This class can generate a thumbnail image given the image URL.

It provides a class that extends the Yi2 framework Component class to take an image passed by its URL or file name and generates a thumbnail image.

The generated thumbnail image can be stored in a server-side directory with the file name and a path the class returns.

Build Status Latest Stable Version Total Downloads Latest Unstable Version License

Yii2 component to generate image thumnails of any size.


The preferred way to install this extension is through composer.

Either run

php composer.phar require --prefer-dist daxslab/yii2-thumbnailer "*"

or add

"daxslab/yii2-thumbnailer": "*"

to the require section of your composer.json file.


The basic configuration only requires adding the component to the application:

'components' => [
    'thumbnailer' => [
        'class' => 'daxslab\thumbnailer\Thumbnailer',

Besides that a default value is always provided, all the options can be configured.

'components' => [
    'thumbnailer' => [
        'class' => 'daxslab\thumbnailer\Thumbnailer',
        'defaultWidth' => 500,
        'defaultHeight' => 500,
        'thumbnailsBasePath' => '@webroot/assets/thumbs',
        'thumbnailsBaseUrl' => '@web/assets/thumbs',
        'enableCaching' => true, //defaults to false but is recommended


Once the extension is configured, simply use it in your views by:

//Generates thumbnail with default values specified in the configuration

//Generates a 400px width thumbnail. The height is determined as the width because is not set. 
Html::img(Yii::$app->thumbnailer->get($imageUrl, 400));

//Generates a 400x400 pixels thumbnail and 60% quality 
Html::img(Yii::$app->thumbnailer->get($imageUrl, 400, 400));

//Generates a 400x400 pixels thumbnail and 10% quality
Html::img(Yii::$app->thumbnailer->get($imageUrl, 400, 400, 10));

//Generates a 400x400 pixels thumbnail, 10% quality and not cropping the image
//but inserting it into a box with the specified dimensions.
Html::img(Yii::$app->thumbnailer->get($imageUrl, 400, 400, 10, ManipulatorInterface::THUMBNAIL_INSET));
