JPEG is an acronym for Joint Photographics Experts Group, it is a compression method of photographic images and is also considered as a file format.
O Joint Photographics Experts Group is the name of the group responsible for creating this method, which is one of the most popular image compression methods to date. JPEG (or JPG) allows you to compress a file and get as a final result an image with reasonable quality and small in size. The relationship between image quality and size differentiates JPEG from other formats because it facilitates file storage and distribution.
The compression level can be adjusted, and the more compressed the file in question is, obviously its size will be smaller. However the image quality will also be lower. Furthermore, each time the same JPEG image is recorded, it loses quality, because with this method, the process of saving the file involves compression and a consequent loss of quality.
JPEG is commonly used in creating images in digital cameras, as it has the ability to work with about 16.8 million colors (24 bits). It is possible to identify a JPEG file by its extension, the most common being the ".jpg" and ".jpeg" extensions. The amazing technological advances in graphic terms have resulted in the creation of various image formats. JPEG is one of the most popular formats these days, along with GIF and PNG.
With the appearance of various formats, there was also a need to be able to convert a certain format into another. For that reason, there are several conversion computer programs, for example, from JPEG to PDF.
