## What it is
resvg is a fast, portable SVG rendering library written entirely in safe Rust, usable as a Rust library, C library, or CLI application for converting static SVG files to PNG. It aims for full SVG 1.1 spec coverage with a ~1600-test regression suite and separates SVG parsing (usvg) from rendering.

## Use cases
- convert svg files to png
- render svg images server-side
- embed svg rendering in a rust application
- render svg thumbnails in a batch pipeline
- render svg in webassembly
- validate svg rendering correctness against a test suite
- build a custom svg renderer on top of a parsed svg tree

## When to choose
- you need correct, spec-compliant rendering of static SVG without a browser
- memory safety matters - it's pure Rust with almost no unsafe code
- you need a small, dependency-free portable binary including WASM support
- you want to preprocess/simplify SVG (usvg) and render it with your own 2D engine

## When to avoid
- you need animated or scriptable (dynamic) SVG support
- you need a full browser-grade SVG engine with CSS interactions
- you need SVG editing or authoring rather than rendering

## Facets
- artifact type: library
- maturity: stable
- function: image-processing, graphics, parser, cli
- domain: graphics, image-processing, web-development, developer-tools
- platform: cross-platform, rust, cli, wasm
- tags: svg, svg-to-png, rasterization, usvg, memory-safe, no-unsafe
