What does Rendex do?

Rendex is a rendering API that turns HTML, URLs, and Markdown into images or PDFs. You send a POST request with your content, and it returns a PNG, JPEG, or PDF — no need to manage a browser farm or deal with headless Chromium yourself. The service handles viewport settings, device emulation, full-page scroll-stitching, and even blocks ads and cookie banners automatically. It's built for automation workflows, with native integrations for n8n, Make, Zapier, and an MCP endpoint so AI agents like Claude can call it as a tool.

What makes Rendex stand out is its simplicity and reliability. You don't provision infrastructure or worry about browser crashes — each request runs in a fresh worker, so a bad page can't poison the next. The API supports templating with a data object, so you can generate branded PDFs from a template and dynamic values. It also offers hosted URLs for sharing, extraction of clean Markdown from rendered pages, and batch processing. The playground on the site lets you toggle capabilities like dark mode, full page, or geo-targeting and see the result instantly.

Rendex is most useful for developers building automated reporting systems, social media preview generators, or monitoring tools that need screenshots. AI agents can use it to produce visual outputs like charts or invoices. If you need to turn a web page or HTML snippet into a consistent image or PDF without running your own rendering infrastructure, Rendex does the job with a single API call.
