Hi, folks will show how you can convert any image to webp image.

Why Webp

WebP is making headway in the image format space this year. The image format — which is developed by Google — uses both lossy and lossless compression by utilizing technology that Google purchased from On2 Technologies.


WebP has been around a while now, actually, and it first made headlines in a 2010 Google press conference. But, like any new technology, it had some initial rough patches. Today, WebP is on version 1.0.0, so we thought it would be a great time to talk about what makes WebP so powerful, and why it’s a fantastic option for web designers and developers.


Before I proceed to describe what WebP actually is, let us focus on why it matters—it’s not only about making images smaller, but it’s also about why and how the images need to be made smaller.


You may have heard about design mistakes killing your SEO and conversion rates. While there are some aspects that CSS or JavaScript are responsible for, like blocking rendering, the images nowadays are a huge part of any website’s weight. Therefore, users on slower connections will have trouble interacting with your website (unless it’s an AMP).

Just recently, It’s an interesting area of expertise, where you take care of lots of small things to deliver one big thing—a superfast, superlight website that reads on any device and looks amazing at the same time.


Chances are, you’ve seen WebP images before. If you open Naijacrawl in Google Chrome, all of those thumbnails are going to be WebP thumbnails. If you were to open the Facebook app on your android phone, all of the images that you see would be WebP. It’s definitely being utilized by various companies around the world to increase performance.


So let's see how you can do the same using laravel to convert your images to webp image.


Note this works in all laravel versions


I assumed you have a project already or you can create one by using this command


composer create-project laravel/laravel webimage --prefer-dist


You must have installed a composer before you can run the command.


We need a controller so let's create one

php artisan make:controller ImageWebpController


Inside the controller, we will write a code that will process our image and convert it to webp inside a folder


What it Requires

file extension

file name

folder

<?phpnamespace App\Http\Controllers;


use Illuminate\Http\Request;
use Illuminate\Support\Str;


class ImageWebpController extends Controller {


    public function webpImage(Request $request) {
        if ($request->hasFile('file')) {
            $file = $request->file('file');
            $extension = $file->getClientOriginalExtension();
            $rand = '-' . strtolower(Str::random(10));
            $name = $rand . '.' . $extension;
            return $this->processImage($file, $name);
        }
    }


    private function processImage($file, $name) {
        $file->move(public_path('/test/image'), $name);
        //convert to webp 
        $webp = public_path() . '/test/image/' . $name;
        $im = imagecreatefromstring(file_get_contents($webp));
        $new_webp = preg_replace('"\.(jpg|jpeg|png|webp)$"', '.webp', $webp);
        imagewebp($im, $new_webp, 50);
        return [
            'message' => 'image successfully converted to webp. check your folder to see it'
        ];
    }


}


from what i did, i check if the request is a file before proceeding , have to get extension of the file and use it make a slug name for the image, because i don't want it to carry original name.

$extension = $file->getClientOriginalExtension();

I have to use str function to form a characters for the name of the image

 $rand = '-' . strtolower(Str::random(10));
//final 
name$name = $rand . '.' . $extension;

I needed another private function because i want to separate my code for easy to read using processImage function.

 private function processImage($file, $name) {
        $file->move(public_path('/test/image'), $name);
        //convert to webp 
        $webp = public_path() . '/test/image/' . $name;
        $im = imagecreatefromstring(file_get_contents($webp));
        $new_webp = preg_replace('"\.(jpg|jpeg|png|webp)$"', '.webp', $webp);
        imagewebp($im, $new_webp, 50);
        return [
            'message' => 'image successfully converted to webp. check your folder to see it'
        ];
    }

After i called it to the main function which is webpImage function .

Inside processImage function , the file is moved to my public folder called test/image before converting it to webp image

//get image that we want toconvert 
$webp = public_path() . '/test/image/' . $name;
//create the image       
 $im = imagecreatefromstring(file_get_contents($webp));
//accept image extensions of jpg,png,webp 
$im = imagecreatefromstring(file_get_contents($webp));        
$new_webp = preg_replace('"\.(jpg|jpeg|png|webp)$"', '.webp', $webp);
//make the webp image and set the quality to 50 //the more quality the more it becomes broght and increase mb// you can set to 100 which means no quality will be reduced        
imagewebp($im, $new_webp,50);

From my code i didn't add validation rule which you can do it if you needed it , just to make it allow only files and extension type
