A while back I built a cli tool and gradle plugin that can bidirectionally convert svgs and vector drawables. It also shrinks them kinda like svgo. It could support image vector and other formats like vector pdf with not a lot of work (probably). It would only require adding logic to read and write those formats to and from the internal representation. https://github.com/jzbrooks/vgo

It's definitely a good one, especially for frameworks building docs and sites with Gradle. CC @Laura Kassovic who might be usifng this plugn 🙂
