Resource Hacker is a freeware utility to view, modify, rename, add, delete, and extract resources in Windows executables and resource files (*.res).

It incorporates an internal resource script compiler and decompiler and works on all Windows operating systems.

Viewing Resources: Cursor, Icon, Bitmap, GIF, AVI, and JPG resource images can be viewed. WAV and MIDI audio resources can be played. Menus, Dialogs, MessageTables, StringTables, Accelerators, Delphi Forms, and VersionInfo resources can be viewed as decompiled resource scripts. Menus and Dialogs can also be seen as they would appear in a running application.

Saving Resources: Resources can be saved as image files (*.ico, *.bmp, etc. ), as script files (*.rc), as binary resource files (*.res), or as untyped binary files (*.bin).

Modifying Resources: Resources can be modified by replacing the resource with a resource located in another file (*.ico, *.bmp, *.re, etc.) or using the internal resource script compiler (for menus, dialogs, etc. and/or). Dialog controls can also be visually and resized by clicking and dragging the respective dialog controls before recompiling with the internal compiler.

Adding Resources: Resources can be added to an application by copying them from external resource files (*.res).

Deleting Resources: Most compilers add resources in applications that are never used by the application. Removing unused resources can reduce an application's size.
