simple-webp-converter

A simple Node.js library for converting PNG and JPG images to WebP format using webp-converter.

Features

• Convert PNG and JPG images to WebP
• CLI tool for easy integration into build scripts
• Programmatic API for custom workflows
• Configurable source patterns using glob

Installation

npm install simple-webp-converter --save-dev

Usage

CLI Usage

Add to your package.json scripts:

{
  "scripts": {
    "webp": "simple-webp-converter"
  }
}

Run the conversion:

npm run webp

This will create WebP copies of all PNG and JPG files in the project (excluding node_modules).

Configuration

Configure options in package.json under the "simple-webp-converter" key:

{
  "simple-webp-converter": {
    "src": "src/**/*.{png,jpg}",
    "quality": 90
  }
}

With this config, only images under the /src folder will be converted with 90% quality.

Programmatic Usage

const simpleWebpConverter = require("simple-webp-converter");

// Use default settings (converts **/*.{png,jpg} at quality 80)
simpleWebpConverter();

// Use custom source pattern and quality
simpleWebpConverter({
  src: "assets/**/*.{png,jpg}",
  quality: 90
});

Options

• src (string): Glob pattern to match source images. Default: "**/*.{png,jpg}"
• quality (number): WebP quality (0-100). Default: 80

Notes

• Output files are created in the same directory as the source files with .webp extension.
• Quality ranges from 0 (worst) to 100 (best).
• Requires webp-converter which depends on WebP tools being installed on the system.
