download and install LibreOffice, then open your .docx file in LibreOffice Writer.
  2. Go to File → Export As → Export as HTML.
  3. In the export settings window, look for the Formulas dropdown and select MathML instead of "Images". Hit export, and you’ll get an HTML file with crisp, scalable formulas.

A quick note: Most modern browsers (Chrome, Firefox, Edge) support MathML natively, so your formulas will look great right out of the box. If you ever need to support super old browsers, you can add a tiny MathJax script to your HTML, but that’s probably unnecessary for most use cases.
