"Does what you ask, but not that Intuitive."
The program did open and convert the picture just fine.
It wasn't until I read some of the reviews that I realized you could enter resolution numbers in the box. Initially the 4.4MB picture opened at a resolution of 142x142. It looked ridiculous! Since there is no menu or help button, I initially thought the program was a dud. Once I realized that you could change the resolution numbers, things went off without a hitch!
Just know that you can set the resolution in the boxes at the top left and this program works fine.
