HTML to PDF in Java

Generate pixel-perfect PDFs from HTML or any URL in Java — without running Puppeteer yourself. One POST to RenderKit returns a signed PDF URL with real Chromium print CSS.

Self-hosting headless Chrome in Java means a memory-leaking browser process you restart at 2am. RenderKit's /v1/pdf endpoint is the managed alternative: POST a JSON spec, get a signed PDF URL back. Print CSS, custom page size, margins, and running headers/footers are all supported.

Java example

pdf.java
HttpRequest req = HttpRequest.newBuilder()
  .uri(URI.create("https://api.renderkit.tech/v1/pdf"))
  .header("x-api-key", key).header("content-type", "application/json")
  .POST(BodyPublishers.ofString("{\"url\":\"https://example.com\"}"))
  .build();

What's included

  • Chromium print pipeline — real @media print, not an HTML approximation
  • Custom page size, margins, landscape/portrait, print-background
  • Running headers/footers with page numbers
  • Signed CDN URL response — stream it or redirect to it
  • Same key also does screenshots and markdown extraction

Common questions

POST your URL or raw HTML to RenderKit's /v1/pdf endpoint with your API key. The response is a signed URL to the generated PDF — no headless browser to install or host in Java.

No. RenderKit hosts the browser fleet. You send a JSON request and receive a finished PDF, which removes the memory and concurrency problems of self-hosting.
