A treasure trove
Jpg, Gif etc .. what’ does it all mean?
GIF = Graphics Interchange Format
JPEG = Joint Photographic Experts Group
PNG = In January 1995 Unisys, the company Compuserve contracted to create the GIF format, announced that they would be enforcing the patent on the LZW compression technique the GIF format uses. This means that commercial developers that include the GIF encoding or decoding algorithms have to pay a license fee to Compuserve. This does not concern users of GIFs or non-commercial developers. So a small group made a completely free image format called PNG which is actually superior to GIF.
JPEG is superior to GIF for storing full-color or grey-scale images of "realistic" scenes; that means scanned photographs and similar material
GIF does significantly better on images with only a few distinct colors, such as line drawings and simple cartoons,
THE BEST FORMAT
TIFF
TIFF files are larger than JPEG files, but they retain the full quality of the image. They can be compressed or uncompressed, but the compression scheme is lossless, meaning that although the file gets a little smaller, no information is lost.
However, a lot of sites do not accept TIFF files, so I personally always use TIFF if I can, but if not possible, then I use JPG.
Agree or disagree?
