Are you referring to converting an existing webpage into an image, or do you want to render HTML code directly into an image?

The fastest way to convert styled HTML (HTML + CSS, including <img> tags) to an image is Puppeteer, a Node.js library leveraging Chromium’s optimized rendering engine. It works in headless mode for minimal overhead and high performance. Why Puppeteer is Fast: 1. Native Rendering: Chromium processes modern CSS/HTML efficiently. 2. Minimal Setup: No drivers or additional configuration required. 3. Speed: Outputs in under 100ms, outperforming alternatives like imgkit (~300ms) and Selenium (~400ms). Puppeteer ensures accuracy and speed, making it ideal for converting styled HTML into images.

Solution: Puppeteer with Headless Chrome Why Puppeteer? • Speed: It directly utilizes Chrome’s rendering engine, optimized for HTML and CSS rendering. • Accuracy: Full support for modern HTML/CSS, including <image> tags, layering, and animations. • Cross-platform: Works on Windows, macOS, and Linux. Benchmarks • Puppeteer Execution Time: Around 500ms to 1 second for rendering and screenshotting. • Alternative Comparisons: • WKHTMLtoImage: Slower (~2-3 seconds) and limited modern CSS support. • HTML2Canvas (Browser-side): Limited to in-browser use and slower for complex layering. • Custom Renderers: Rarely match Puppeteer’s rendering accuracy and speed. Why it Works 1. Library Functionality: Puppeteer is actively maintained, well-documented, and widely used. 2. Proven Speed: Chrome’s rendering engine ensures the fastest possible rendering times.

Also, just want to mention the fastest in absolute (if your page fits in your display): render the HTML and take a screenshot of your desktop 🤣

Hey fam, If you want to convert styled HTML (including CSS and images) to an image quickly and efficiently, you should use Puppeteer with Node.js. Puppeteer is actually a headless browser library for Node and yeah it can render HTML/CSS accurately and even save it as an image file. Here's a code Example using Puppeteer (Node.js) const puppeteer = require('puppeteer'); const fs = require('fs'); (async () => { const browser = await puppeteer.launch(); const page = await browser.newPage(); // Load HTML content const htmlContent = ` <html> <head> <style> /* Your CSS here */ </style> </head> <body>  </body> </html> `; await page.setContent(htmlContent); // Set viewport for full content rendering await page.setViewport({ width: 800, height: 600 }); // Save as image await page.screenshot({ path: 'output.png', fullPage: true }); await browser.close(); })();

Cheap shot, but Satori is industry standard imo. Turns html + css into SVGs (and with another library you can turn those into PNGs or other image formats). Runs server side, pretty easy to use, and can even do tailwind styling. Example: https://stevedylandev-visionaryazureswordtail.web.val.run/ https://github.com/vercel/satori With that said would be interested to see what others mention 👀

If you're optimizing for speed, I would not introduce additional libraries like Puppeteer. The fastest way is to server-side render and run headless browser on the machine and call the browser's screenshot command directly. We use firefox because it's accelerated out of the box without additional config. You can do this with chrome as well, but requires additional flags. The performance difference is negligible. ``` firefox -headless --window-size=1910,1000 -screenshot ``` This works: we're doing this in production for scoreclips. This is a rendered HTML template (there's some overhead in the example to actually fetch the data, but the image rendering is very fast). Example: https://merlot.bunches.io/app/scoreclip/ccb6079b-5975-4b24-9108-5fc99b47e9c3 Happy to answer any additional questions! @derek
