Created by Kim Asendorf, ExtraFile is conceptional software with practical usage. It’s main intention is to offer an alternative to the static system of image file formats. It is also an attempt to address an alternative image file format, a piece of art, far away from the mainstream and commercial standards.
The freedom not to have to pay attention to the file size or the loading and saving times provides the option to implement artistically byte orders, odd quality behaviours and visual designed formats. ExtraFile is breaking the rules of commercial formats like JPG, PNG or TIFF. It is a pioneer art project in storing image data. The process and the resulting bytes, regardless of content, become the artwork itself.
ExtraFile.app is a native Mac OS X image converter application written in objC with the ability to open, preview and save the most common image file formats. It offers the possibility to use the seven build-in formats, 4Bit Components , Block Ascii , Block Indexed , Channel Compressed Image , Monochrome Collector File , Uniform Spectrum and the ExtraFile Format , to store image data.
