How to Resize Image Before Upload in Laravel 11?

Hi, Dev

In this tutorial, I'll guide you through resizing images before uploading them in a Laravel 11 application using the Intervention/Image library

We'll leverage the Intervention/Image Composer package to handle image resizing within our Laravel project. First, we'll integrate the Intervention/Image-Laravel Composer package to seamlessly utilize the Intervention/Image library within Laravel. This library offers versatile functionalities such as image resizing and watermark addition.

For this demonstration, we'll begin by installing the Intervention/Image Composer package. Through methods like read() and resize(), Intervention/Image facilitates image resizing effortlessly. Our example involves crafting a straightforward form containing a file input field. Upon selecting an image, users will witness previews of both the original and thumbnail versions of the image.

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
