A Cool Site for Converting JPG to PNG Graphics and Changing Resolution

I am going to be teaching a new course on how to make journals and one of the issues I had is how to convert graphic jpg files from 72dpi to 300dpi if you don't have Photoshop or something equivalent. Many of the students I will be teaching don't have access to the higher end graphics programs. I will be using PowerPoint to build the journals in this course. I think I have found a solution with a site called Online-Convert.com. It looks like you can easily change the resolution of a graphic. They look Great

The site is called Online-Convert.com http://www.online-convert.com/
