File Media Renamer is a WordPress plugin that allows to rename uploaded files already and change their postname or slug-url. 
This plugin simply adds two fields in the wordpress media frame, namely the filename field and the postname field where in you can easily rename the files. As per current wordpress versions does not support or does not have a feature of renaming uploaded files so you either need to delete the file and re-upload it again or simply install this plugin and rename them in the media frame screen.
