GIF images are a great way of how you can for example create animations from funny video clips. In fact that’s pretty much the main use of this image format. Problematic thing about it is the fact that usually they are very big. Here’s how you can compress and decrease the size of GIF images with GIF Optimizer.

GIF Compression and Optimization with GIF Optimizer:

Open images by clicking on the File option in the top left corner or by clicking on the Open option down below at the bottom of the window. Once that you select the GIF animation that you want to edit, it’s gonna be opened and displayed in the left preview window. Media player controls can be used in order to preview the GIF animation.

GIF Optimizer optimization settings

By clicking on Settings button in the bottom right corner you should be able to see all the previously mentioned options and turn off or on the ones that you want to use. Color reduction can be automatic or manual if you want. When you’re done click on Back.

Main menu should pop-up and to start the optimization you just need to click on the Optimize button. How long the optimization take of course depends on the size of the image, but it shouldn’t be long. Small report will be available to see how much the image was optimized.


GIF Optimizer is very effective, but note that the new size of the GIF animation after it’s compressed and optimized might not be very different from the original. Effectiveness of the optimization depends on what kind of image is optimized. According to the developer, images can lose up to 90% of their size, so give it a go and see just how effective GIF Optimizer will be for you. Click here to download GIF Optimizer.
