GIF Optimizer

GIF Optimizer is a software utility that allows you to optimize GIF animations, in order to reduce their size.

This type of tool can come in handy the moment you are dealing with large amounts of GIFs which take up too much space on the hard drive.

The app comes with a user-friendly interface and intuitive layout. Loading a GIF can be done with the help of the file browser, since 'drag and drop' is not supported. Unfortunately, you cannot process more than one file at the same time.

From the 'Settings' area, you can make the app remove unused palette entries, move the colors from 'Locals' to 'Global', remove redundant pixels, and crop transparent images.

You can define a custom value for reducing colors (or set GIF Optimizer to automatically do this), as well as disable interlacing. After optimizing the GIF, you can preview the respective animation in a built-in player, in order to observe the original and changed item.

GIF Optimizer also displays the initial and output size, along with the percentage of saved space. If you are satisfied with the new results, simply save the optimized GIF to file, by specifying the filename and directory.

The application supports some keyboard shortcuts, has a good response time and quickly finishes a job. We have not encountered any difficulties throughout our evaluation; GIF Optimizer did not freeze, crash or pop up error dialogs. Thanks to its intuitive layout and overall simplicity, beginners can shortly figure out how to work with GIF Optimizer.
