GroIMP is written in Java, which means it should follow Java's WORA-principle (Write Once, Run Anywhere) and should run on every Java-capable platform. GroIMP has been tested successfully on Unix and Windows platforms.

GroIMP 2.1.7 requires the installation of a Java runtime environment of version 17. This can be obtained from Oracle at www.oracle.com.

For a reasonably performant runtime behavior, at least 256 MB RAM and a 1 GHz processor are recommended.

The binary distribution of GroIMP is available on the gitlab release section as a zip-file, windows exe, or debian release.
