fyi/ it ignores to always use `primitive`

& output into stdout does not work as descr. @ https://github.com/axe312ger/sqip/#output

Yes, SVGO expects a svg to be input. If you pass an JPG, it does not know what to do with it. You first need to use a plugin that transforms pixels into vectors, like the pixelator plugin or the primitive plugin. Then you can use the svgo plugin to minimize the SVG data

[xerc]

yea ; but sqip -i input.jpg is possible & therefore its a bit confusing may consider primitive as fallback if potrace | pixels are not used

I see your point, but when you don't pass any plugins, it runs the default set of plugins.

We might make it more clear by outputting which plugins are used when running the command
