Pageflow can process almost all image, audio and video format and automatically converts uploaded files into different target formats and output qualities. 

When a story is entered, Pageflow checks the respective network situation of a user and then delivers the best possible quality of a file. This enables a smooth performance, even in the somewhat slower mobile network.

All media formats should be available in a high quality and should not have already been compressed into web formats. This is because if media that are already heavily compressed are compressed again, this can lead to poor results.

Since background images and videos are always displayed full-screen and errors are quickly noticed with such large formats, it is advisable to pay attention to a high resolution. In addition, background images and videos should be created in 16:9 format, as this is closest to the aspect ratio of most landscape screens.
