Compressing BMP files is a good idea if you want to share those files with others or save space on your computer. BMP (bitmap) files are uncompressed pixel-based images. While the file format enjoys universal support among Mac and Windows applications, the large file size makes it less than ideal for general use on both the Web and a local computer. Convert a bitmap image to a smaller file format, or archive it in a zipped folder.
