How the HTML to Image Converter works

Paste any HTML markup and CSS rules into the two editors on the left — the panel on the right renders them live, exactly as a browser would, using an isolated preview element. When you click Render PNG, that same preview node is captured pixel-for-pixel using the html-to-image library and turned into a downloadable PNG file, at 1x, 2x, or 3x resolution for crisp retina output.

This is useful for generating social cards, email-safe graphics, code snippet screenshots, UI mockups, or any other design you want to freeze as a static image. Everything happens entirely in your browser — your markup, styles, and the rendered image never leave your device or touch a server. Toggle a transparent background if you need a PNG with alpha instead of a solid fill, and use the width presets to control how wide the exported canvas is.
