Redback Graphics

Saving images? What format is best?

jpg had long been the dominant format for saving web images, but now png is the preferred format in many cases.
A png is most suited to graphics with text or content that needs to be crisp and sharp with excellent clarity to blocks of colour. Can be saved with a transparent background like a gif.
A jpg is the better option for photographs. jpg’s can be optimised to reduce file size with little visible loss of quality, but reducing file size excessively can be noticeable to quality.
A gif can be static (one image) or animated (a set of gifs forming a simple animation). A gif can also have a transparent background.
tif is generally only used by industry professionals in the print industry. File sizes are large, but quality is excellent (high res tif).
bmp (Windows bitmap) is rarely used these days, file sizes are large and quality is poor (comparitively).
