Heap Size Modifier

Heap Size Modifier is a software application, built in Java, which provides users with a simple means of adjusting the heap size of a selected JAR item.

You can skip the installation process, as this program is portable. This means that it is not going to add any new items to the Windows registry and hard drive without your approval (as installers usually do), and it is not going to leave any kind of traces behind after its removal from the disk.

It is also important to mention here that you can take Heap Size Modifier anywhere with you and run it on any PC on the fly, by simply moving the program files to a USB thumb drive and clicking the EXE.

The interface you come across can only be described as plain and simple, as it encloses a small window, a button and a few boxes. It becomes quite clear that all types of users, regardless of their experience level, can work with it.

This utility enables you to temporarily modify the maximum and minimum heap size of a selected JAR file, by simply inputting the values to the appropriate boxes. As a result, the specified item is going to be launched with the newly applied parameters.

The “drag and drop” function is not supported, which means that you can only upload items with the help of the integrated file browser.

To wrap it up, Heap Size Modifier is a pretty small, yet efficient piece of software when it comes to changing the heap size of JAR file. It is dedicated to all types of users due to its overall simplicity, it does not hinder the computer’s performance and our tests did not reveal bugs or errors.
