Color differences jpeg and png

[rich2005]

Putting colour calibration and most users having a too bright monitor to one side.
Take your troublesome pair of png / jpeg and use Imagemagick to list the properties for each.

Code:

identify -verbose image.ext

and compare for difference. If there are big difference, then some investigation needed



For the same RGB image exported in each format by Gimp there are small differences. Jpeg is biased towards vision rather than a RGB monitor display, but it is minor. A good (my opinion) recent article https://parametric.press/issue-01/unraveling-the-jpeg/

If they come out virtually identical, then surely the problem is software related.
