When we see a program called Free Image Converter, we expect that its primary purpose is going to be to convert images between different file formats. That's not the case with this program, however; it should perhaps more accurately be called Free Image Resizer, because that--and not file conversion--is what it actually does. Still, as long as you're looking to resize images and not actually change their formats, it works fine.
The program's interface is plain and fairly easy to navigate. Buttons let you add either individual images or whole folders of them that you want to resize. You can then specify the desired size in pixels and set the compression quality. The program has several options for renaming files; you can add numbers, prefixes, or suffixes to differentiate the resized files from the originals. You can also specify the directory in which the resized images will be saved. That's about the extent of Free Image Converter's features; if you're looking to do much beyond resize or rename images, this probably isn't the program for you. An online Help file is not particularly helpful, but given the program's paucity of features, this isn't a huge drawback. Overall, Free Image Converter doesn't do anything we haven't seen before, and we've encountered many other image converters with more features. But if you need a no-frills way to resize images, it will do the job.
Free Image Converter installs a desktop icon without asking but uninstalls cleanly.
