I was looking online when I found ray.so, an small online web-app which turns code into images. It supports light mode, dark mode, and four colour themes, and syntax highlights code, adds gradients, and allows you to download it as an image. It might not look useful, but it looks like it can be very useful for using on websites like this one.
You can find ray.so at https://ray.so, but please note that I do not own or maintain it.
I hope this is useful,
