Laravel 11 Resize Image Before Upload Example

In this post, I will show you how to resize image before upload using intervention/image in laravel 11 application.

We will use the Intervention/Image Composer package to resize images in Laravel. We will install the Intervention/Image-Laravel Composer package to utilize the Intervention/Image library in Laravel. The Intervention/Image library provides several methods like resize and add watermark to images.

In this example, we will install the Intervention/Image Composer package. Intervention/Image provides methods to resize images using the `read()` and `resize()` methods. We will create a simple form with the file input field. You can choose an image, and then you will see a preview of the original and thumbnail images.

Step for How to Resize Image in Laravel 11?

• Step 1: Install Laravel 11
• Step 2: Install Intervention Image Package
• Step 3: Create Routes
• Step 4: Create Controller File
• Step 5: View File and Create Upload directory
• Run Laravel App

So, let's follow the below steps to generate a thumbnail image in the Laravel 11 application.

Step 1: Install Laravel 11

This step is not required; however, if you have not created the Laravel app, then you may go ahead and execute the below command:

composer create-project laravel/laravel example-app

Step 2: Install Intervention Image Package

In the second step, we will install intervention/image-laravel for resizing images. This package allows us to generate thumbnail images for our project. So, first, fire the command below in your CMD or terminal:

composer require intervention/image-laravel

Step 3: Create Routes

In this step, we will add routes and a controller file. So first, add the below route in your routes.php file.

routes/web.php

<?php
  
use Illuminate\Support\Facades\Route;
  
use App\Http\Controllers\ImageController;
  
Route::get('image-upload', [ImageController::class, 'index']);
Route::post('image-upload', [ImageController::class, 'store'])->name('image.store');

Step 4: Create Controller File

Now, it is required to create a new ImageController for image upload and resizing. So, first, run the command below:

php artisan make:controller ImageController

After this command, you can find the ImageController.php file in your app/Http/Controllers directory. Open ImageController.php file and put below code in that file.

Make sure you have created "images" and "thumbnail" (inside the images folder) folder in the public folder.

app/Http/Controllers/ImageController.php

<?php
  
namespace App\Http\Controllers;
  
use Illuminate\Http\Request;
use Illuminate\View\View;
use Illuminate\Http\RedirectResponse;
use Intervention\Image\Laravel\Facades\Image;
  
class ImageController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index(): View
    {
        return view('imageUpload');
    }
        
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request): RedirectResponse
    {
        $request->validate([
            'image' => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:2048',
        ]);
   
        $image = $request->file('image');
        $imageName = time().'.'.$image->extension();
       
        $destinationPathThumbnail = public_path('images/thumbnail');
        $img = Image::read($image->path());
        $img->resize(100, 100, function ($constraint) {
            $constraint->aspectRatio();
        })->save($destinationPathThumbnail.'/'.$imageName);
     
        $destinationPath = public_path('/images');
        $image->move($destinationPath, $imageName);
     
        return back()->with('success', 'Image Uploaded successfully!')
                     ->with('imageName', $imageName);
    }
}

Step 5: View File and Create Upload directory

Okay, in this last step, we will create the imageUpload.blade.php file for the photo upload form and manage error messages and also success messages. So first, create the imageUpload.blade.php file and put the code below:

resources/views/imageUpload.blade.php
