MZP Packer is a program designed to simplify the process of creating and packaging MZP format files used in the 3ds Max environment to install custom scripts and macros. The program provides a user-friendly graphical interface that allows:

Specify the script name, category, and tooltip to identify it.
Select the main script file (.ms) and icons (in color and alpha versions) in sizes 16x16 and 24x24 pixels.
Configure the use of only the button text instead of icons, if necessary.
Automatically create a file install.ms or it provides the opportunity to upload a custom version to automate the installation of the script in 3ds Max.
Create a ready-made MZP file that can be installed in 3ds Max via the "Customize" menu or by double-clicking.

In addition, the program includes a built-in PNG to BMP converter, which allows you to convert color and alpha channels of images to BMP format with support for various sizes (from 16x16 to 256x256 pixels), saving color images in 24 bits and alpha channels in 8-bit grayscale, as well as save them to your desktop. The program supports two interface languages — Russian and English — with the ability to switch. All actions are accompanied by a log in the right panel, where timestamps and operation results are displayed.
