Hello there,

My question is basically the thing in the topic, i would like to, if possible, know how in 2026 open a .grp file and maybie export in and out of a PNG to work with it in a convienient way.

Is it possible in this day and age? because i look around for some of the tools and didn't find any.

Also if possible i would like to know if i can get any tool than allows for this already compiled, if not, well, in that case i would appreciate directing me where i can deal with this in the simplest way possible.



Thanks

I haven't used it in a loooong time but

This should be the tool you need.

Thank you very, very much!

If anybody found this message and is looking for this program for linux, the link works so far as of today, and you must wine it to xp to make it run without issues.

To run it you will need the palets tho, and that can be obtained in this other application, it came with it:

and also you can wine it to xp to make it run without issues.

the tool you need by you mean is it something i need for converting or is that all i need to mod grp

This program converts .grp graphics for Starcraft and Warcraft II to bitmap format (.bmp) and back.

A good starting point would be to identify which software or game originally created the .grp file, since this extension can be used by different formats. Some older GRP formats have existing viewers or conversion tools, but compatibility depends on the specific format. If you can identify its source, it should be easier to find a tool that can open it and export its contents as PNG files. Hopefully someone familiar with that particular format can recommend a ready-to-use utility and save you the trouble of building your own converter.
