I wonder if you have checked with you Library at COMSATS University Islamabad. I see that you may have access to the Journal Citation Reports through an arrangement with Lancaster University. Your Librarian will know. There is no other website apart from JCR, but there are other measures of journal performance. Check here for more information [ http://ambulance.libguides.com/blog/journal-rankings-citescore-data-released-from-scopus-for-2017 ]. In general journals will publish their Impact Factor on the Journal home page as it is a key part of their marketing.
Alternatively, you could check the impact of a journal in Scimago which is not the same as the WoS impact measure, but still gives you an indication on the quality of the journal. The SCIMAGO is open freely on the net.
