Most of us all have auto media download option enabled which downloads everything and eats up all the space we needed. WhatsApp only stops auto download when you have no storage space left. WhatsApp Cleaner will automatically deletes files which are X-Days old.

Caution: If you ever receive or send any important photo/video/doc or animation please make a backup of it somewhere safe like i.e. GDrive or Dropbox. I will not be responsible if you lose any important file.
