UnFREEz is a plain and simple application that can merge GIF files.

This is a portable product, so installing it is not necessary. You can simply place UnFREEz on an external device and directly run the executable file on any computer. Furthermore, your Windows registry entries will not be affected.

The interface of UnFREEz is based on a small window in which your options are pretty limited.

So, you can join one or multiple GIF files by using the "drag and drop" method and then press the "Make Animated GIF" button.

In addition, you can enable UnFREEz to loop animation, as well as set the frame delay, remove frames or clear the entire list. Moreover, you can view information for the selected frame on the right side of the window, as well as its dimensions. After you initiate the merging process, you can select the output name and directory.

The program uses a very low quantity of system resources and completes a task in a very short amount of time. UnFREEz didn't freeze, crash or pop up errors during our tests. User documentation is not available but this feature is not necessary, since getting around UnFREEz is extremely easy.

However, experienced users would probably be disappointed in the fact that UnFREEz doesn't let you configure any kind of advanced options. Nevertheless, it gets the job done and we definitely recommend it.
