Stop babysitting a PDF service

Generating PDFs in your app usually means running headless Chrome or Puppeteer in production, fighting wkhtmltopdf over broken CSS, or wiring up a heavy enterprise API. You maintain the infrastructure, it breaks under load, and the output still looks off.

No headless Chrome or Puppeteer to deploy, scale, or patch
No HTML pre-processing — send Markdown directly
Consistent output: tables, code, diagrams, and math just work

Frequently asked questions

How do I authenticate?: Pass your API key as a bearer token in the Authorization header of each request.
What are the rate limits?: Each plan includes a monthly call allowance: 25 on the free tier, 500 on Starter, and 1,000 on Pro.
How fast is a conversion?: Most documents convert in a couple of seconds.
Do you store my content?: No. Your Markdown and the generated PDF are held in memory only long enough to return the response, then discarded — and we never train on your content.
Which Markdown is supported?: GitHub-flavored Markdown, plus Mermaid diagrams, syntax-highlighted code, and LaTeX math.
What happens if I exceed my plan?: Calls past your monthly allowance return a clear limit response. Top up with a credit pack or upgrade anytime.
