15 Best Free GIF Compressor Software For Windows

Here is a list of the best free GIF compressor Software for Windows. These freeware let you reduce the size of animated GIF files so that they take less space and load faster on websites. Some of these software incorporate lossy compression technique, while others incorporate lossless compression. The GIF files can be compress in a number of ways, like:

• Reduce the resolution.
• Reduce the aspect ratio.
• Reduce the number of colors.
• Reduce number of frames

While these can be done in a number of image editor software as well, but those software don’t work very well for GIF files.  If you try to compress GIF files using image editors, you are just displayed with a single frame of the animated GIF. The software included here keeps the nature of your GIF files intact.

My Favorite GIF Compressor Software:

Among the software enlisted here I like PhotoScape the most. It is due to the reason that along with compressing the GIF file it also shows the frames of the GIF file, which can be deleted and also new frames can be added. You can also modify the GIF files using this freeware.
