JPEG Network Graphics (JNG) is a hybrid format using JPEG-compressed image data with optional PNG-compressed alpha channel.
Kodak DC25 Raw (K25) is an early digital camera raw format from Kodak's DC series cameras, preserving sensor data.
Reach for JNG when your priority is legacy web animation, lossy image sequences — its efficient compression makes sharing fast and storage minimal.
Reach for K25 when your priority is vintage kodak digital camera raw processing — its uncompromising quality ensures every detail is preserved.

No, converting JNG to K25 does not cause additional quality loss — K25 uses lossless compression. However, any artifacts already present in the original JNG file will persist in the K25 output.
K25 files are typically 2-5x larger than equivalent JNG files because K25 preserves all pixel data. This is expected and necessary for lossless quality.
Yes, K25 supports transparency. Alpha channel information from JNG is preserved during conversion.
