Quick Summary

What is PST File Converter?

PST (Personal Storage Table) is Microsoft Outlook's proprietary file format for storing emails, contacts, calendars, tasks, notes and journals. PST files are used for local storage, archiving and backup in all versions of Outlook.

The 4n6 PST Converter allows you to open PST files and convert them to formats compatible with other email clients like Thunderbird (MBOX), Apple Mail or archive them as PDF documents, EML files or other standard formats.

Why convert PST files? You might need to switch from Outlook to another email client, create searchable archives, extract emails for legal discovery, backup without Outlook or share emails with people who don't use Outlook.

The converter works without Microsoft Outlook installed and supports both Unicode (newer) and ANSI (older) PST file formats, including password-protected files.
