print-mark

A web app that converts Markdown to clean, printable HTML with PDF export. It offers live preview with real-time rendering, nine print-optimized themes, syntax highlighting powered by Shiki, and drag-and-drop upload of .md, .markdown, or .txt files. PDF export generates documents with customizable page sizes, margins, and page numbers, and the design is stateless with no account required. It can be run via a pre-built Docker image, docker-compose, or locally with Node.js, and exposes configuration through environment variables such as PORT, PDF_TIMEOUT, and PDF_CONCURRENT_LIMIT.
