Performance Optimization – webP

In an e-commerce website, images play a crucial role. To maintain image quality while optimizing performance, the implementation of a modern image format such as WebP is recommended.

WebP, developed by Google, supports both lossless and lossy compression for web images. It offers smaller file sizes compared to popular formats like JPEG and PNG, without compromising image quality.

Integrating WebP into your website can significantly enhance performance by reducing image sizes. This results in faster page load times and improved user experience.

Below is a simplified PHP code snippet that converts a JPG image to WebP:

<?php
// Specify the path to the original image file
$originalImagePath = 'webkul.jpg';

// Specify the path where you want to save the WebP image
$webpImagePath = 'webkul.webp';

// Load the original image using GD library
$originalImage = imagecreatefromjpeg($originalImagePath);

// Create a blank canvas for the WebP image
$webpImage = imagecreatetruecolor(
    imagesx($originalImage),
    imagesy($originalImage)
);

// Enable alpha blending on the WebP image
imagealphablending($webpImage, true);

// Copy the original image onto the WebP canvas
imagecopy(
    $webpImage,
    $originalImage,
    0,
    0,
    0,
    0,
    imagesx($originalImage),
    imagesy($originalImage)
);

// Save the WebP image
imagewebp(
    $webpImage,
    $webpImagePath
);

// destroy the image resources
imagedestroy($originalImage);
imagedestroy($webpImage);

echo 'Image converted to WebP format!';

Let’s just see the original image quality and size then we will check the converted image

As evident, the image size has been halved without any compromise in quality.

By converting all images to WebP format, you can improve your website’s performance. This format reduces file sizes while maintaining image quality.
