What Markdown features are supported?

All CommonMark Markdown syntax is supported: headings (# through ######), bold (**text** or __text__), italic (*text* or _text_), bold-italic (***text***), inline code (`code`), fenced code blocks (``` with optional language identifier), links ([text](url)), images (though external image URLs may not load — see the FAQ on images), blockquotes (>), ordered lists (1. 2. 3.) and unordered lists (-, *, +) including nested lists at multiple levels, horizontal rules (---), and tables using GitHub Flavored Markdown (GFM) table syntax with | as column separator. HTML tags embedded in Markdown are parsed but may not render as expected in the PDF output. All of these elements receive appropriate typographic styling in the output PDF.

Can I customize the PDF layout?

Yes. Three page sizes are available: A4 (the international standard used in most countries), Letter (the standard in North America), and Legal (8.5×14 inches for legal documents). Each size is available in both portrait and landscape orientation. Landscape is particularly useful for Markdown documents with wide tables or code blocks that would be truncated in portrait mode. The page margin is adjustable from 0mm to 30mm — a margin of 15–20mm is a comfortable default for readable documents, similar to standard word processor margins. These layout controls give you enough flexibility for most documentation, technical writing, and report use cases without requiring manual formatting.

Is my file uploaded to a server?

No. The entire Markdown-to-PDF pipeline runs in your browser using two open-source JavaScript libraries: marked.js (a fast, widely-used Markdown parser that converts Markdown syntax to HTML) and jsPDF (which converts the rendered HTML layout to a PDF byte stream). Your document content never leaves your device — no upload request is made, no server is contacted, and no data is transmitted at any point during conversion or download. You can confirm this by checking the Network tab in your browser's developer tools — you will see no outgoing requests for your document content. This makes the tool suitable for converting private technical documentation, internal wikis, personal notes, confidential technical specifications, and any Markdown content you would prefer not to send to an external service.

Will code blocks be formatted properly in the PDF?

Yes. Fenced code blocks (using triple backticks) are rendered in the output PDF with a monospace font (Courier New) and a light gray background color, making them visually distinct from surrounding prose text. Inline code (single backticks) is similarly rendered in monospace with a subtle background. The language identifier after the opening triple backticks (such as ```javascript or ```python) is recognized by the parser but syntax highlighting — color-coding of keywords, strings, and operators — is not applied in the current PDF output. Code renders as plain monospace text, which is appropriate for most documentation purposes. For PDFs with full syntax-highlighted code blocks in a range of colors, Pandoc with a LaTeX backend (via the --highlight-style option) is a more powerful command-line alternative that supports numerous highlighting themes.

Can I include images from my Markdown file?

Images referenced by external HTTPS URLs (![alt text](https://example.com/image.png)) may or may not load depending on the browser's CORS policy for locally loaded files — behavior varies across browsers and security settings. Images referenced as relative file paths (![alt text](./images/photo.png)) will not load because the browser cannot access other files on your local disk from within the page context. For reliable image inclusion in the converted PDF, embed images as Base64 data URIs directly in the Markdown: ![alt text](data:image/png;base64,iVBORw0KGgo...). Use ToolMint's Base64 Encode tool to convert your image file to a Base64 string, then paste it into the Markdown image syntax. This embeds the full image data in the Markdown file itself and guarantees it loads regardless of file location or network conditions.

What is the difference between this and using a browser's print-to-PDF?

Browser print-to-PDF requires several manual steps: first, open the Markdown file in a viewer that renders it (VS Code with Markdown preview, a browser with a Markdown extension, or GitHub), configure print settings in the browser's print dialog, then use Save as PDF. This multi-step workflow requires having a Markdown viewer installed and correctly configured, and the print dialog gives limited control over margins and page layout. ToolMint's MD to PDF tool handles the complete pipeline — parse, render, and export with layout controls — in a single browser tab visit with no additional software or configuration required. It is the fastest path from a raw .md file to a clean, well-formatted PDF, especially on computers where you do not have VS Code or a Markdown preview extension installed.

How It Works

1

Upload Markdown

Select or drag & drop your .md or .markdown file. The file is processed entirely in your browser using the marked.js parser and jsPDF library — no server is involved at any point, and your content never leaves your device. Plain text files using standard CommonMark or GitHub Flavored Markdown syntax are fully supported.

2

Choose Options

Select your preferred page size (A4, Letter, or Legal), orientation (portrait or landscape), and margin size in millimeters. These layout options let you match the output to your document's purpose — a wide landscape layout for technical documentation with wide code blocks, or a standard letter format with comfortable margins for business reports and proposals.

3

Download

Click Convert and the tool parses your Markdown using marked.js to produce HTML, then renders that HTML to a PDF using jsPDF with clean typographic styling. Headings are styled hierarchically, code blocks use a monospace font with background shading, and links are underlined. The PDF downloads automatically when rendering is complete.
