Markdown to PDF Converter

PDF is a practical final format when a document must look consistent for readers who do not use Markdown. It opens on phones, tablets, and desktop systems, prints predictably, and is difficult to alter accidentally. This converter begins with a live Markdown preview so you can inspect the document before creating the file. The preview is important: it shows the exact heading structure, tables, code highlighting, formulas, and supported diagrams that the PDF service will receive.

Unlike a simple text-to-PDF operation, the export starts from rendered HTML. The page sends the finished preview and the styles required for it to the site PDF endpoint. A headless Chrome browser lays the content out on pages and returns the generated PDF to your browser for download. The source Markdown is not written into a project or database by this flow, but the rendered content does travel to the server temporarily for generation.

Paste Markdown or import a local .md or .txt file in the workspace above. Review the right-hand preview and fix any malformed table separators, unmatched math delimiters, wrong code-fence language names, or diagrams that are wider than the document. When the page looks correct, choose Export to PDF. The browser sends the rendered preview to the PDF endpoint, waits for Chrome to finish pagination, and downloads the result as markdown-viewer-document.pdf.

Large diagrams, long unbroken code lines, and very wide tables can require extra attention because a PDF page has a fixed width. Keep code examples reasonably wrapped, use concise table columns, and verify diagrams in the preview before exporting. The current interface uses a print-oriented page layout rather than exposing a large set of paper and margin controls. If a document needs a custom publishing template, export HTML and apply a dedicated print stylesheet instead.

Headings, paragraphs, emphasis, lists, links, blockquotes, tables, and code blocks receive print-friendly styling. Code syntax colors are copied or supplemented with a basic highlight palette. MathJax formulas are already rendered as SVG in the preview, which allows fractions, roots, matrices, sums, integrals, and other notation to remain clear. Mermaid and Vega graphics that have finished rendering in the preview are part of the preview DOM sent to the server.

The service registers a bundled Chinese font in its serverless Chrome environment so Chinese text can appear even when the host system has no CJK fonts installed. The output is still generated from web content, so results can differ from a desktop publishing application in exact line breaks, font metrics, or complex page-break decisions. The safest workflow is to open the downloaded PDF and check the final pages before distributing it.

Use PDF for a report that will be printed, a lesson handout, a product brief, a technical note sent to a customer, a portfolio sample, or a stable archive copy. It is also useful when the recipient should read the content without needing a Markdown editor. PDF is less suitable when collaborators must keep revising paragraphs or extracting structured source. For editable office workflows, use the Markdown to Word page. For publishing on the web or applying custom CSS, use the Markdown to HTML page.

The converter remains free to use and does not require account creation. Autosaved source stays in local browser storage. Only the PDF action sends rendered content to the server, and that distinction is stated here so you can choose a format that matches the sensitivity and workflow of the document.
