Overview

What Is PST to EML Conversion?

PST to EML conversion takes a Microsoft Outlook PST file (which stores emails, calendar, contacts, and notes in one binary file) and exports each email as a separate .eml file. EML is a universal single-message format based on RFC 5322. Outlook, Windows Mail, Thunderbird, Apple Mail, and most email clients can open .eml files. Converting to EML is ideal for migrating from Outlook to another client or for archiving messages one per file.

Our free PST to EML converter processes on your device. You drop one or more .pst files, and the tool extracts all emails (including recovered deleted items when possible), then generates one .eml per message. All processing happens on your device; nothing is uploaded to any server.

Use cases include migration from Outlook to Thunderbird or Apple Mail, backing up Outlook mail as individual EML files, importing into Gmail or Office 365, and feeding messages into systems that expect one file per email. No Microsoft Outlook installation is required — the tool works on Windows, Mac, and Linux on any modern platform.
