Size of project decreased while cloning from old repository to the new one

Hello All!
Looking forward for your support.
I am trying to clone from old repo to new, everything is being copied correctly, all branches and files and on the place, but the size is reduced, previously It was 14.5 MB but now 12 MB, is it normal that the size is reduced or there may be some issue?

Thanks in advance!

When cloning the logs, artifacts, packages etc are not cloned.
Do you really just look at the repository size or is the 14.5 MB the project size?
