How do they automatically generate these pictures?

Question

JavaScript

I noticed an interesting feature on one site. Articles published by users automatically receive a generated image

After digging into their code, I saw that they do it using Cloudinary. Is it possible to make a picture of the same quality using some open source tools, such as GraphicsMagick or their analogues, preferably with a module for Node)?

Answer 1

so dozens or even thousands of ways, on github by searching html to jpg and choosing the language you need, you can still make svg and convert it to jpg
