Here you can download an “all platforms” version of ImageJ, without a bundled Java or extra extensions.

Unfortunately, due to the ongoing transition from Java 6 to Java 8, this download of “plain ImageJ2” cannot currently be updated to the latest Java-8-compatible version. See the Java 8 page for details. For the time being, we recommend using the Fiji distribution of ImageJ to stay current with updates.

Distributions of ImageJ

These downloads bundle ImageJ with a curated collection of plugins pre-installed.



System requirements

ImageJ will run on any system that has a Java 8 (or later) runtime installed. This includes, but is not limited to:

  1. Windows XP, Vista, 7 or 8 with Java installed from
  2. Mac OS X 10.8 “Mountain Lion” or later with Java installed from
  3. Ubuntu Linux 12.04 LTS or later with OpenJDK 8 installed


ImageJ is distributed as a portable application. That means that you do not have to run an installer; just download, unpack and start it.


Source code

See the source code page for details on obtaining the ImageJ source code.
