PDFluent for WASM / JavaScript

One command. The package is on npm today.

Open a PDF, print the page count. The example below is the smallest useful program — copy, paste, run.

import init, { PdfDocument } from '@pdfluent/sdk-wasm';

await init();
const bytes = new Uint8Array(await file.arrayBuffer());
const doc = PdfDocument.open(bytes);
console.log(`${doc.pageCount()} pages`);

• In-browser PDF processing — no server required
• Privacy-sensitive client-side workflows
• SaaS demos and document previews

This list is honest, not exhaustive. The site-wide list lives at Known limitations.

• Public beta — APIs may shift before 1.0.
• Threaded execution requires the page to be served with COOP/COEP headers.
• Bundle size: the WASM binary is several MB. Pre-fetch and cache aggressively.
• XFA rendering fidelity is improving alongside the Rust core.

PDFluent ships with a 30-day trial built in. Every paid plan includes a perpetual-fallback licence — your build keeps working at the version you licensed, indefinitely. Details on the licensing page.
