So you want to split your SVGs? Here's a page that will do that for you
I posted ages ago about a little script to split a large SVG file into 15kb chunks.
At the time someone asked about a web version, which after a couple of afternoons with Gemini (and a couple of Python-related dead ends) I've got a page that works
This is for anyone who wants to get their artwork into the Livery editor in GT7.
Bear in mind this is the earliest release (I literally got this together on my lunchbreak) but I'd love to get your feedback.
I'm also working on a longer-form guide to creating and uploading SVGs, but for now please take https://cianhan.github.io/svgsplit/ for a spin around the block!
