The upload service is used to upload an image when you want to apply several transformations to it. By uploading an image first, you'll receive a transaction_id which you can use repeatedly for transformations and thereby avoid having to upload an image for each and every one. If you're sure you only want to do a single transformation to an image, there's no benefit to using this service. Just jump right to that service.

Limitations: Supported source image formats are JPG, PNG, TIFF and WEBP.

Source Image: You can source the image by providing a file or a URL to an online image.
