What is PDFium?

PDFium is an open-source PDF rendering engine originally developed by Foxit Software and later released as open source by Google. Written in C++, it's the same engine that powers PDF viewing in Chrome and numerous other applications. This package brings native-quality PDF capabilities to the browser through WebAssembly, without requiring any server-side processing.

Features

- High-fidelity rendering of PDF pages
- Text extraction and search
- Form filling and manipulation
- Annotation support
- Digital signature verification
- PDF modification and creation

Installation

``bash


npm

`javascript
import { init, WrappedPdfiumModule } from '@embedpdf/pdfium';

const pdfiumWasm =
'https://cdn.jsdelivr.net/npm/@embedpdf/pdfium/dist/pdfium.wasm';

let pdfiumInstance = null;

async function initializePdfium() {
if (pdfiumInstance) return pdfiumInstance;

const response = await fetch(pdfiumWasm);
const wasmBinary = await response.arrayBuffer();
pdfiumInstance = await init({ wasmBinary });

// Initialize the PDFium extension library
// This is required before performing any PDF operations
pdfiumInstance.PDFiumExt_Init();

return pdfiumInstance;
}

// Usage
