Document Summary

Indexed colour indexed colour can look pretty good even though we will only ever have at most 8-bit colour (or. How do we download faster: make our image files size smaller less pixels (but that will change the size it is displayed at on the screen) How to download faster and keep image the size we want it: compress the image file, use tricks to make file smaller without losing the quality of the image or the size (in pixels. Compression key concept: compress as much as you can without sacrificing quality (losing information! Is there a way we can stuff the bits and bytes down into less bit and bytes: yes: lossless. For example: when packing a suitcase, what are your two options for filling the suitcase: a: folding carefully and sitting on the suitcase lossless, b: leaving some unimportant stuff at home and using a smaller suitcase lossy.
