I understand your thought. Yes, the image is sent to the server for several reasons: 1. Perspective. The app is able to render all effects in the client's browser except for the 3d perspective. This is made on the server side 2. Download. Since I want to give the user a "native" download, the only way to do this is with a server. If it would be possible to render (quality) 3d transformations in canvas and to send out a download I event wouldn't need a server for processing the image.
