Resize Product Images Programmatically in Magento 2 • Devhooks

In this article we'll discuss how to resize product images programmatically in Magento 2. As we know resizing product images programmatically in Magento 2 entails making use of Magento's built-in functions and features. You can accomplish this by writing your own script or module. The steps for resizing product photos programmatically are listed below.

Step 1: Create a Custom Module (if needed)

If you don't have a custom module already, you need to create one module. If you already have a module then go with that. If you are new to Magento then check our another article How To Create a Magento 2 Module.

Step 2: Create Class or Function

Within your custom module, create a script or function that retrieves the product image and resizes it.

In this atricle will create a helper class Data.php file at app/code/Devhooks/ModuleName/Helper and paste the below code.

saveCopyzoom_out_map<?php
namespace Devhooks\ModuleName\Helper;

use Magento\Catalog\Helper\Image;
use Magento\Catalog\Model\ProductRepository;
use Magento\Framework\App\Helper\AbstractHelper;
use Magento\Framework\App\Helper\Context;

class Data extends AbstractHelper
{
    private ProductRepository $productRepository;
    private Image $productImage;

    /**
     * @param Context $context
     * @param ProductRepository $productRepository
     * @param Image $productImage
     */
    public function __construct(
        Context           $context,
        ProductRepository $productRepository,
        Image             $productImage
    ) {
        parent::__construct($context);
        $this->productRepository = $productRepository;
        $this->productImage = $productImage;
    }

    /**
     * @param int $productId
     * @param string $imageType
     * @param int $imagewidth
     * @param int $imageheight
     * @return string
     * @throws \Magento\Framework\Exception\NoSuchEntityException
     */
    public function getResizeProductImage(
        $productId,
        $imageType = 'thumbnail',
        $imagewidth = 100,
        $imageheight = 100
    ) {
        $product = $this->productRepository->getById($productId);
        $imageUrl = $this->productImage->init($product, $imageType);
        $imageUrl->setImageFile($product->getImage());
        $imageUrl->resize($imagewidth, $imageheight)->getUrl();
        return $imageUrl;
    }
}

In the above code, we have created a helper class with getResizeProductImage method. You can injecte the helper class whereever you need and use the getResizeProductImage method and pass the required parameters.

Step 3: Open Command line in folder root of magento and run commands for create new customer attribute programmatically.

saveCopyzoom_out_mapphp bin/magento setup:upgrade

php bin/magento cache:clean

Bingo!! we are done.
