Beautiful Animations

Today, it’s all about a nice and smooth user experience, this is where Slim delivers big time.


In this day and age, of course this plugin is responsive.

Browser Cropping

Cropping is done on the client, no PHP image manipulation script required.


Specify the output ratio, be it square (1:1), portrat(3:4), movie mode (16:9) or a custom ratio, Slim has got you covered.


Slim will automatically crop the image to best fit the specified output ratio.


Specify the maximum size of the output image and Slim will scale down the image to fit perfectly.

Tip: Use AutoSize with a square ratio to quickly crop avatars.

Device Orientation

Mobile devices can embed rotation information in photographs, this often results in rotated or incorrectly read imagery. Slim automatically corrects this and presents the photo the way it should be.

AJAX and Form POST

Upload cropped images with AJAX or with a traditional form post. When using AJAX Slim shows a neat progress indicator.

Very Fast

Of course there’s a maximum amount of data your user can transfer, we can’t help that. But we can make sure Slim itself is not slowing down the users’ device. Slim’s code is optimized for performance.

On top of optimal code paths, Slims animations assist in making the cropping experience seem smooth and fast.

PHP Helper Class

Handy PHP helper class included. This makes it easy for you to get to the uploaded images.

Bootstrap and Foundation Support

Works nicely within Bootstrap and Foundation.

Easy to Configure

Setting up Slim is a matter of adding some data attributes to your HTML and presto, you’re ready to crop and upload images.

Edit Server Images

Slim can also load images via URL, this allows you to use Slim to quickly crop server images.

Tip: Line up server images, Slim will auto crop, do a visual survey, if all is fine, upload back to server.

Vanilla JavaScript and jQuery

Whether you’re an old school JavaScript fanatic or a jQuery lover, Slim’s got you both covered. The package also contains an AMD, CommonJS and Global build version of Slim.

Control Labels

All texts and icons can be configured using data attributes.

JavaScript API

You can control the cropper from your scripts using the JavaScript API.
