Image-to-AVIF Converter

A simple and efficient Node.js script to convert images (PNG, JPG, JPEG, and WEBP) into the AVIF format with optimized compression and high-quality output. This project utilizes the sharp library for image processing.

Features

• Supports PNG, JPG, JPEG, and WEBP formats.
• Converts images to AVIF format with adjustable quality.
• Processes multiple images in parallel for faster conversions.
• Automatically creates the output directory if it doesn’t exist.
• Logs detailed conversion progress and errors.

Prerequisites

• Node.js

Installation

1. Clone the repository or download the source code.
2. Navigate to the project directory:

   cd image-to-avif

3. Install the dependencies:

   npm install

Usage

1. Add images to the src/images directory.
2. Run the script:

   npm start

3. The converted AVIF images will be saved in the src/output directory.

Configuration

• Quality Setting: The AVIF quality can be adjusted in src/index.js by modifying the quality variable:

  const quality = 50; // Adjust quality (0-100)

• Parallel Processing: The script uses the number of available CPU cores for optimal performance. You can override this by changing the maxThreads variable:

  const maxThreads = 4; // Example: limit to 4 threads

Example Output

Input:

src/images/
├── default.png

Output:

src/output/
├── default.avif
