With Cloudinary's transformation options, you as web or mobile developers can manipulate images in real time through dynamic URLs, from optimization and responsive delivery to other tasks, complete with cool effects.

A few years ago, post-processing a digital image generally required a high level of skill and expensive software such as PhotoShop.
