In the early '90s GIF's were replace by the new JPG and PNG formats, which offered sharper image resolution and more efficient image encoding. Created in 1987 by CompuServe and developer Steve Wilhite it was designed to save precious memory whilst providing a convenient container to display images. The original intended use of the format was quite different to its use today. The GIF has been around for 30 years and its history is legendary - it has gone from the brink of obsolescence to widespread use thanks largely to the advent of social media and Internet meme culture. The GIF gets its name from the fact it is an image file saved in the Graphical Interchange Format. This compression can affect quality, but this loss of quality isn’t noticeable to most users. JPG is a ‘lossy’ format, meaning that it is compressed to save storage space and make it easier to share. JPEG stands for Joint Photographic Experts Group, which is the name of the committee that standardised the format. However, you can usually adjust settings to save into other formats if needed. Many cameras, smartphones, and basic photo or drawing programs will automatically save into JPG format. JPGs are 2D pixel-based ‘raster’ images, which makes them better for photographs or scans, rather than digital illustrations which are often better as ‘vector’ images. JPG is a universal format which can be opened by almost all image-viewing or -editing programs, by web browsers, and by certain other apps, and they’re supported by most devices. JPG, or JPEG, is one of the most widely used digital image formats.
