wtf is markdown-to-pdf?

MarkdownToPDF is a free, browser based tool that converts Markdown documents into several other formats: Word (.docx), PDF, HTML, and images. According to the README, the entire conversion process happens locally in the user's browser, with no files uploaded to any server, no account registration, and no installation required. A live demo is hosted at markdown-to-pdf.ideaseek.cn. The README lists a real time preview with a 150 millisecond debounce so the rendered output updates as the user types, syntax highlighting for more than 190 programming languages through highlight.js, and support for LaTeX math formulas rendered with KaTeX. For exporting, Word documents are generated by converting the page's HTML structure directly into native DOCX formatting using the docx library, PDF export relies on the browser's built in print function laid out for A4 paper, and images can be exported as PNG, JPG, or WebP at double pixel density using the html-to-image library. The project is built with Vite and TypeScript, and uses the browser's History API for client side routing rather than a full page reload framework. Markdown parsing is handled by the marked library along with a syntax highlighting plugin for it. The README states the project is developed and maintained by a company called ideaseek, described in the README as Zhuhai Zhixun Technology Co Ltd. The codebase is organized as a single page application with a main HTML entry point, a small router module, and a core folder containing separate modules for Markdown parsing, math rendering, and each export format. This tool is aimed at anyone who writes in Markdown and needs a quick, free way to convert it into a shareable document format without installing desktop software or trusting a server with their content.
