How to Resize Specific SKU Images in Magento 2 Using CSV

As we all know, Magento 2 comes standard with an image resize command. However, when we run the image resize command, it will resize all of the product images, which will take too long if the site has a larger catalog size, and in this situation, most developers will have to wait and spend too much time on the image resize process. As a solution, we've written this article to assist you in resizing specific SKU images using CSV.

Let's get started!!

Create the ImageResize.php file at the <Magento Root Folder Path>/pub/ and paste the below code.

saveCopyzoom_out_map
<?php

error_reporting(E_ALL);
ini_set('display_errors', 1);

use Magento\Framework\App\Bootstrap;
require dirname(__DIR__) . '/app/bootstrap.php';
$bootstrap = Bootstrap::create(BP,$_SERVER);
$objectManager = $bootstrap->getObjectManager();
$registry = $objectManager->get('Magento\Framework\Registry');
$state = $objectManager->get('Magento\Framework\App\State');
$state->setAreaCode('frontend');
$registry->register('isSecureArea',true);

$file = '/<Magento Root Folder Path>/pub/sku.csv';
$csvData = $objectManager->get('\Magento\Framework\File\Csv')->getData($file);

if(empty($argv[1]) || $argv[1]!= 'start'){
    echo 'Access Denied'."\n";exit;
}
echo 'Total Record: '.count($csvData)."\n";
foreach ($csvData as $row => $data) {
        if($row > 0){
            $sku = $data[0];
            try
            {
                $product = $objectManager->get('\Magento\Catalog\Model\ProductRepository')->get($sku);
                $resize = $objectManager->get('\Magento\MediaStorage\Service\ImageResize');

                if ($product->getData()) {
                    $images = $product->getMediaGalleryImages();
                    if($images){
                        foreach ($images as $key => $image) {
                            if($image['disabled'] == 0){
                                $resize->resizeFromImageName($image['file']);
                                echo 'Row:'.$row.'     '.$sku.'     '.$image['file'].'\n';
                            }
                       }
                      
                    }
                } 
            }
            catch(\Exception $e)
            {
                echo 'Row:'.$row.'     '.$sku.': is not available.'.'\n';
            }           
            
        }
    }
echo 'Done';
die();
?>

In above code you need to replace the <Magento Root Folder Path> path in $file variable with your actual path.

You must also prepare a CSV file with the column name SKU and add all of the product SKUs for which you wish to resize images.

Finally, we are done, To run this script you need to open your terminal and go to the /<Magento Root Folder Path>/pub/ path and run the below command.

saveCopyzoom_out_map
php ImageResize.php start

That's it!!

You'll see in the code that we've added a start parameter for security purposes. If this script is accidentally launched in a browser, it will halt execution immediately after the condition that we verified on code.
