1. I really love to have a dedicated image manipulation API which is not tied to a (headless) CMS.
2. I don't care about speed. Image manipulation can never be instant, and while the operation may be super fast on your end, the image data still needs to travel the wire, and be rendered on the UI. Your performance argument therefore is mute for me.
3. I do care a lot about having smart features like face detection, auto rotation, optimization (e.g. optipng), this should be on your start page.
4. I'm unable to find the address of your company on the homepage. This is a no go, especially when dealing with images which are potentially sensitive user content, I need to know exactly who is responsible for operating the service.
