What is optipng-bin?

The optipng-bin package provides a Node.js wrapper for the OptiPNG image optimization tool. It allows you to optimize PNG images by reducing their file size without losing quality. This can be particularly useful for web developers looking to improve page load times by minimizing image sizes.

What are optipng-bin's main functionalities?

Optimize a single PNG image

This feature allows you to optimize a single PNG image using the highest optimization level (-o7). The code sample demonstrates how to use the optipng-bin package to optimize 'input.png' and log a message upon completion.

const execFile = require('child_process').execFile;
const optipng = require('optipng-bin');

execFile(optipng, ['-o7', 'input.png'], (err) => {
  if (err) {
    throw err;
  }
  console.log('Image optimized');
});

Optimize multiple PNG images

This feature allows you to optimize multiple PNG images in a batch. The code sample demonstrates how to loop through an array of image filenames and optimize each one using the optipng-bin package.

const execFile = require('child_process').execFile;
const optipng = require('optipng-bin');

const images = ['image1.png', 'image2.png', 'image3.png'];

images.forEach((image) => {
  execFile(optipng, ['-o7', image], (err) => {
    if (err) {
      throw err;
    }
    console.log(`${image} optimized`);
  });
});

Custom optimization level

This feature allows you to specify a custom optimization level for the PNG image. The code sample demonstrates how to use the optipng-bin package to optimize 'input.png' with an optimization level of 2.

const execFile = require('child_process').execFile;
const optipng = require('optipng-bin');

execFile(optipng, ['-o2', 'input.png'], (err) => {
  if (err) {
    throw err;
  }
  console.log('Image optimized with custom level');
});
