Find password from open-protected pdf

I got an open-protected pdf from the server but also the decrypted pdf from the other place. The size of the open-protected file is 80MB that is slighter larger than decrypted one 76MB. Does it possible to extract the password by comparing two pdf files?

No, It's not possible. Passwords will be hashed by default using one-way hash functions like MD5, SHA1, SHA2 etc.

You can not determine the password just by using size or comparing the files.
