How to Compress and Optimize Image before Uploading in Laravel 8
Since performance is by and astronomically immense the holy grail of software development, implements abound for building expeditious software, eminently those for optimizing online media, most of which are images and videos. Optimization in this context betokens downsizing the media files but maintaining a copacetic level of visual quality for distribution. The more minute those files are, the more expeditious your website loads.
This article shows you how to optimize images in Laravel.
Set Up a Laravel Project
Install Composer and PHP on your development or production machine and then run this command:
composer create-project --prefer-dist laravel/laravel performanceGo to the performance directory and rename the env.example file to .env.
Run the project with the command php artisan serve.
Your Laravel project is now up and running.
Set Up Cloudinary’s Laravel SDK
With Cloudinary, you can efficiently optimize media assets—regardless of programming language. One reason is that, by default, Cloudinary automatically performs certain optimization steps on all transformed images. Plus, its integrated, fast-delivery capability through content delivery networks (CDNs) ensures that your images are seamlessly displayed on your viewers’ devices.
To enable file uploads and optimization with Cloudinary:
Sign up for a free Cloudinary account, log in, and note your cloud name and API keys from the dashboard.
Install Cloudinary’s Laravel SDK:
composer require cloudinary-labs/cloudinary-laravelImportant: Be sure to follow the steps in the #Installation section. Publish the configuration file and add your Cloudinary credentials to the .env file of your app.
Set Up the Mechanics for File Uploads
Create a file-upload controller (FileUpload Controller) in your project:
php artisan make:controller FileUploadControllerOpen the FileUploadController.php file and add a method for displaying the upload form:
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
class FileUploadController extends Controller
{
public function showUploadForm()
{
return view('upload');
}
}Create an upload.blade.php file in the resources/views directory and populate the file with the code below:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>Laravel File Upload</title>
<!-- Fonts -->

html, body {

}
.full-height {

Laravel File Upload
</div>
@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>
@endif
<div class="links">
<form action="/upload" method="POST" enctype="multipart/form-data">

<div class="row">
<div class="col-md-6">

<button type="submit" class="btn btn-success">Upload a File</button>
</div>
</div>
</form>
</div>
</div>
</div>
</body>
</html>On a successful upload, the code above displays the form along with a confirmation message. Concurrently, the code posts the form data to an /upload route in the routes/web.php file.
Note: You'll see the related code later in this post.
Go to the routes/web.php directory and add two routes: one to display the form and the other to process the file upload:
<?php
Route::get('/upload', 'FileUploadController@showUploadForm');
Route::post('/upload', 'FileUploadController@storeUploads');Now reload the app and go to the /upload route. This page is then displayed:
Compress and Resize Images On Upload
Create an upload method in the FileUploadController.php file to ensure that compression and resizing of user-uploaded images occur by default on upload.
The code below resizes an image to 100 pixels in both width and height:
public function upload(Request $request)
{
$resizedImage = cloudinary()->upload($request->file('image')->getRealPath(), [
'folder' => 'uploads',
'transformation' => [
'width' => 100,
'height' => 100
]
])->getSecurePath();
dd($resizedImage);
}The code below resizes an image through smart cropping:
public function upload(Request $request)
{
$resizedImage = cloudinary()->upload($request->file('image')->getRealPath(), [
'folder' => 'uploads',
'transformation' => [
'width' => 100,
'height' => 100,
‘crop’ => ‘limit’
]
])->getSecurePath();
dd($resizedImage);
}The code below, slated for images with people, focuses on those people through cropping and resizing:
public function upload(Request $request)
{
$resizedImage = cloudinary()->upload($request->file('image')->getRealPath(), [
'folder' => 'avatar',
'transformation' => [
'width' => 250,
'height' => 250,
‘gravity’ => ‘faces’,
‘crop’ => ‘fill’
]
])->getSecurePath();
dd($resizedImage);
}Optimize Images On Upload
The code below compresses and optimizes an image:
public function upload(Request $request)
{
$compressedImage = cloudinary()->upload($request->file('image')->getRealPath(), [
'folder' => 'uploads',
'transformation' => [
'quality' => auto,
'fetch_format' => auto
]
])->getSecurePath();
dd($resizedImage);
}Setting the auto value for the fetch_format and quality attributes automatically compresses and optimizes the image in the best way, balancing its visual quality.
Note: As a rule, with fetch_format and quality set to auto, Cloudinary picks WebP or JPEG-XR as the display format for Chrome or IE, respectively. However, if the quality algorithm determines that PNG-8 or PNG-24 is optimal, Cloudinary might pick either of them for display.
