Pros
High controlled degree of compression. The user independently selects the ratio quality/file size; – small file size; – format is compatible and it is displayed correctly in any browsers, text and graphics programs, on all computers, tablets and mobile devices; – suitable for full-color realistic images with a lot of color and contrast transitions; – picture quality is high with small degree of compression. All these features provide tremendous popularity of the format.
Cons
Image may “fall apart” into individual squares – 8×8 pixel blocks when you squeeze it. This occurs because compression algorithm involves analysis of neighboring pixels, due to this smooth color – transitions may become harsh or just disappear; – JPEG is less suitable for working with text or monochrome graphics with clear boundaries; – format does not support transparency and In case of drawing templates, logos, buttons it’s necessary; – every next step of compressing the image degrades its quality
Pros
Good for simple animations and videos Small file size
Cons
Limited to 256 colours Web only
