I really like Yii2 Dropzone.

Installation:

composer require --prefer-dist perminder-klair/yii2-dropzone "dev-master"

Usage:

 [
           'url'=> Url::to(['resource-manager/upload']),
           'paramName'=>'image',
           'maxFilesize' => '10',
       ],
       'clientEvents' => [
           'complete' => "function(file){console.log(file)}",
           'removedfile' => "function(file){alert(file.name + ' is removed')}"
       ],
   ]);

   ?>

Controller:

public function actionUpload(){

        $model = new ResourceManager();
        $uploadPath = Yii::getAlias('@root') .'/uploads/';

        if (isset($_FILES['image'])) {
            $file = \yii\web\UploadedFile::getInstanceByName('image');
          $original_name = $file->baseName;  
          $newFileName = \Yii::$app->security
                            ->generateRandomString().'.'.$file->extension;
           // you can write save code here before uploading.
            if ($file->saveAs($uploadPath . '/' . $newFileName)) {
                $model->image = $newFileName;
                $model->original_name = $original_name;
                if($model->save(false)){
                    echo \yii\helpers\Json::encode($file);
                }
                else{
                    echo \yii\helpers\Json::encode($model->getErrors());
                }

            }
        }
        else {
            return $this->render('upload', [
                'model' => $model,
            ]);
        }

        return false;
    }
