optipng-neo

A modern fork of optipng‑bin – a wrapper for OptiPNG that makes it available as a local dependency without global installation. OptiPNG is an advanced PNG optimizer that recompresses image files to a smaller size without losing any information.

Why optipng‑neo? This package continues the development of the original optipng‑bin with a focus on modern stack (ESM, TypeScript, node:child_process), improved documentation, and production readiness. Fully compatible with existing workflows while bringing freshness and reliability.

🚀 Install

npm install optipng-neo

Or via pnpm / yarn:

pnpm add optipng-neo

📦 Usage

Programmatic API (ESM)

import { execFile } from "node:child_process";
import { join } from "node:path";
import { cwd } from "node:process";

import { optipng } from "optipng-neo";

const __dirname = cwd();
const file = join(__dirname, "test", "input.png");
const out = join(__dirname, "test", "output.png");

execFile(optipng, ["-out", out, file], (error) => {
  if (error) throw error;
  console.log("✅ Image optimized!");
});

CLI (global install)

npm install --global optipng-neo

After installation, the optipng command becomes available in your terminal:

optipng --help

Example optimization:

optipng -o7 input.png -out output.png

✨ What's inside?

• 🔗 Full compatibility with all flags and parameters of the original OptiPNG.
• 🌍 Automatic binary download for your platform (Windows, macOS, Linux) – no manual downloads needed.
• ⚡ Pure ESM + TypeScript – modular architecture ready for modern environments.
• 📦 No global installation required – OptiPNG works as a local dependency, ensuring reproducible builds.
• 📏 Lightweight dependency – only the necessary files, no extra bloat in node_modules.
• 🛠️ Native API – uses node:child_process, avoiding legacy solutions.

🔧 Who is it for?

• Frontend developers who want to integrate PNG optimization into their build pipelines (Webpack, Vite, Gulp, Rollup).
• Teams where reproducibility matters – the binary is pinned inside node_modules, eliminating environment discrepancies.
• CI/CD engineers tired of global dependency issues on build servers.
• Any project that needs reliable, self‑contained PNG optimization without extra complexity.
