How to Replace Icon in EXE or DLL File
Exe Icon Replacement
Whether you want to change the icons in the exe file or the default menu icons of your mobile phone, Resource Tuner will be your first choice. But first off, you should remember that there are more than just one icon inside any Windows executable file.
Icons are stored in EXE files in Icon Groups. Each Icon Group can contain multiple icon images, each with a different size and color depth. Common sizes include 16, 32, and 48 pixels square, color depths include 32-bit (24-bit with 8-bit alpha channel), 8-bit (256 colors) and 4-bit (16 colors).
That's how an Icon Group from our beloved Notepad looks like:
When changing icons and cursors, make certain that the replacement sources are the same size and have the same number of colors as the item to be replaced (e.g. a 16x16 4-bit icon cannot be replaced with a 32x32 8-bit icon).
If you keep getting a mismatch error when trying to change out an icon that looks the same size and bits, it only means the source icon is not the same color depth (24-bit and 32-bit icons look very much alike).
