Skia Canvas 2.0: A Browserless Canvas Environment for Node

Based on Google’s Skia graphics engine and offers end results similar to Chrome’s own canvas system. It’s GPU accelerated and can render images, paths, fonts, shapes, and (almost) everything you’d expect. v2.0 adds support for WOFF/WOFF2 fonts, WEBP exporting, and more.
