HTML / Markdown to PDF
Free HTML & Markdown to PDF Converter — Live Preview, No Upload
Type Markdown or HTML on the left, preview the styled output on the right, then download as a print-quality PDF. Font, paper size, and orientation controls included.
About this tool
Every developer, writer, and analyst occasionally needs to turn a text document into a properly formatted PDF — whether for a report, a proposal, meeting notes, or technical documentation. The usual options involve pasting into Word, wrestling with formatting, or paying for an online converter that uploads your content to a server. This tool takes a different approach.
HTML / Markdown to PDF is a split-pane editor that runs entirely in your browser. Type or paste Markdown on the left and watch a styled PDF preview update in real time on the right. If you prefer to write raw HTML, flip the mode toggle and get full control over markup. When you are happy with the output, click Download PDF — a print dialog opens and you save the file directly to your computer using your browser's built-in print-to-PDF engine. No file is ever transmitted to a server.
The Markdown parser is the open-source marked library (CommonMark-compliant), so all standard syntax is supported: headings, bold and italic text, lists, tables, code blocks, blockquotes, and inline HTML. The preview iframe uses the same CSS that will be applied when printing, so what you see is close to what you will get.
A set of toolbar controls lets you adjust the output before downloading. Choose between Sans-serif, Serif, or Monospace font families, pick a font size from 11 px to 18 px, select A4, Letter, or Legal paper, and toggle Portrait or Landscape orientation. All these settings are applied via CSS @page rules so the browser's print engine honours them precisely.
Common use cases include writing quick technical reports in Markdown, converting meeting notes to a shareable PDF, producing formatted proposals from an HTML template, and generating documentation from content that already exists as HTML or Markdown in a code repository.

How to Use
- 1Choose your input modeUse the Markdown / HTML toggle in the toolbar to select how you want to write. Markdown mode (the default) is ideal for plain-text writing — headings, lists, bold, code blocks, and tables are written using simple syntax. HTML mode gives you full control if you already have markup or want to use inline styles.
- 2Write or paste your contentType directly in the left editor panel, or paste content from any source. The editor pre-fills with a sample document so you can see the supported formatting at a glance — select all and delete it to start from scratch. The preview on the right updates continuously as you type.
- 3Choose font and sizeUse the font family selector (Sans-serif, Serif, or Monospace) and the font size selector (11 px to 18 px) to match the typographic style of the document you need. The preview reflects both choices immediately so you can compare options before downloading.
- 4Set paper size and orientationSelect A4 (international standard), Letter (North American standard), or Legal from the paper size dropdown. Click the Portrait / Landscape button to switch orientation. These settings are embedded in the document as a CSS @page rule and are applied precisely by the browser when printing.
- 5Preview and fine-tuneReview the right-hand preview panel to check headings, table alignment, code block formatting, and overall spacing. Make any final edits in the left panel. Because the preview uses the same CSS as the print output, what you see here is representative of the downloaded PDF.
- 6Download the PDFClick "↓ Download PDF" in the toolbar. A new window opens showing your formatted content, and the browser's print dialog appears automatically. In the destination selector, choose "Save as PDF" (Mac / Chrome), "Microsoft Print to PDF" (Windows), or your system equivalent. Give the file a name and click Save.
Common Use Cases
Frequently Asked Questions
The tool works entirely in your browser. When you type Markdown, it is converted to HTML in real time using the open-source marked library. That HTML — along with your chosen font, font size, paper size, and orientation — is wrapped in a complete print-ready HTML document and shown in the preview iframe on the right. When you click Download PDF, a new window opens with the styled content and the browser's print dialog is triggered automatically. Choose "Save as PDF" (or "Microsoft Print to PDF" on Windows) to save the file.
No. Everything runs locally in your browser. Your Markdown or HTML text never leaves your device — it is parsed and rendered in memory, the print window is opened client-side, and the resulting PDF is saved directly to your computer by the browser. No data is transmitted to any server at any point.
The tool uses the marked library, which implements the CommonMark specification. All standard Markdown is supported: headings (# H1 through ###### H6), bold and italic text, inline code and fenced code blocks, ordered and unordered lists, blockquotes, horizontal rules, links, images, and tables using the GFM (GitHub Flavored Markdown) table extension. HTML can also be embedded directly in Markdown documents and will be passed through.
Yes. Use the Markdown / HTML toggle in the toolbar. Switching from Markdown to HTML converts your current content to HTML so you can see and edit the raw markup. Switching back to Markdown resets the editor to the sample document, because there is no general-purpose HTML-to-Markdown converter in the browser. If you have important content, copy it out before switching modes.
You can choose between A4 (210 × 297 mm), Letter (8.5 × 11 in), and Legal (8.5 × 14 in) paper sizes, and toggle between Portrait and Landscape orientation. These settings are passed to the CSS @page rule in the print document, so the browser honours them when printing to PDF. The margins are set to 20 mm by default, giving comfortable whitespace on all four sides.
Three font families are available: Sans-serif (the default, using system UI fonts like Segoe UI on Windows and -apple-system on macOS), Serif (Georgia / Times New Roman for a traditional document look), and Monospace (Courier New for technical or code-heavy documents). Font size can be set from 11 px to 18 px. Because these are system fonts, they are available on all devices without any download.
Click "Download PDF" in the toolbar. A print dialog opens in a new window showing the rendered content. In the destination selector, choose "Save as PDF" on Mac or Chrome, "Microsoft Print to PDF" on Windows, or your system's equivalent. Set your preferred file name and click Save. The PDF is created entirely by your browser's built-in print engine, so the output quality matches what you would get from printing any styled web page.
The preview is a live iframe rendering the same HTML and CSS that will be used for printing, so the typography, headings, tables, and code blocks should match closely. However, because the preview iframe does not apply @page margins (those only activate during printing), the page boundaries and final line breaks may differ slightly from the printed output. For a fully accurate proof, use the browser's print preview before saving.
Yes, in both modes. In Markdown, use the standard image syntax: !alt text. In HTML mode, use a standard <img> tag. Images must be reachable as public URLs or data URIs — local file paths will not work because the print window is a separate browser context. Base64 data URIs are the most reliable way to embed images that are not hosted online.
Completely free. No account, no email address, no sign-up of any kind. Open the page and start typing. Because all processing happens in your browser, there are no server costs and therefore no usage limits or premium tier.
