## What it is
A high-performance SVG renderer and toolkit for Node.js, Deno, and browsers, built on the Rust resvg library via napi-rs with a WebAssembly backend. It converts SVG to PNG with cropping, scaling, custom fonts, and simplified SVG output.

## Use cases
- convert svg to png in nodejs
- render svg with custom fonts server-side
- generate png thumbnails from svg files
- render svg in the browser with wasm
- crop and scale svg images programmatically
- simplify svg shapes to paths
- get svg dimensions and bounding box

## When to choose
- you need fast, correct SVG-to-PNG rendering in Node.js, Deno, or the browser
- you need custom font support in SVG text rendering
- you want a zero-dependency native addon without node-gyp builds

## When to avoid
- you need to rasterize SVG to formats other than PNG
- you work outside the JavaScript ecosystem and can use resvg directly
- you need full SVG animation support

## Facets
- artifact type: library
- maturity: active
- function: image-processing, graphics
- domain: web-development, graphics, developer-tools
- platform: rust, wasm, cross-platform
- tags: svg-rendering, svg-to-png, napi-rs, native-addon, font-rendering, nodejs, deno
