jif

Jif is a brand of peanut butter marketed in the United States and Canada. It is produced by The J.M. Smucker Company and has been sold since the late 1950s. Jif offers a range of varieties, including Creamy, Crunchy, Natural, and Reduced Fat, and is commonly used on sandwiches and in baking. The product is widely distributed through grocery stores and online retailers, and its branding emphasizes a smooth texture and consistency that appeals to a broad consumer base.

In digital imaging, JIF has been used as an acronym for JPEG Interchange Format. This name refers to an early container standard for storing JPEG-compressed images. The .jif extension was used by some programs to denote such images, but it is not as common today as the .jpg or .jpeg extensions. In practice, the JPEG File Interchange Format (JFIF) is the dominant interchange wrapper for JPEG data, and JIF is less commonly encountered. The terms are related but refer to different naming conventions within the JPEG ecosystem.

Other uses of the acronym JIF or similar capitalization exist in various fields, but the two meanings above are the most widely recognized in contemporary contexts.
