Built for real HTML, not a stripped-down subset

Full CSS, real Chromium

PDF output is generated in a real headless Chromium instance — flexbox, custom fonts, gradients, the full Tailwind utility set. It's not a limited HTML-to-image approximation.

A4, Letter, or custom pixels

Use the a4 or letter dimension presets for print-ready output, or pass an exact width and height in pixels for anything else.

Stateless & synchronous

No job queue and no polling for a result — the finished PDF binary comes back in the same request that triggered it.

How it works

1
Write your HTML or Tailwind template
Anything that renders correctly in a browser — a report, a contract, a certificate — is valid input. No special markup dialect to learn.

POST it with format: "pdf"

Call the render endpoint with your content and the a4 or letter dimension preset.

curl -X POST https://renderfy.io/api/v1/render \
  -H "Authorization: Bearer rfy_live_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "type": "tailwind",
    "content": "<div class=\"p-10\">Your report HTML here</div>",
    "options": { "format": "pdf", "dimensions": "a4" }
  }' \
  --output report.pdf

3
Store, email, or stream it straight through
The response body is the finished PDF — attach it to an email, upload it to object storage, or stream it directly to your user.

Frequently asked questions

Can I use Tailwind classes directly in the HTML I send?+

Yes. The PDF path renders through a real headless Chromium instance loading the full Tailwind CSS engine, so every utility class works — not just a limited subset. (The separate PNG/JPEG image path uses a lighter Tailwind-compatible parser with a few small gaps; the PDF path has no such limits.)

What page sizes are supported?+

The a4 and letter dimension presets cover standard print sizes out of the box. You can also pass an exact width and height in pixels for any non-standard page size.

Do I need to run or manage a headless browser myself?+

No. Chromium runs server-side and is reused across warm invocations — there's nothing for you to install, patch, or keep alive.

Can I convert an existing HTML report or invoice template?+

Yes. If your existing template renders correctly in a browser today, it will render correctly through this API — no rewrite required.
