What is the main function of Akamai's Image Manager?

The main function of Akamai's Image Manager is to optimize image content for web delivery. This service helps ensure that images are not only displayed in high quality but also load quickly and efficiently across various devices and network conditions.

By using techniques such as automatic resizing, reformatting, and compression, the Image Manager reduces image file sizes without sacrificing quality, which is crucial for improving website performance and user experience. This optimization is particularly important given the increasing variety of devices, from desktop computers to smartphones, that access web content, each potentially requiring different image specifications.

The other functions suggested, such as creating high-resolution images or securely storing images, do not align with the primary purpose of the Image Manager, which focuses specifically on optimizing images for speed and delivery rather than their creation or storage. While the process might involve interaction with cloud services, the key value proposition lies in the optimization that enhances web performance.
