If you use the /t option it will truncate Android images or ELF files to the actual active size.
In the old days an Android image was 12-20 MB, now more like 30-50 MB. Usually the partition itself is about 100 MB.
If you are dealing with stock images there are AVB footers at the end so instead of saving 30 MB you have to save all 100 MB (or whatever). If your image is Magisk it does have signatures after the "normal" active area but you don't really need them.
Sounds complicated? It is.
