Usage

Let's add into config in your main-local config file before return[]

       $baseUrl = str_replace('/backend/web', '', (new Request)->getBaseUrl());
       $baseUrl = str_replace('/frontend/web', '', $baseUrl);

       Yii::setAlias('@uploadUrl', $baseUrl.'/uploads/');
       Yii::setAlias('@uploadPath', realpath(dirname(__FILE__).'/../../uploads/'));
       // image file will upload in //root/uploads   folder
       
       return [
           ....
       ]

Let's add in your model file

    public $_image

    public function rules()
    {
        return [
            ['_image', 'safe'],
        ];
    }
    
    public function beforeSave($insert)
    {
        if (is_string($this->_image) && strstr($this->_image, 'data:image')) {

            // creating image file as png
            $data = $this->_image;
            $data = base64_decode(preg_replace('#^data:image/\w+;base64,#i', '', $data));
            $fileName = time() . '-' . rand(100000, 999999) . '.png';
            file_put_contents(Yii::getAlias('@uploadPath') . '/' . $fileName, $data);


            // deleting old image 
            // $this->image is real attribute for filename in table
            // customize your code for your attribute            
            if (!$this->isNewRecord && !empty($this->image)) {
                unlink(Yii::getAlias('@uploadPath/'.$this->image));
            }
            
            // set new filename
            $this->image = $fileName;
        }

        return parent::beforeSave($insert);
    }

 echo $form->field($model, '_image')->widget(\bilginnet\cropper\Cropper::className(), [
    /*
     * elements of this widget

     * browseInputId     = #cropper-input-$uniqueId // fileinput in modal
    */
    'uniqueId' => 'image_cropper', // will create automaticaly if not set

Notes

Don't forget to add this line into root in .htaccess file

RewriteRule ^uploads/(.*)$ uploads/$1 [L]

You can set crop image directly with javascript

Sample:

$('button').click(function() {
   // #cropper-modal-$unique will show automatically when click the button
   
   // you must set uniqueId on widget
   $('#cropper-url-change-input-' + uniqueId).val('image.jpeg').trigger('change');   
});
