@wasm-zoo/ghostscript

Unofficial WASM Zoo distribution of the Ghostscript gs CLI for browsers. This package is backed by Ghostscript 10.08.0, Zoo builder 0.7.2, and the reviewed browser-full Release asset.

Install

npm install @wasm-zoo/ghostscript

Use

import { load } from "@wasm-zoo/ghostscript";

const gs = await load();
try {
  const result = await gs.exec([
    "-dSAFER", "-dBATCH", "-dNOPAUSE",
    "-sDEVICE=png16m", "-r150",
    "-sOutputFile=/out/page.png", "/input.pdf"
  ], {
    files: [{ name: "/input.pdf", data: pdfBytes }],
    dirs: ["/out"],
    outputs: ["/out/page.png"]
  });
  console.log(result.files[0]);
} finally {
  gs.dispose();
}

The default entry imports the reviewed browser wrapper and uses static new URL(..., import.meta.url) references so modern bundlers can emit gs-core.js, gs-core.wasm. For manual/self-hosted deployments use @wasm-zoo/ghostscript/self-hosted and the Consumer API v1 baseUrl contract.

No SharedArrayBuffer or cross-origin isolation is required. Each gs command runs in an isolated Web Worker with MEMFS. The bundled Ghostscript WebAssembly binary is AGPL-3.0-or-later; review the bundled LICENSE-Ghostscript.txt and THIRD-PARTY-LICENSES/ notices before redistribution.
