## What it is
A JavaScript library that renders HTML into the browser's canvas element by embedding it in an SVG foreignObject and drawing it via drawImage. It inlines external images, fonts, and stylesheets as data URIs to work around SVG resource restrictions.

## Use cases
- render html to canvas in the browser
- generate a screenshot of html content client-side
- convert dom content to an image without a server
- export html snippets as canvas graphics
- draw a webpage into a canvas element

## When to choose
- you need client-side HTML-to-image rendering with no backend
- your content is same-origin or CORS-enabled
- you target modern Firefox, Chrome, or Safari

## When to avoid
- you need Internet Explorer support
- you must render cross-origin resources without CORS
- you need pixel-perfect full-page screenshots of arbitrary websites

## Facets
- artifact type: library
- maturity: maintenance
- function: image-processing, graphics
- domain: web-development, frontend
- platform: browser
- tags: html-to-canvas, svg-foreignobject, screenshot, client-side-rendering, canvas, javascript
