Chromiumly integrates with Gotenberg to convert URLs, HTML, Markdown, and office documents to PDF, and runs on Node.js, Deno, and Bun. Use the hosted API at api.chromiumly.dev with an API key, or run Gotenberg yourself (self-hosted).

​
What you can do

  • Chromium: Convert URLs, HTML, and Markdown to PDF; capture full-page screenshots as PNG, JPEG, or WebP.
  • LibreOffice: Convert DOCX, XLSX, PPTX, and other office formats to PDF.
  • PDF engines: Convert to PDF/A and PDF/UA, merge PDFs, read/write metadata, split, flatten, and more.
Chromiumly wraps Gotenberg’s API; for server-side configuration, limits, and troubleshooting, see Gotenberg’s documentation.

​
Hosted API vs self-hosted

Use the hosted API with an API key: sign up at chromiumly.dev, set CHROMIUMLY_API_KEY or Chromiumly.configure({ apiKey: "..." }), and start converting. No Docker or server to run.
