ImageJ is a public domain Java image processing program inspired by NIH image for the Macintosh. It runs, either as an online applet or as a downloadable application, on any computer with a Java 1.4 or later virtual machine. Downloadable distributions are available for Windows, Mac OS, Mac OS X and Linux

- It can read many image formats including TIFF, GIF, JPEG, BMP, DICOM, FITS and "raw"
- It supports "stacks", a series of images that share a single window
- It is multithreaded, so time-consuming operations such as image file reading can be performed in parallel with other operations
- It can calculate area and pixel value statistics of user-defined selections
- It can measure distances and angles
- It can create density histograms and line profile plots
- It supports standard image processing functions such as contrast manipulation, sharpening, smoothing, edge detection and median filtering
- It does geometric transformations such as scaling, rotation and flips (Image can be zoomed up to 32:1 and down to 1:32)
