Pixelation can be done dynamically (Manual effort in your graphics program falls away. Graphics must not be known beforehand.)
The computational power required is outsourced to the client side. In contrast to a server-side solutions (eg using PHP & Imagick), the computational load is distributed to the users. This helps to keep the server load low, if you have a lot of visitors.
The pixelation should be used rather as design or graphic effect, since the data is only sent not pixelated to the client. So if you really want to hide faces and picture information the pixelation still needs to be done before delivery to the […]
