RenderPix is an HTML-to-image rendering API built for developers. Send raw HTML via a simple POST request and receive a pixel-perfect PNG, JPEG, or WebP in return. Powered by a pre-warmed Chromium pool โ no cold starts, no queue delays. Supports full-page screenshots, CSS selector capture, and retina scaling (up to 3x). Language-agnostic, framework-agnostic. Start free, scale as you grow.
Indie developers and small SaaS teams (1โ5 engineers) who need to generate images programmatically โ OG images, invoices, certificates, social cards โ without maintaining their own headless browser infrastructure.
RenderPix takes a "Bring Your Own HTML" approach โ no template engine, no visual editor, no lock-in. You send raw HTML and get back a pixel-perfect image. The pre-warmed Chromium pool eliminates cold starts, delivering renders in ~230ms.
RenderPix is significantly cheaper than alternatives like htmlcsstoimage.com or Bannerbear, while giving developers full control over their HTML and CSS. No templates to learn, no proprietary DSL โ if it renders in Chrome, it renders in RenderPix.
RenderPix was built to solve a recurring problem in web development: generating images from HTML requires either a fragile self-hosted Puppeteer setup or expensive template-driven services. RenderPix offers a clean middle ground โ a simple API that stays out of your way.
