Why need to clone HDD to SSD of different sizes?

Can I clone a 1TB HDD to a 500GB SSD?
Hello, all experts. I have a 1TB hard disk drive, but only 50GB used. Several days ago, I just got a 500GB SSD drive from my brother. So, i wonder if I can clone the 1TB HDD to 500GB SSD drive?Thanks a lot!

Compared with traditional mechanical HDD, the SSD drive is supposed to be better in performance. It can significantly speed up computer. However, the SSD tends to be smaller in capacity than the HDD at the same price level. So, many users want to replace their bigger HDD with smaller SSD drive by cloning. But is it possible to clone HDD to SSD of different sizes?
