JNG to FLIF 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 FLIF files?

FLIF (Free Lossless Image Format) is a royalty-free format launched at the end of 2015 as "work in progress" with the aim of offering a better alternative for storing lossless images than the existing PNG, WebP, BPG, JPEG2000 and JPEG XR. FLIF provides similar image quality as the other extensions, but in a file size than can be up to 74% smaller. The new format uses a form of the Adam7 algorithm for compressing images, offering progressive interlacing that allows users to obtain a reasonable encoding of an image even from a partial download.
