Binary Files Merge Conflict Issues

Hello All,

I am the new user of GitLab tool and recently trying with to deploy the same for my project. The issue is all the files within a project directory are of Binary types, and since there are multiple members in team who needs to take that project and work on, the issues of merging of Binary files are there. I used the inbuilt capability of GitLab with command “git mergetool” which shows up the difference in a files before we PUSH the changes in to the repository. These difference shown up here can not be readable by the user.
Please suggest any additional plugins, tool or other capability of GitLab using which this can be resolved and make GitLab as one of prominent deployable tool for version control for my team and the users.

Thanks, Rahul
