        ......,

routes/web.php

<?php
  
use Illuminate\Support\Facades\Route;
use App\Http\Controllers\ImageResizeController;
  
/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/
  
Route::get('resizeImage', [ImageResizeController::class, 'resizeImage']);
Route::post('resizeImagePost', [ImageResizeController::class, 'resizeImagePost'])->name('resizeImagePost');

Step 4: Add Controller

php artisan make:controller ImageResizeController

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

app/Http/Controllers/ImageResizeController.php

<?php
  
namespace App\Http\Controllers;
   
use Illuminate\Http\Request;
use App\Http\Requests;
use Image;
  
class ImageResizeController 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)
    {
        $this->validate($request, [
            'title' => 'required',
            'image' => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:2048',
        ]);
  
        $image = $request->file('image');
        $input['imagename'] = time().'.'.$image->extension();
     
        $destinationPath = public_path('/thumbnail');
        $img = Image::make($image->path());
        $img->resize(100, 100, function ($constraint) {
            $constraint->aspectRatio();
        })->save($destinationPath.'/'.$input['imagename']);
   
        $destinationPath = public_path('/images');
        $image->move($destinationPath, $input['imagename']);
   
        return back()
            ->with('success','Image Upload successful')
            ->with('imageName',$input['imagename']);
    }
   
}

Step 5: Add Blade File

In this last step we will create resizeImage.blade.php file for photo upload form and manage error message and also success message. So first create resizeImage.blade.php file and put bellow code:

resources/views/resizeImage.blade.php
