What is JPG and when to use this format

JPG was designed to compress and store full-color photos. Depending on your preference, you can use this format as "JPEG" or "JPG" as both are acceptable variants of one acronym, namely, Joint Photographic Experts Group. Despite being the property of the association of American photographers, the association itself says it is an open format.

This format has become very popular especially after the introduction of digital photography. Its main advantages are the possibility of fast, non-resource-consuming and very strong compression of full-color images. JPG allows you to flexibly adjust the degree of image compression: from 0% (strong compression) to 100% (without compression). Typically, 60% -75% is enough to significantly reduce the weight of the file, while maintaining excellent quality on most screens. In addition, JPG files “weigh” a little. They can be easily transferred from phone to phone, by email or put on the Internet. Also, a small size allows you to store a large number of images.
