Are you sick of hearing those extra “E” and “G” in JPEG? Wish there was a shorter and sassier version? Well, fear not, because JPG is here to save the day! Although these two file formats are often used interchangeably, there are some technical differences between them. In this paper, we will explore the similarities and differences between JPEG and JPG, and provide step-by-step instructions on how to convert JPEG to JPG on a Mac.

1. Understanding JPEG and JPG: Similarities and Differences

JPEG (Joint Photographic Experts Group) and JPG are both widely used image file formats for storing and sharing digital images. They are often used interchangeably, but they do have some technical differences.



JPEG is a commonly used image format that employs lossy compression, which means it reduces file size by selectively discarding some image data. It is designed to efficiently store photographic images with complex color variations and smooth gradients. JPEG files use the .jpeg or .jpg file extension. The format enables a wide range of color depths and is widely supported across different devices and software applications. JPEG compression allows for significant file size reduction while maintaining acceptable image quality, making it ideal for web pages, online sharing, and digital photography.



JPG is a file extension that stands for Joint Photographic Experts Group, the same as JPEG. The primary difference between JPEG and JPG lies in the file extension itself. JPG is a shortened version of JPEG and was adopted to conform to the three-character file extension limit on some operating systems. Technically, there is no difference in terms of image content or compression between the two formats. They both utilize the same lossy compression algorithm to reduce file size while preserving image quality.

In summary, the terms JPEG and JPG refer to the same image file format, with the latter being a shortened version of the former. The only difference between them is the file extension used, with JPEG having a four-character extension and JPG adhering to the three-character limit.
