This looks to be the same software known as “Picture Colorizer” which is a freeware program. It’s the same developer.
Haven’t tried this, but the problem I had with “Picture Colorizer” was that it was useless without an internet connection.
Meaning, it sends the pictures to the website and all editing is done there, which means once your picture goes to their website then whatever happens to your photos after that is up to them.
Will this work without an internet connection? Is it the same as Picture Colorizer?
