JFIF

The JPEG File Interchange Format (JFIF) is an image file format standard published as ITU-T Recommendation T.871 and ISO/IEC 10918-5. It defines supplementary specifications for the container format that contains the image data encoded with the JPEG algorithm. The base specifications for a JPEG container format are defined in Annex B of the JPEG standard, known as JPEG Interchange Format (JIF). JFIF builds over JIF to solve some of JIF's limitations, including unnecessary complexity, component sample registration, resolution, aspect ratio, and color space. Because JFIF is not the original JPG standard, one might expect another MIME type. However, it is still registered as image/jpeg.

JXL

A JXL file is a JPEG XL file, which is a royalty-free, open standard image file format for compressing raster graphics. JPEG XL supports both lossy and lossless compression, and is designed to be used on the web. It's intended to outperform other popular web image formats, such as PNG, JPEG 2000, GIF, and WebP. JPEG XL supports both lossy and lossless compression modes. Lossy compression is similar to JPEG, and is good for images with lots of gradients. Lossless compression is similar to PNG, and is good for images with lots of sharp contrasts.
