Compare Images

Ellié Computing Merge compares and displays differences between images. Several display modes are available to cope with different images natures (photography, charts...)
ECMerge computes metrics such as the PSNR or MSE if you want to compare the quality of the conversion between image formats (e.g. converting from BMP to JPG)
You can alter the alignment of images as well as their dimensions before comparison and export the comparison image in a report or the clipboard.
