## What it is
canvg is a JavaScript library that parses SVG files (from URL or text) and renders them onto HTML Canvas, including animation support. It can also be used to rasterize SVG images to canvas-based bitmaps.

## Use cases
- render svg files on html canvas
- rasterize svg to png in the browser
- display svg animations with canvas
- convert svg markup to canvas drawing
- render svg in node without a browser
- support svg in canvas-based export features

## When to choose
- you need to draw SVG content onto a canvas element
- you need to rasterize SVGs to bitmap images client-side
- you need SVG animation support rendered via canvas
- you need SVG rendering in Node.js without a DOM

## When to avoid
- you just need to display static SVGs in the DOM - use native <svg> or <img>
- you need full SVG spec compliance including filters and advanced features
- you need server-side SVG to PNG conversion with high fidelity - consider resvg or librsvg
