## What it is
html2canvas is a JavaScript library that renders webpages or DOM elements as canvas images entirely in the browser, without server-side rendering. It rebuilds a visual representation by reading the DOM and applied CSS styles, so output may not be pixel-perfect and some CSS properties are unsupported.

## Use cases
- capture a screenshot of a webpage in the browser
- export a DOM element as a PNG image
- let users download a snapshot of a report or card
- render part of a page to canvas for sharing
- generate client-side page images without a server

## When to choose
- you need client-side page or element capture with no server rendering
- you want a lightweight (~45kb gzipped) MIT-licensed library
- your content is same-origin and uses well-supported CSS

## When to avoid
- you need pixel-perfect or full CSS fidelity
- you need to capture cross-origin content without a proxy
- you want to run it in Node.js (browser-only)
- you need production-grade stability for complex layouts

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