Need to clone 500GB HDD to 256GB SSD

“To have better experience in booting operating system or loading programs, I have purchased a 256GB Toshiba Q Series Solid State Drive and I have a 500GB HDD with only 129GB used. Now, I want to replace my existing 500GB HDD with the SSD.

But I’m really unwilling to make a fresh install of Windows and other applications on SSD. Thus, I want to clone 500GB HDD to 256GB SSD. I know that it is available to clone hard drive to a larger drive. But is it possible to clone a larger HDD to a smaller SSD without data loss? And how?"
