Questions regarding pdf to image conversion with Node JS - node.js

Question

The plan is to create a pdf file (that only consists of a single page) then the user chooses whether to download as PDF or image. I have already written the code for generating the PDF and it is working fine as of now. The problem now is how to convert this to image. Is it possible to convert files without installing stuff like Ghostscript etc?
I am a complete noob, advice is greatly appreciated. (Recommendations on which libraries to use would also be helpful)
Code for generating the PDF
import PDFDocument from "pdfkit";
static async medicalPrescription(req, res) {
// Some code for generating the PDF contents...
filename = encodeURIComponent(filename) + '.pdf'
res.setHeader('Content-disposition', 'attachment; filename="' + filename + '"')
res.setHeader('Content-type', 'application/pdf')
const content = req.body.content
doc.y = 300
doc.text(content, 50, 50)
doc.pipe(res)
doc.end()
}
The client then receives the generated file and opens it in another tab.
React file that sends the request and opens the response
const handleSubmit = async (e) => {
// Some code for sending the pdf content from the user
fetch("http://localhost:5050/generate-rx", {
method: 'POST',
headers: {
'Content-Type': 'application/json',
},
body: parsed
})
.then(async res => {
if (res.status === 200) {
const blob = await res.blob();
const file = new Blob(
[blob],
{type: 'application/pdf'}
);
const fileURL = URL.createObjectURL(file);
window.open(fileURL);
}
})
}

You can use pdf2pic. It can convert pdf to image.
import { fromPath } from "pdf2pic";
const options = {
density: 100,
saveFilename: "untitled",
savePath: "./images",
format: "png",
width: 600,
height: 600
};
const storeAsImage = fromPath("/path/to/pdf/sample.pdf", options);
const pageToConvertAsImage = 1;
storeAsImage(pageToConvertAsImage).then((resolve) => {
console.log("Page 1 is now converted as image");
console.log(resolve); // send resolve to user
});
