Graphics file format developed by MediaBin, who was acquired by Interwoven Systems; stores an image with fractals, which are smaller graphics that can be repeated within an image and resized without losing image quality; used for fill textures or other repeatable patterns; also used to create high-definition prints.

FIF files are created using a lossy compression algorithm. The algorithm identifies common fractals within the original image and then reconstructs the image using the fractals. This allows FIF files to be compressed at ratios as high as 2500:1. FIF files can be saved and loaded in Adobe Photoshop with the Genuine Fractals plug-in.
