JPG or PNG to WebP converter simple class

Encountered an issue with converting JPG or PNG images to WebP format during upload. I tried using the Intervention Image library and other libraries but got stuck. Below is a simple CodeIgniter 4 library class that converts a JPG or PNG image to WebP during upload and deletes the original uploaded file. Here is the code:

PHP Code:

<?php
namespace Travo\Admin\Libraries;

class ToWebp
{
    private $fullPath;
    private $outPutQuality;
    private $deleteOriginal;
    private $extension;
    private $newFileFullPath;

    public function __construct()
    {
        // Initialize any necessary properties here
    }

    public function convert($fullPath, $outPutQuality = 100, $deleteOriginal = true)
    {
        $this->fullPath = $fullPath;
        $this->outPutQuality = $outPutQuality;
        $this->deleteOriginal = $deleteOriginal;

        if (!file_exists($this->fullPath)) {
            throw new \InvalidArgumentException('File does not exist');
        }

        $this->extension = pathinfo($this->fullPath, PATHINFO_EXTENSION);
        $this->newFileFullPath = str_replace('.' . $this->extension, '.webp', $this->fullPath);

        $sourceImage = $this->createImageFromPath($this->fullPath);

        if ($sourceImage) {
            $this->convertToWebp($sourceImage);
            imagedestroy($sourceImage);

            if ($this->deleteOriginal) {
                unlink($this->fullPath);
            }

            $newPathInfo = explode('/', $this->newFileFullPath);
            $finalImage = end($newPathInfo);

            return (object) [
                'fullPath' => $this->newFileFullPath,
                'file' => $finalImage,
                'status' => 1,
            ];
        } else {
            throw new \RuntimeException('Given file cannot be converted to WebP');
        }
    }

    private function createImageFromPath($path)
    {
        switch (exif_imagetype($path)) {
            case IMAGETYPE_PNG:
                return imagecreatefrompng($path);
            case IMAGETYPE_JPEG:
                return imagecreatefromjpeg($path);
            case IMAGETYPE_GIF:
                return imagecreatefromgif($path);
            default:
                return false;
        }
    }

    private function convertToWebp($sourceImage)
    {
        imagepalettetotruecolor($sourceImage);
        imagealphablending($sourceImage, true);
        imagesavealpha($sourceImage, true);
        imagewebp($sourceImage, $this->newFileFullPath, $this->outPutQuality);
    }
}
?>

To init , $webp = new ToWebp(); 
$result = $webp->convert($orginal_file_path, 70, false);
I have implemented this in my Codeigniter Blog

another simple  approach

PHP Code:

if ($image->isValid() && !$image->hasMoved()) { 
  $newBanner =str_ireplace(['.jpeg','.jpg','.png'],'.webp',$image->getRandomName());
    \Config\Services::image()->withFile($image)
  ->convert(IMAGETYPE_WEBP)
              ->fit(1400, 576, 'center')
              ->save(FCPATH.'/upload/'.$newBanner); 
} 
          $save =[
 'image'=>$newBanner ?? "imageplaceholder.png",
 ];
