Tool overview​

Convert any Markdown to a beautiful PDF document locally in your browser. This tool enables developers, writers, and technical authors to render and download markdown as clean, formatting-rich PDF files entirely offline.

What the tool does​

• Provides a dual-pane markdown editor and real-time preview viewer.
• Generates high-quality PDFs preserving formatting, lists, tables, and headers.
• Allows you to upload existing .md or .txt files directly.

What problems it solves​

• Removes the need for messy server-side printing.
• Helps technical writers export their documentation accurately without complex terminal setups.
• Ensures 100% privacy since your text and documents never leave your browser.

Who should use it​

Developers, technical writers, bloggers, students, and system administrators who maintain documentation in markdown and need reliable PDF exports.

Why it matters​

Privacy and accurate rendering is crucial for proper documentation sharing. This simple client-side solution handles everything fast without compromising sensitive or proprietary content.

How It Works​

Input​

You can type standard Markdown into the editor pane, paste markdown text, or upload an .md file.

Processing​

A fast real-time parser (marked) translates your markdown to styled HTML instantly. Once you click "Download", it captures a snapshot of the rendered output using an off-screen engine.

marked follows the CommonMark spec with GitHub Flavored Markdown (GFM) extensions enabled. The parsing pipeline is:

1. Lexer - tokenises the raw markdown string into a flat token list (headings, paragraphs, code fences, table rows, etc.)
2. Renderer - walks the token list and emits HTML strings; code fences are wrapped in <pre><code> with language class attributes for syntax highlight CSS
3. HTML injection - the rendered HTML is written into a hidden <div> in the page DOM, with a bundled stylesheet applied for typography, table borders, and code block background colours
4. Canvas capture - html2canvas traverses the DOM node, resolves CSS, and rasterises the styled content to an off-screen <canvas> at the page width
5. PDF encoding - the canvas bitmap is encoded as a JPEG (for file size) and embedded into an A4 PDF via jsPDF, with automatic page-height slicing

This pipeline means the output PDF is an image-per-page, not a text layer - characters are not selectable. If you need selectable text, use the Plain Text to PDF tool.

Limitations​

• The styling is currently hard-coded to a clean layout suitable for most professional outputs.
• Deep nested structures, complex flowcharts, or Mermaid.js specifically may not render correctly unless typed as standard markdown.

Output​

A high-resolution A4 PDF file formatted properly and automatically saved to your hard drive.

Frequently Asked Questions​

Is my data secure?​

Absolutely. The entire conversion from Markdown to PDF is handled by JavaScript running directly in your web browser. No data is sent to external servers.

Are Markdown tables supported?​

Yes, standard HTML table syntax from Github Flavored Markdown is translated properly.

How does this differ from the Plain Text or Rich Text converters?​

marked parses Markdown syntax - #, **bold**, ``` code fences, | table pipes - which plain text and WYSIWYG editors do not understand. Use this tool when your source is .md files. Use Rich Text to PDF if you are pasting from Word or Google Docs. Use Plain Text to PDF if you need a selectable, copy-pasteable text layer in the output PDF.

Does code syntax highlighting work?​

Yes, code fences are styled with a dark background and monospace font via the bundled stylesheet. Colour-based syntax highlighting is not currently applied - all code tokens render in the same colour.

Are Mermaid or LaTeX diagrams supported?​

No. marked renders standard GFM only. Mermaid.js diagram blocks and LaTeX math expressions ($$...$$) are not processed and will appear as raw text or empty blocks.
