How to Resize Specific Product Image using Command Line in Magento 2?

Hello Magento Friends,

With this Magento 2 tutorial, I will provide the solution for Resizing Specific Product Image using Command Line in Magento 2.

Product images attract the user’s attention. If they are not displayed properly, it will create a bad user experience. Hence, to make sure the product images fit correctly and display properly, you may need to resize them.

Magento 2 provides an image resize command which will resize all the product images at once. If you want to resize only a specific product image, the below steps will help you to accomplish it.

Steps to Resize Specific Product Image using Command Line in Magento 2:

Step 1: Create a di.xml file at the given path

app/code/Vendor/Extension/etc/di.xml

Now add the code as follows

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <type name="Magento\Framework\Console\CommandListInterface">
        <arguments>
            <argument name="commands" xsi:type="array">
                <item name="imagesResizeCommand" xsi:type="object">
                    Vendor\Extension\Console\Command\ImagesResizeCommand
                </item>
            </argument>
        </arguments>
    </type>
    <type name="Vendor\Extension\Console\Command\ImagesResizeCommand">
        <arguments>
            <argument name="imageResizeScheduler" xsi:type="object">
                Magento\MediaStorage\Service\ImageResizeScheduler\Proxy
            </argument>
        </arguments>
    </type>
</config>

Step 2: Now, you need to create the ImagesResizeCommand.php file at the below path

app/code/Vendor/Extension/Console/Command/ImagesResizeCommand.php

Then add the following code

<?php

declare(strict_types=1);

namespace Vendor\Extension\Console\Command;

        ->columns(

        );
        return (int) $this->resourceConnection->getConnection()->fetchOne($select);
    }
}

Step 3: After deploying this module, you need to execute this below command to resize a specific product image.

php bin/magento test:product:resize --product_id=1

Here, test:product:resize is custom command and product_id is an argument where you need to pass your product id.

Conclusion:

Using the above method, you can easily resize specific product images in Magento 2 via the command line. Moreover, Image Optimizer Extension for Magento 2 helps to reduce the image size without losing its quality.

Happy Coding!
