Сразу скажу, что это расширение предусматривает cropping только для уже загруженных файлов, оно не сможет обрезать файл до его загрузки.

Так же для обрезания я использую composer-пакет "yurkinx/yii2-image": "dev-master", без него не обойтись.

Если предположить, что в бд у $model есть поле image_name, где и будет храниться путь к загруженному файлу относительно директории /images/example/:

<?= $form->field($model, 'image_name')->fileInput(['accept' => 'image/*']) ?>

Original:
<?= Html::img(Yii::$app->request->baseUrl . '/images/example/' . $model->image_name) ?>
<br />

Cropped:
<?= Html::img(Yii::$app->request->baseUrl . '/images/example/cropped_' . $model->image_name, ['id' => 'myImage']) ?>

<br />
<?= Cropper::widget([
    'modal' => true,
    'cropUrl' => ['cropImage', 'id' => $model->id],
    'image' => Yii::$app->request->baseUrl . '/images/example/' . $model->image_name,
    'aspectRatio' => 4 / 3,
    'pluginOptions' => [
        'minCropBoxWidth' => 400, // minimal crop area width
        'minCropBoxHeight' => 300, // minimal crop area height
    ],
    // HTML-options for widget container
    'options' => [],
    // HTML-options for cropper image tag
    'imageOptions' => [],
    // Additional ajax-options for send crop-request. See jQuery $.ajax() options
    'ajaxOptions' => [
        'success' => new JsExpression(<<<JS
            function(data) {
                // data - your JSON response from [[cropUrl]]
                $("#myImage").attr("src", data.croppedImageSrc);
            }
JS
        ),
    ],
]); ?>

После нужно настроить экшен cropUrl, для этого в текущем контроллере добавляем функцию:

public function actionCropImage($id)
{
    $request = Yii::$app->request;
    $model = ModelClass::find()->where(['id' => $id])->one();

    $imagePath = Yii::getAlias('@app/images/example/') . $model->image_name;
    $cropImagePath = Yii::getAlias('@app/images/example/') . 'cropped_' . $model->image_name;
    $x = $request->get('x');
    $y = $request->get('y');
    $width = $request->get('width');
    $height = $request->get('height');
    $rotate = $request->get('rotate');

    $yiiImage = Yii::createObject([
        'class' => 'yii\image\ImageDriver',
    ]);
    /* @var $image \yii\image\drivers\Image_GD|\yii\image\drivers\Image_Imagick */
    $image = $yiiImage->load($imagePath);

    $image->crop($width, $height, $x, $y);
    $image->rotate($rotate);

    $image->save($cropImagePath);

    $response = Yii::$app->response;
    // if is AJAX request
    if ($request->isAjax) {
        $response->getHeaders()->set('Vary', 'Accept');
        $response->format = Response::FORMAT_JSON;

        return [
            'status' => 'success',
            'croppedImageSrc' => $request->baseUrl . '/images/example/cropped_' . $model->image_name,
        ];
    } else {
        return $this->redirect(['update' => $model->id]);
    }
}

from yii2-cropper.
