                            IMAGE FORMATS


Part 1A)
PEG is short for Joint Photographic Experts Group, and is the most popular among the image formats used on the web. JPEG files are very ‘lossy’, meaning so much information is lost from the original image when you save it in a JPEG file.



GIF short for Graphics Interchange Format, is limited to the 8 bit palette with only 256 colors. GIF is still a popular image format on the internet because image size is relatively small compared to other image compression types.


The BMP files are image files within the Microsoft Windows operating system. These files are large and uncompressed, but the images are rich in color, high in quality, simple and compatible in all Windows OS and programs. BMP files are also called raster or paint images.


TIFF is a screenshot of how a TIFF image looks like–TIFF is not compatible for all systems; so to be sure, I uploaded a screenshot in JPEG of a TIFF image preview instead of uploading the original TIFF image here. Notice the crisp quality and rich colors of the photo.

 PGN is a recently introduced format, so not everyone is familiar with it. But PNG has been approved as a standard since 1996. It is an image format specifically designed for the web. PNG is, in all aspects, the superior version of the GIF.

Just like the GIF format, the PNG is saved with 256 colors maximum but it saves the color information more efficiently. It also supports an 8 bit transparency.
