So here i write step by step tutorial of resize image in Laravel. So just follow bellow step to create image example for your project.

Step 1: Install Laravel 6

In this step, if you haven't Laravel 6 Application setup then we have to get fresh Laravel 6 Application. So run bellow command and get clean fresh Laravel 6 Application.

Step 2: Install Intervention Image Package

In second step we will install intervention/image for resize image. this package through we can generate thumbnail image for our project. so first fire bellow command in your cmd or terminal:

return [
    ......
    $provides => [
        ......
        ......,
        'Intervention\Image\ImageServiceProvider'
    ],
    $aliases => [
        .....
        .....,
        'Image' => 'Intervention\Image\Facades\Image'
    ]
]

Step 3: Create Routes

In this step we will add routes and controller file so first add bellow route in your routes.php file.

routes/web.php

Route::get('resizeImage', 'ImageController@resizeImage');
Route::post('resizeImagePost', 'ImageController@resizeImagePost')->name('resizeImagePost');

Step 4: Create Controller File

Now require to create new ImageController for image uploading and resizeing image so first run bellow command :

php artisan make:controller ImageController

After this command you can find ImageController.php file in your app/Http/Controllers directory. open ImageController.php file and put bellow code in that file.

app/Http/Controllers/ImageController.php

<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;

use App\Http\Requests;

use Image;

class ImageController extends Controller

{
/**
 * Show the form for creating a new resource.
 *
 * @return \Illuminate\Http\Response
 */
public function resizeImage()
{
    return view('resizeImage');
}

/**
 * Show the form for creating a new resource.
 *
 * @return \Illuminate\Http\Response
 */
public function resizeImagePost(Request $request)
{
    $this-&gt;validate($request, [
        'title' =&gt; 'required',
        'image' =&gt; 'required|image|mimes:jpeg,png,jpg,gif,svg|max:2048',
    ]);

    $image = $request-&gt;file('image');
    $input['imagename'] = time().'.'.$image-&gt;extension();
 
    $destinationPath = public_path('/thumbnail');
    $img = Image::make($image-&gt;path());
    $img-&gt;resize(100, 100, function ($constraint) {
        $constraint-&gt;aspectRatio();
    })-&gt;save($destinationPath.'/'.$input['imagename']);

    $destinationPath = public_path('/images');
    $image-&gt;move($destinationPath, $input['imagename']);

    return back()
        -&gt;with('success','Image Upload successful')
        -&gt;with('imageName',$input['imagename']);
}

}

resources/views/resizeImage.blade.php

@extends(‘layouts.app’)
@section(‘content’)

<div class=“container”>

<h1>Resize Image Uploading Demo</h1>

@if (count($errors) > 0)

<div class=“alert alert-danger”>

<strong>Whoops!</strong> There were some problems with your input.<br><br>

<ul>

@foreach ($errors->all() as $error)

<li>{{ $error }}</li>

@endforeach

</ul>

</div>

@endif
@if ($message = Session::get(‘success’))

<div class=“alert alert-success alert-block”>

<button type=“button” class=“close” data-dismiss=“alert”>×</button>

<strong>{{ $message }}</strong>

</div>

<div class=“row”>

<div class=“col-md-4”>

<strong>Original Image:</strong>

<br/>

<img src=“/images/{{ Session::get(‘imageName’) }}” />

</div>

<div class=“col-md-4”>

<strong>Thumbnail Image:</strong>

</div>

</div>

@endif
{!! Form::open(array(‘route’ => ‘resizeImagePost’,‘enctype’ => ‘multipart/form-data’)) !!}

<div class=“row”>

<div class=“col-md-4”>

<br/>

{!! Form::text(‘title’, null,array(‘class’ => ‘form-control’,‘placeholder’=>‘Add Title’)) !!}

</div>

<div class=“col-md-12”>
