About Markdown to PDF

Turn any Markdown document into a polished PDF without leaving your browser. Drop in a .md file or paste straight into the editor, watch a live preview update in real time, and click Export to send a beautifully typeset version to your browser's print dialog where you can save it as a PDF or send it directly to a printer. The output mimics the typography of MD Peek on iOS — a generous serif body face, a sans-serif heading rhythm, soft rounded code blocks, hairline tables, and a warm blockquote bar — instead of the stark default browser styling that makes most online converters look like school worksheets. GitHub-Flavored Markdown features are fully supported: tables, task lists rendered as Unicode glyphs that print consistently across browsers, fenced code blocks with Shiki syntax highlighting across roughly twenty popular languages, strikethrough, autolinks, and footnotes. Because the conversion happens entirely client-side, your writing never leaves your device — useful for confidential notes, technical specs, meeting minutes, exam answer keys, freelance invoices, or any draft you would rather not upload to a stranger's server. The resulting PDF carries selectable text, vector code blocks that scale crisply at any zoom, and small file sizes (typically 50 to 500 KB), all in a layout tuned for readable long-form prose.

Frequently Asked Questions

Why does the print dialog open instead of an instant download?

The browser's native print engine is the only way to produce a PDF with selectable text, embedded fonts, and crisp vector code blocks. Pick 'Save as PDF' (Chrome/Edge), 'Save to PDF' (Safari), or 'Save to File' (Firefox) as the destination — the rest of the layout is already taken care of.

Does it support GitHub-Flavored Markdown?

Yes. Tables, fenced code blocks, task lists (rendered as Unicode glyphs so they print consistently), strikethrough, autolinks, and footnotes are all handled. Standard headings, lists, blockquotes, images, and inline emphasis work as expected.

What languages are syntax-highlighted in code blocks?

About twenty popular languages out of the box: js, ts, tsx, jsx, py, go, rust, java, c, cpp, json, yaml, toml, bash, sh, sql, html, css, md, and diff. Code fences with an unrecognised language fall back to plain monospace without throwing.

Can I customize the styling?

Yes — toggle between Light and Dark themes and between a Serif body (default, MD Peek-inspired) and a Sans body. Margins, page size (A4 by default), and code-block colors are tuned for legible long-form prose; per-document custom CSS is on the roadmap.

Why are colors missing from my exported PDF in Firefox?

Firefox disables 'Print backgrounds' by default, which strips the code-block backgrounds and table headers from the print preview. Toggle 'Print backgrounds' (or 'Print background graphics') in the print dialog before saving to fix it.

Is my file uploaded to a server?

No. Transmute processes everything locally in your browser using JavaScript and the Canvas API. Your files never leave your device — there is no server, no upload, no cloud processing.
