Only for Mac

$4.99

Mac

Open, convert and extract EML, MBOX, PST and winmail.dat email archives on your Mac — fast, private, offline. Email Converter turns Mbox and ZIP email archives into individual EML files that open directly in Microsoft Outlook, Apple Mail, or any standard email client — on your Mac, completely offline. Whether you are migrating from Gmail, processing a legal export, or converting an archived mailbox from another mail client, Email Converter handles files of any size using a streaming parser that keeps your Mac responsive throughout. HOW IT WORKS Drag your Mbox or ZIP file into the app. Email Converter reads each message sequentially and writes a separate EML file for every email. The output folder contains one file per message — named with the sender and subject — ready to open with a double-click. KEY FEATURES Blazing Fast Process 100,000+ emails in minutes. A 9 GB archive that would take hours to manually sort is fully converted in under ten minutes on modern Mac hardware. Memory Efficient The streaming parser keeps peak memory usage below 500 MB even for the largest archives. Your Mac stays responsive and your other apps keep running normally throughout the conversion. Privacy-First Email Converter works completely offline. No email content is sent to any server, parsed by any cloud service, or transmitted anywhere. Your messages never leave your Mac. Auto-Deduplication Email archives from multiple exports often contain duplicate messages. Email Converter automatically identifies and removes duplicates so each unique message appears exactly once in the output. Attachment Preservation Every PDF, image, spreadsheet, contract, and embedded file in the original email is correctly extracted and included in the EML output file. Nothing is lost. Real-Time Progress A live progress indicator shows the conversion count, current email, elapsed time, and estimated time to completion. COMPATIBLE INPUT FORMATS • Standard Unix Mbox files (single-file mailbox archives) • Apple Mail .mbox packages (folder-based archives) • Thunderbird exported Mbox mailboxes • Google Takeout Mbox exports (Gmail and Workspace) • ZIP files containing one or more Mbox archives OUTPUT FORMAT Each converted message becomes a standard EML file — the native format accepted by Microsoft Outlook, Windows Mail, Thunderbird, and all major enterprise email clients. Files are named using sender and subject for easy browsing without opening an email client. WHO USES EMAIL CONVERTER Legal and compliance teams: Convert Gmail Takeout archives or client email exports into Outlook-compatible EML files for eDiscovery review, regulatory audits, or litigation support. IT administrators: Migrating an organisation from Gmail or another platform to Microsoft 365? Email Converter converts the export so every user can import their full email history into Outlook — with all attachments intact. Records managers: Bulk email archives received as part of data subject access requests, regulatory submissions, or records transfers are converted into individually accessible EML files in minutes. Forensic analysts: Process email evidence archives offline with a deterministic conversion that preserves every header, body, and attachment exactly as received. SYSTEM REQUIREMENTS macOS 14.0 Sonoma or later. Supports Apple Silicon and Intel Mac. One-time purchase — no subscription, no recurring fees.
