Is there easy way to verify two dlls equality?

I have 2 dlls and 2 pdbs.

I want to verify their equality. Meaning they have the same content (no nessesarly same creation date)

Is there any easy freeware tool to do so?

The easiest way to compare files to ensure the are identical is to you the file compare tool that comes with Windows. From the command window

fc /b file1 file2

If by equality you mean same contents, you could calculate the SHA1 checksum of both files and compare the two hashes:

using(var cryptoProvider = new SHA1CryptoServiceProvider())
{
    byte[] buffer = File.ReadAllBytes("library1.dll");
    string hash = BitConverter.ToString(cryptoProvider.ComputeHash(buffer));
}
