Mbox Viewer is a native macOS application designed to open, search, and export emails from MBOX and EML archive files. It handles files of any size — from a few kilobytes to over 50 GB — without loading the entire file into memory.
Whether you're reading a Gmail backup from Google Takeout, performing email forensics, or simply browsing old email archives, Mbox Viewer gives you instant search, Gmail label support, conversation threading, and full export capabilities — all running locally on your Mac with complete privacy.
