How can I edit a PDF using Puppeteer?

How can I edit a PDF using Puppeteer?

You can use Puppeteer to manipulate PDFs by generating a new PDF from HTML or modifying existing PDFs with libraries like pdf-lib.

Can you show me a code example for editing a PDF?

Sure! Here's a simple example:

const { PDFDocument } = require('pdf-lib');

async function editPdf() {
    const existingPdfBytes = await fetch('path/to/your.pdf').then(res => res.arrayBuffer());
    const pdfDoc = await PDFDocument.load(existingPdfBytes);
    const page = pdfDoc.getPage(0);
    page.drawText('Hello, World!', { x: 50, y: 700 });
    const pdfBytes = await pdfDoc.save();
    // Save or return the modified PDF
}

What libraries do I need to use with Puppeteer for PDF editing?

You might want to use libraries like pdf-lib for editing PDFs, and Puppeteer for generating PDFs from HTML.

Is it possible to merge multiple PDFs using Puppeteer?

Yes, you can merge PDFs using pdf-lib along with Puppeteer. Load the PDFs you want to merge and then combine them into a single document.
