“This plugin is incredible. It is very well built and very well documented. The design is obviously very clean and sleek as you can tell from the demo, but I was surprised how easy it was to implement. The seller even provides server side scripts that you can use to easily handle the output and saving the images. The number of customizable options is incredible and setup is really easy.”
“Quick response to questions and a great product.”

Beautiful Animations | Today, it’s all about a nice and smooth user experience, this is where Slim delivers big time.
Responsive | In this day and age, of course this plugin is responsive.
Mobile Friendly | Slim has been optimized to also work with touch input on mobile devices.
Browser Cropping | Cropping is done on the client, no image manipulation script required on the server.
Crop | Specify the output ratio, be it square (1:1), portrait (3:4), movie mode (16:9) a custom ratio or the ratio of the input image, Slim has got you covered.
Rotate | Rotate the image to a 90, 180 or 270 degrees angle.
AutoCrop | Slim will automatically crop the image to best fit the specified output ratio.
AutoRotate | 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 was intended.
AutoSize | 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.
Drop URLs | Loads dropped URLs from other websites just as easy as it loads dropped images.
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 | Slim’s code is optimized for performance. On top of optimal code paths, Slims animations assist in making the cropping experience feel smooth and fast.
Standalone | No client-side or server-side frameworks or libraries are required.
PHP Helper Class | Handy PHP helper class included. This makes it easy for you to get to the uploaded images. If you’re planning to use Slim with ASP.Net / NodeJS or any other server side language this file should give you a good indication on how to setup Slim on the server.
Bootstrap and Foundation Support | Tested and works nicely with both Bootstrap and Foundation.
React, Angular and Vue Wrappers | The package contains wrapper modules for both Angular 1.x, 2.0 and React.
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.
Change Labels | All texts and icons can be configured using data attributes.
