Sure, I could just manually run svgo on any SVGs I wanted to use, but what I really wanted was a way to optimize SVGs at build time because: They’re all just plain black circles, but the third one takes up 20x less space than the first one. Here’s how all 3 versions of our circle SVG look when rendered: image/svg+xml The Inkscape SVG version: 2 KB This was much more reasonable - using Inkscape’s default settings, the Optimized SVG markup for our circle is: That’s 2 KB of markup for basically nothing.Įventually (read: after an embarrassingly long time 🤷), I figured out that Inkscape had an Optimized SVG output format.
