What Makes JPG Unique?

JPG images use a lossy compression method, which reduces their storage size at the expense of image quality. Where JPG excels is its ability to achieve up to 10:1 compression without any noticeable degradation in image quality. This makes JPG images ideal for the web and casual photography.

Many photo editing programs let you manually adjust the JPG compression rate, allowing you to find the sweet spot between size and quality. The downside is that JPG images can become increasingly more corrupted with each re-save.

What Is the Difference Between JPG and JPEG?

JPG and JPEG are commonly confused – and for a good reason. They are both file extension of a lossy graphics file format, but one of them also refers to the compression method used by the said file format: JPEG (Joint Photographic Experts Group).

The name stands for joint committee between the International Organization for Standardization and the International Telecommunication Union. The two organizations published the first part of the JPEG standard in 1992 and the rest is history.

It’s important to realize that the JPEG compression method can be saved with different file extensions: JPG, JPEG, jpg, or jpeg. The extensions simply tell other programs or apps that they are dealing with an image file saved using the JPEG compression method. So, when somebody asks you, “what is .jpg file?” you will tell that person that it’s an image file with lossy compression.
