With the dawn of advanced AI tools that can produce text, many are far better at generating brilliantly formatted HTML structurally than they are at generating raw PDFs directly. As a perfect middle ground, we've created the HTML Viewer Engine: a powerful, local-storage-first web application designed to let you cleanly paste your AI-generated HTML documents, edit them in an embedded VS Code environment, and flawlessly print them out for a streamlined workflow without any page cutoffs!
Live Deployment: https://html.entix.org
This tool is open-source and intended to help anyone stream-line handling raw HTML documents. If you are using this app and think it could use another feature, please create a Pull Request! We openly welcome and invite community contributions, tweaks, and additions.
- Perfect A4 Pagination & Printing: Prints HTML strings through an isolated invisible sandbox that automatically overrides broken line spacing. It intelligently injects native CSS (
break-inside: avoid) to prevent block elements, images, grids, and headings from being physically chopped in half over two pages when printed. - Displays Exact Document Names: The generated printouts accurately output the name of the document to the PDF header instead of generic system names.
- Monaco Code Editor: A fully-fledged VS Code environment physically embedded in the browser featuring beautiful syntax highlighting.
- Prettier Auto-Formatting: Automatically formats messy, minified, or disorganized inline HTML via Prettier's standalone engine with the click of a button.
- World-Class UI & Dark Mode: Uses highly polished Ant Design React layout elements beautifully mixed with Tailwind CSS. Seamlessly toggles between a vibrant Emerald/Purple Light state and a hyper-readable Dark Mode.
- Framework: React 19 + Vite (Optimized for V8 Isolates & Cloudflare)
- Routing: React Router v7 (HashRouter for serverless edge deployments)
- Styling: Tailwind CSS v4 + Ant Design (ConfigProvider Themed)
