Markdown to PDF API
Ship docs and changelogs as clean PDFs
Write plain Markdown — headings, lists, code blocks — and get back a formatted, print-ready PDF. No template to design, no Pandoc install, no separate conversion library.

Standard Markdown in
Headings, bold and italic text, lists, code spans, and blockquotes all render exactly as expected — the syntax you already write for READMEs.
No template required
Unlike the HTML/Tailwind engine, there's nothing to design first — document structure comes straight from the Markdown headings and lists.
Same input, PNG or PDF
Render the same document as an image for an inline preview, or as a PDF for a downloadable, archival copy.
How it works
- 1
Take Markdown you already have
A README, a changelog, a wiki export — any Markdown document you'd already commit to a repository is valid input.
- 2
POST it with type: "markdown"
Choose png for a quick preview image, or pdf for a downloadable document.
curl -X POST https://renderfy.io/api/v1/render \ -H "Authorization: Bearer rfy_live_YOUR_KEY" \ -H "Content-Type: application/json" \ -d '{ "type": "markdown", "content": "# Release Notes\n\n- Fixed a bug\n- Shipped a feature", "options": { "format": "pdf", "dimensions": "a4" } }' \ --output release-notes.pdf - 3
Serve or archive the result
No separate Markdown-to-PDF library, Pandoc binary, or wkhtmltopdf install required in your own stack.
Frequently asked questions
Does it support nested lists and tables?+
Top-level lists render fully on both output paths. Deeply nested lists render most reliably through the PDF path — it renders through a full browser engine rather than a simplified layout pass.
Can I include code blocks in the Markdown?+
Yes. Fenced code blocks render as monospaced blocks in the output document, preserving indentation and line breaks.
Is this the same engine used for README files?+
Yes — any Markdown you'd already commit as a README, changelog, or wiki page is valid input with no modification needed.
PNG or PDF — which should I use for a changelog embed?+
Use PNG for an inline preview image inside a page or email, and PDF when you want a downloadable, archival copy — both come from the same Markdown input.
