Two of `pdf-lib`'s distinguishing features are: 1. Supporting modification (editing) of existing documents. 2. Working in all JavaScript environments - not just in Node or the Browser. There are [other](#prior-art) good open source JavaScript PDF libraries available. However, most of them can only _create_ documents, they cannot _modify_ existing ones. And many of them only work in particular environments. ## Usage Examples ### Create Document _This example produces [this PDF](assets/pdfs/examples/create_document.pdf)._ [Try the JSFiddle demo](https://jsfiddle.net/Hopding/rxwsc8f5/13/) ```js import { PDFDocument, StandardFonts, rgb } from 'pdf-lib' // Create a new PDFDocument const pdfDoc = await PDFDocument.create() // Embed the Times Roman font const timesRomanFont = await pdfDoc.embedFont(StandardFonts.TimesRoman) // Add a blank page to the document const page = pdfDoc.addPage() // Get the width and height of the page const { width, height } = page.getSize() // Draw a string of text toward the top of the page const fontSize = 30 page.drawText('Creating PDFs in JavaScript is awesome!', { x: 50, y: height - 4 * fontSize, size: fontSize, font: timesRomanFont, color: rgb(0, 0.53, 0.71), }) // Serialize the PDFDocument to bytes (a Uint8Array) const pdfBytes = await pdfDoc.save() // For example, `pdfBytes` can be: // • Written to a file in Node // • Downloaded from the browser // • Rendered in an
