Project tool window | context menu of two selected folders | Compare Two Files
This dialog is displayed every time you explore differences between files (local history for folders, recent changes, version control, local files and their versions on a remote host, or just comparing files). So doing, you can compare files of any types, including binaries.
You can also open the difference viewer without running IntelliJ IDEA. This is done through the following command:
<path to IntelliJ IDEA executable file> diff <path_1> <path_2>
where path_1 and path_2 are paths to the files in question, which can be of various types, including jar.
The differences viewer provides a powerful editor that enables code completion, live templates etc.
