JNG to EPI Conversion: FAQ

What are JNG files?

JNG (JPEG Network Graphics) is an offshoot of the PNG/MNG family that packages a JPEG-compressed RGB image together with a lossless PNG-style alpha channel, giving you full transparency at smaller file sizes than an equivalent PNG. It uses the same chunked structure as PNG, making it easy to embed metadata or animation cues when paired with MNG. Despite its clever hybrid design, mainstream browsers and tools never embraced JNG, so it remains a niche format overshadowed by PNG, WebP, and AVIF.

What are EPI files?

EPI (Encapsulated Interchange Script) is an interchange format associated with Adobe Illustrator and represents a vector file used by graphic designers to create and edit drawings. EPI files can contain maps, logos, page layouts or several other types of drawings including text and graphics. Due to their vector format, EPI files can be incompatible with most popular image viewers.
