Modern PDFWASM-Accelerated PDF Engine

Create, parse, merge, and manipulate PDFs in every JavaScript runtime. ESM-only, one dependency, TypeScript-first.

Universal Runtime

Runs natively in Node.js 25+, Deno, Bun, Cloudflare Workers, and all modern browsers. One package, zero platform forks.

Optional WebAssembly modules for compression, image decoding, and font shaping — with pure-JS fallbacks that still outperform the competition.

Generate PDFs as a ReadableStream for low-memory server workloads. Stream directly to HTTP responses without buffering entire documents.

Pure ESM with zero side effects. Import only what you need — core bundle starts under 20 KB gzipped. No CommonJS baggage.

Written in TypeScript 6.0 with strict types, declaration maps, and full IntelliSense. Every API surface is precisely typed.

Generate archival-grade PDF/A-1b through PDF/A-3u documents for long-term preservation, regulatory compliance, and accessibility.

Head-to-head across 30 operations. Measured with Vitest bench on Node.js 25.7.
