Converting c image file back to lvlg binary format

I have lots if image resources in .c file format generated from Online image converter - BMP, JPG or PNG to C array or binary | LVGL

I was lazy and did not keep the original image resources for all images.

Now I want to start using filesystem and need them in binary format instead. Anyone have some code that does it in reverse order, i.e. convert .c file back to a binary file format for LVGL?

Just checking before I write this myself, it should not be to hard.

Thanks!

Implemented it myself in Python, was quite simple.
