URL2PNG API Tutorial (2026): Setup, Examples, and a Simpler Alternative

June 08, 2026 5 min read Screenshot API

This tutorial covers how to get started with the URL2PNG API — authentication, key parameters, and code examples. We also show why developers often end up choosing a simpler alternative.

Getting started with the URL2PNG API

URL2PNG (CDN-backed screenshot service with hotlinking support) provides a REST API for url screenshots. Here's how to set it up and make your first API call.

Authentication

Most URL2PNG API requests require authentication via API key. You'll find your key in the URL2PNG dashboard after signing up.

Making your first request

# URL2PNG — example request curl -X POST https://api.url2png.com/v1/render \ -H "Authorization: Bearer YOUR_URL2PNG_KEY" \ -H "Content-Type: application/json" \ -d '{"url": "https://example.com", "width": 1200, "height": 630}'

Key parameters

width / height — output image dimensions
format — PNG, JPEG, or WebP
url — URL of the page to capture

Limitations to be aware of

No raw HTML input — you must host the content before capturing it. No native n8n or Make.com node. No built-in batch endpoint.

A simpler alternative for HTML rendering

If you're using URL2PNG specifically for HTML-to-image rendering and find the setup complex, RenderPix offers a simpler API with native n8n support:

# One API call. That's all. curl -X POST https://renderpix.dev/v1/render \ -H "X-API-Key: YOUR_KEY" \ -H "Content-Type: application/json" \ -d '{ "html": "<div style=\"width:1200px;height:630px;background:#0f0f0f;color:#fff;display:flex;align-items:center;justify-content:center;font-size:48px\">Hello, RenderPix</div>", "width": 1200, "height": 630, "format": "png" }' --output card.png
