Three steps. Five minutes to integrate.

No SDKs required. If you can make an HTTP request, you can generate PDFs.

01

Get your API key

Sign up, grab your key, and you're ready. No credit card required for the free tier — 100 PDFs/month, no strings.

02

POST your HTML + data

Send your HTML/CSS template and a JSON payload with dynamic values. We use Chromium under the hood — if it looks right in Chrome, it'll look right in your PDF.

03

Get back a PDF

Receive a production-ready PDF in the response body. Or get a signed URL to download it later. Average render time: 1.5 seconds.

Built for developers who ship fast

We obsess over the things that actually matter to you: speed, reliability, and docs you can actually read.

Sub-2-second renders

Chromium-powered rendering with aggressive caching. Most PDFs return in under 1.5 seconds.

📖

Docs that don't suck

Copy-paste examples in curl, Node, Python, Go, and Ruby. First PDF in under 5 minutes, guaranteed.

🔧

Full CSS support

Flexbox, Grid, custom fonts, media queries — if Chrome renders it, we render it. No weird layout quirks.

🔒

Your data, then gone

PDFs are encrypted in transit and at rest. We auto-delete generated files after 24 hours. No data retention.

📐

Page size & margins

Letter, A4, custom dimensions — set page size, margins, headers, and footers via simple JSON params.
