KMLReduce is a software tool that provides users with a simple means of compressing the size of all their KMLs according to your specifications.

The installation process is a piece of cake, as it does not last very long and it does not offer to download any products that are not actually necessary for the app to work properly. Once you are done with it, you come face to face with a simple GUI, as it only includes a few buttons and two boxes.

Furthermore, comprehensive Help contents are provided in a Notepad file, thus making sure that both power and novice users can handle it with great ease.

This program enables you to reduce the size of KML files by analyzing and compressing the polygon coordinates contained within them. In addition to that, it lets you adjust the tolerance value, as well as the minimum number of reduced polygons per shape. The latter basically implies that if the compressing process can generate smaller values than the ones input by you, the utility is going to use the original coordinates.

KMLs can only be uploaded using the built-in file browser, as the “drag and drop” feature is not supported. Once the operation is complete, you can view information such as original and reduced file size, source and output number of polygon coordinates and optimization percentage.

To wrap it up, KMLReduce proves to be a small, yet powerful piece of software. CPU and memory usage is low at all times and therefore, the compression process does not take a toll on the manner in which your PC runs. Tasks are completed in a reasonable amount of time, the interface is user-friendly and our tests did not reveal any errors, hangs or freezes.
