What is the difference between jpg and jpeg?

JPEG (Joint Photographic Experts Group) is a commonly used image compression format that is synonymous with both "JPG" and "JPEG." There is essentially no difference between JPG and JPEG—they represent the same file format. File Extension: JPG: It uses a three-letter file extension, often seen as ".jpg." JPEG: It uses a four-letter file extension, commonly seen as ".jpeg." Usage: Both "JPG" and "JPEG" refer to the same image file format, and they are used interchangeably. History: Originally, the file extension ".jpeg" was used to represent JPEG files. However, due to limitations in some operating systems and software, the three-letter extension ".jpg" became more widely adopted and is now the more common and recognized extension. Compatibility: Most modern systems and applications support both ".jpg" and ".jpeg" extensions. However, for simplicity and broader compatibility, ".jpg" is often preferred. File Format: Both ".jpg" and ".jpeg" files use the same JPEG compression algorithm and represent the same type of image file. In summary, "JPG" and "JPEG" refer to the same image file format and are used interchangeably. The choice between ".jpg" and ".jpeg" for the file extension is largely a matter of convention, with ".jpg" being more common and widely recognized.
