jQuery SDK


Cloudinary is a cloud-based service that provides an end-to-end image and video management solution. The jQuery SDK provides simple, yet comprehensive file upload, manipulation, optimization, and delivery capabilities that you can implement using code that integrates seamlessly with your existing jQuery application.

The following instructions describe Cloudinary's jQuery client-side library. For the server side NodeJS library, see the NodeJS documentation.

Quick example: Transformations

The following Cloudinary URL and corresponding jQuery code delivers the image below in an https delivery URL, including all of the following transformations:

  • Thumbnail crop to a size of 150x150 pixels using face detection gravity to automatically determine the location for the crop
  • Rounded corners with a 20 pixel radius
  • Sepia effect
  • Overlay of the Cloudinary logo on the southeast corner (with a slight offset). The logo is scaled down to a 50 pixel width, with increased brightness, and partial transparency (opacity = 60%)
  • Rotated by 10 degrees
  • Converted to and delivered in PNG format (the originally uploaded image was a JPG)

$.cloudinary.image("front_face.png", {secure: true, transformation: [
  {width: 150, height: 150, gravity: "face", radius: 20, effect: "sepia", crop: "thumb"},
  {overlay: new cloudinary.Layer().publicId("cloudinary_icon"), gravity: "south_east", x: 5, y: 5, width: 50, opacity: 60, effect: "brightness:200"},
  {angle: 10}

Quick example: File upload

The following code demonstrates defining a file input field for client-side image or video file upload, and then initializing the input field for use with the cloudinary_fileupload method:

<input name="file" type="file" class="cloudinary-fileupload" data-cloudinary-field="image_id" 
$(document).ready(function() {

jQuery SDK features

  • Build URLs for image and video manipulations
  • jQuery helper methods for embedding and transforming images, and more
  • Direct unsigned file upload from the browser


Install the jQuery library using a package manager:

# For NPM:   
npm install jquery --save
npm install blueimp-file-upload --save
npm install cloudinary-jquery-file-upload --save

# For Bower: 
bower install cloudinary-jquery --save

The optional --save parameter saves the dependency in your package.json or bower.json file, respectively.


1. Include jQuery

Include the files in your HTML page:

<script src="[folder-path]/jquery/dist/jquery.js" type="text/javascript"></script>
// the following files only need to be included in order to support client-side uploading
<script src="[folder-path]/blueimp-file-upload/js/vendor/jquery.ui.widget.js" type="text/javascript"></script>
<script src="[folder-path]/blueimp-file-upload/js/jquery.iframe-transport.js" type="text/javascript"></script>
<script src="[folder-path]/blueimp-file-upload/js/jquery.fileupload.js" type="text/javascript"></script>
<script src="[folder-path]/cloudinary-jquery-file-upload/cloudinary-jquery-file-upload.js" type="text/javascript"></script>
// [folder-path] is the mapping to the resources in your web application

2. Set Cloudinary configuration parameters

To use the Cloudinary jQuery library you have to configure at least your cloud_name. You can additionally define a number of optional configuration parameters if relevant. You can find your account-specific configuration credentials in the dashboard of our Management Console.

An instance of the Cloudinary jQuery main class, CloudinaryJQuery, is already instantiated as $.cloudinary. Setting the configuration parameters can be done either programmatically in each call to a Cloudinary method or globally using the Cloudinary config method, for example:

$.cloudinary.config({ cloud_name: 'sample', secure: true});

Sample projects

For additional useful code samples and to learn how to integrate Cloudinary with your web applications, take a look at our sample projects for Ruby on Rails, PHP and Django. You should also take a look at the following sample project of a dynamic HTML page using Cloudinary's jQuery plugin that performs direct uploading from the browser with uploading progress, an image preview with advanced transformations:
