Convert PDFs to Images in Node.js
With PSPDFKit for Node.js, you can render independent pages of a PDF document and save them as images. If a document contains any annotations, they’ll be rendered over the page background.
Rendering and Exporting a Specific Page as an Image
The following example saves a single page from a document as a PNG file:
import fs from 'node:fs'; import { load } from '@pspdfkit/nodejs'; const doc = fs.readFileSync('source.pdf'); const instance = await load({ document: doc }); const pageWidth = instance.getDocumentInfo().pages[0].width; const result = await instance.renderPage(0, { width: pageWidth }); fs.writeFileSync('page.png', Buffer.from(result)); await instance.close();
By default, the image will be exported as PNG. You can choose to export it to WebP instead by modifying the call to instance.renderPage()
as follows:
const result = await instance.renderPage(0, { width: pageWidth }, 'webp');
