PDF to Image Conversion in Node.js Apps

The open source Node-PDF-Image Library has provided complete supports for converting PDF documents to image file formats inside Node.js applications. It allows converting each page of a PDF document into an image with just a couple of lines of code. It supports multiple image formats, including PNG and JPEG, which allows flexibility depending on the needs of your project. Here is an example that shows how software developers can convert PDF to Image formats using JavaScript code.

How to Convert PDF to Image Format inside Node.js App?

const PDFImage = require("node-pdf-image").PDFImage;

const pdfPath = "/path/to/your/document.pdf";  // Specify the PDF path
const pdfImage = new PDFImage(pdfPath);

pdfImage.convertPage(0).then(function(imagePath) {
    console.log("Page 0 converted to:", imagePath);
});

Handling Multi-Page PDFs in Node.js

Node-PDF-Image is particularly useful when dealing with multi-page PDF documents. It provides methods to handle each page individually, allowing you to convert an entire PDF or just selected pages into images inside Node.js applications. The following basic example converts the first page (0-indexed) of the PDF into a PNG image. The convertPage() method converts the specified page and returns a promise with the path to the generated image.

How to Convert a Specified PDF Page to a PNG Image in Node.js?

const PDFImage = require("node-pdf-image").PDFImage;

const pdfImage = new PDFImage("/path/to/sample.pdf");

pdfImage.convertPage(0).then(function(imagePath) {
    console.log("Page 0 is now converted to image and stored at:", imagePath);
});

High-Resolution Output in Node.js

In scenarios where high-quality images are essential, the open source Node-PDF-Image library allows software developers to control the resolution of the output images. Whether developers need a thumbnail preview or a detailed, high-resolution image for printing, Node-PDF-Image provides the flexibility to adjust the image resolution to meet specific application requirements.
