p.1 #3 · Compression Software question - ftp | |
In a word, no. ZIP is a standard algorithm that is the same for all types of files. The way JPGs are compressed takes into account the fact they are images, and actually does some reasonably smart inter-scanline compression. ZIP takes a (in this case binary) file, and looks for common bit patterns. Great for text (think how often the letter 'e' is used in English). Ineffective for binary. And, ZIP is lossless, which is nice (and necessary for text), whereas JPG can be very lossly if you crank up the compression.
