A Markdown + CSS to PDF editor and previewer built for web typography.

P&P lets you turn Markdown and CSS files into paginated content and export them as print-ready PDFs. It is built on Paged.js and JavaScript, bringing web typography tools to physical page design.

Why use it? If you write in Markdown but want to publish physical books, zines, or any formatted PDFs, P&P bridges the gap. Instead of using proprietary design software like InDesign or word processors, you can use the web technologies you already know (MD(HTML)/CSS) to layout print-ready documents.

It is available in two versions:

• Web
  • Edit Markdown + CSS directly in the browser.
  • Preview and export PDFs in the browser.
  • Can be used locally or online.
• Desktop
  • Edit Markdown + CSS in the text editor of your choice (Obsidian, VS Code, etc.).
  • Preview and export PDFs in the browser via a local server.
  • Can be used only locally.

• Node.js (v20+ recommended) to run the local servers.
• A recent version of Google Chrome (required for accurate PDF rendering, and file loading/saving in the web version).

If you just want to explore P&P, use one of the templates available in the /templates folder:

• Demo: Works with the web and desktop versions.
• Starter: Works with the desktop version.

The template CSS files contain documentation/comments

• Accepts only remote images via URL.

• Accepts both remote and local images.
• Local images must be located in /your-work-folder or its subfolders.
• Supports subfolders.
• Accepts .js files (useful for passing Paged.js plugins).
• Note on file watching: The desktop version watches for file changes in /your-work-folder, but file changes in subdirectories are not automatically detected yet. If you update a file inside a subfolder, you need to manually refresh the webpage.

Before parsing, source files are sorted in alphanumeric order, including files in subfolders. The simplest way to order your files sequentially is to number them (e.g., 01-intro.md, 02-chapter.md). See the examples in /templates.
