Description	🔵 The SFW format is a raster graphics format used for storing bitmap images. It was developed by Seattle FilmWorks and is used mainly for storing photographs. The SFW format uses lossless compression and supports 24-bit color depth.
Technical details	🔵 The SFW file format is a proprietary format, and the specification is not publicly available. The format is based on the RLE (Run-Length Encoding) compression algorithm, which compresses the image by encoding runs of identical pixels into a shorter representation. The SFW file consists of a header and the compressed image data. The header contains information such as the image size, resolution, and color depth. The compressed image data is stored in a sequential order, row by row.

Description	🔵 GIF, Graphics Interchange Format, is one of the most popular bitmap image formats on the World Wide Web, allowing you to share images. It also supports transparent views of various animations. Such files are used to develop web advertising with sequentially changing pictures and the graphics shell of video files. They use scan-line images with the depth parameters up to 256 colors of the RGB palette. The process of compressing files in GIF does not affect the quality in any way, as there is no loss because of the compression technique. Due to this, it is possible to convert to other formats while preserving the original image properties. Many applications open the extension to view and process images and video content installed on PCs and mobile devices regardless of OS.
Technical details	🔵 The format was developed by Compuserve specialists, especially for its use in the web environment, which provided broad public access to data on such files. The extension uses the LZW algorithm to carry out a parallel process with the removal of segments containing insufficient information. This ensures the preservation of high-quality pictures. Thanks to the Lempel-Ziv-Welch algorithm, the format handles graphic files with repeating sections well, particularly images with a large number of single-color pixels horizontally. Interlaced data storage is also possible. Scan-line data is compressed to the smallest size. Reducing the number of colors required to create an image is provided by removing shades unnecessary to perform this process. The range of available GIF colors is from 2 (black and white) to 256 while reducing the number of colors leads to a decrease in the file size.
