JPEG File Size Comparison
JPEGs support 24 bit color and are therefore able to reproduce the subtle variations in color in photographic type images. It is called a lossy file format because in order for it to compress the file, it selectively discards data, a method which can degrade sharp details in an image. Also, JPEGs always add artifacts to the image in the form of blocky or wave-like patterns, so it is better to always save from the original file, and never from another JPEG. |
