JavaScript SDK (Legacy) image and video upload
Last updated: Aug-03-2022
On this page:
When using the cloudinary-core 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 endpoint
The upload endpoint is https://api.cloudinary.com/v1_1/${cloudName}/upload. To use the endpoint in your application, write a function that calls the Cloudinary upload endpoint and pass:
- an unsigned upload preset with the upload method options you want to apply for all files
- the file(s) to upload
- other unsigned upload parameters to apply to the selected files (e.g.
tags, if needed).
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.
Note
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. Code examples
- Code sample: Implement the upload widget.
- CodeSandbox: Upload multiple files using a form in pure JavaScript using the Cloudinary upload endpoint.
- CodePen: Use XMLHttpRequest to upload files in pure JavaScript using the Cloudinary upload endpoint for unsigned uploading with an upload preset.
- Glitch: Perform signed uploads from the browser by generating a signature on the server.
