Nikon Electronic Format (NEF) is Nikon's raw image format containing unprocessed sensor data from Nikon D-Series and mirrorless cameras.
JPEG Network Graphics (JNG) is a hybrid format using JPEG-compressed image data with optional PNG-compressed alpha channel.
Reach for NEF when your priority is nikon photography, professional post-processing — its uncompromising quality ensures every detail is preserved.
Reach for JNG when your priority is legacy web animation, lossy image sequences — its efficient compression makes sharing fast and storage minimal.

Yes, converting NEF to JNG uses lossy compression, which reduces file size by discarding some visual data. Set quality to 85-95% for a good balance of quality and file size.
JNG files are typically 50-80% smaller than NEF files because JNG uses efficient lossy compression. The exact reduction depends on quality settings.
No, JNG does not support transparency. Any transparent areas in your NEF will be filled with a solid color (usually white) during conversion. Use PNG or WebP if transparency is needed.
