IMAGE FORMATS
made by faunaman

I am going to talk about image formats that are very important in Pixel Art, i am talking about this becouse a lot of people dont know what they do when they are saving a image and they save it in the wrong format that makes the image quality low this is a common error thats why i made this tutorial for you to understand more about image formats.

Formats:


PNG: This image haves high image quality, small space usage resuming the best image format for a lot of people and png's can handle transparency.
Size: 329 bytes


GIF: This image haves medium image quality, medium space usage and gif's can handle animation and are better for icons.
Size: 997 bytes


JPEG: This image haves low image quality, medium space usage and jpeg's is the best format for to safe photos.
Size: 1.009 bytes


BMP: This image is bmp of 24 bits and haves medium-high image quality and high space usage.
Size: 1.782 bytes

BMP Formats:


BMP 24-bit: This image haves medium-high image quality and high space usage.
Size: 1.782 bytes


BMP 256 colours: This image haves low-high image quality and high space usage.
Size: 1.654 bytes


BMP 16 colours: This image haves normal image quality and low space usage.
Size: 406 bytes


BMP Monochrome: This image haves normal image quality, very low space usage and only supports black and white colors.
Space: 158 bytes

.bmp are not medium quality they are lossless.
.png is a compressed version of .bmp
.bmp monochrome is black and white only.
 
Also lossy formats will deteriorate with each save and load cycle.
 
You might want to mention that too.
 
You can find more information here:

They do not lose any of the original quality. They stay the same, so they would be high quality.

"Lossless data compression is a class of http://en.wikipedia.org/wiki/Data_compression - data compression http://en.wikipedia.org/wiki/Algorithm - algorithms that allows the exact original data to be reconstructed from the compressed data. This can be contrasted to http://en.wikipedia.org/wiki/Lossy_data_compression - lossy data compression , which does not allow the exact original data to be reconstructed from the compressed data."

also, Ii would put more emphasis on a description about how does saving in each format affects people's works, rather than giving a generical tech info of each format. the image does not really work as an ilustration of the explanation.
