Why Does File Size Changed After Being Copied From NTFS To HFS?

I want to use my external hard drive on my MacBook running both macOS and Windows, but I have no liking to any third-party software. So I copy files from the NTFS drive and make changes then switch to Windows and sync these changes to NTFS. But I find that the file size changes after the files are copied from NTFS drive to HFS partition, I wonder wha's going on?

Good day, my friend. Actually, the same file on two different volumes might use different disk space because a disk is divided into sectors that are certain minimum sizes, So, if disk-1 has 512-byte sectors and disk-2 has 1024-byte sectors, a file containing only 10 bytes will take up twice as much space on disk-2 as it does on disk-1, even if the files are identical.
