Show HN: Markdown Viewer with LaTeX Math Support and Export to PDF/Word/HTML

Posted by LuckyBuddy on Sunday January 25, 2026 @01:52AM
from the show-hn dept.

I found that most online Markdown tools don't render math formulas properly.

Features:

Full LaTeX math support (inline and block) Export to PDF, Word (.docx), and HTML Copy as rich text (paste directly into emails, docs, etc.) No login required, works entirely in browser

Cool. How do you have implemented the latex rendering? Are you using one of the common libraries? Is the rendering (incl. PDF etc.) directly running in the browser, or on the server?

Thanks for your reply.

I'm using MathJax (mathjax-full) to render LaTeX. For browser preview, it converts LaTeX to SVG on the client side.

For PDF export, the rendered HTML (with SVG math) is sent to the server where Puppeteer generates the PDF.

Interesting, thanks. So you need a Node based server to run it.

The main technology stack is Next.js.
