JavaScript SDK image and video upload

When using the JavaScript SDK, you can use one of several options to upload files directly to Cloudinary without the need for server-side operations or authentication signatures.

Upload options


  • Upload widget: A ready-made, responsive user interface that enables your users to upload files from a variety of sources directly to Cloudinary. This UI can be easily customized and embedded within your web application with just a few lines of code.

  • Upload endpoint:${cloudName}/upload. To use the endpoint in your application, write a function that calls the Cloudinary upload endpoint and pass:

  • jQuery SDK with Blueimp File Upload adapter: If you are using jQuery in your app, you can take advantage of the built-in upload functionality in Cloudinary's jQuery SDK. This solution uses modern HTML5 cross-origin resource sharing (CORS) and gracefully degrades to a seamless iframe based solution for older browsers.

Each of the upload options described above can also be performed as a signed upload, but in this case, an authentication signature must be generated on your backend server. This can be implemented in conjunction with one of Cloudinary's backend SDKs, which implement helpers to automatically generate the authentication signature for the upload.
