June 08, 2026 5 min read HTML-to-Image Tool

This tutorial covers how to get started with the html2image.net API — authentication, key parameters, and code examples. We also show why developers often end up choosing a simpler alternative.

Getting started with the html2image.net API

html2image.net (Free, basic HTML-to-image conversion) provides a REST API for basic html rendering. Here's how to set it up and make your first API call.

Authentication

Most html2image.net API requests require authentication via API key. You'll find your key in the html2image.net dashboard after signing up.

Making your first request

# html2image.net — example request curl -X POST https://api.html2image.com/v1/render \ -H "Authorization: Bearer YOUR_HTML2IMAGE_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
html — HTML string to render

Limitations to be aware of

No built-in batch endpoint.

A simpler alternative for HTML rendering

If you're using html2image.net 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
