SFW is a proprietary image format from Seattle FilmWorks photo processing.
.wbmp refers to the wireless application protocol bitmap monochrome graphics file format. The format was initially developed by the WAP forum which later become part of the open mobile alliance. WBMP files are optimized for mobile devices prior to the advent of smartphones and is categorized as a raster image file format. Mobile network services such as SMS and MMS on GSM carriers typically have compatible support for this format, allowing users to send graphics saved in this format.

The wbmp file format only supports a color palette of black and white which aids in keeping file sizes at the minimum possible. Binary integers are used to differentiate pixels of opposing colors. The file structure consists of several fields including the type field which represent the type of image, a fixed header of 1 byte in size, a width and height field to define the pixel resolution of the file, and finally the data field which holds the image data.
