JNG files: Frequently Asked Questions

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.
