PRIVACY & SECURITY

Privacy-First & Secure by Design

Your Emails, Your Privacy. 100% Local Conversion

Corporate emails hold all the intellectual property rights and the legal history along with the sensitive information about the individuals. In contrast to the online email converters that require you to upload your email files to their third-party cloud storage server, MacMister PST Converter is 100 percent non-networked.

100% Offline & Local Processing

It works solely through your Mac computer. After installation, you do not need an internet connection for extracting, viewing, and converting the PST files. Your personal and business emails, contacts, and attachments will never go outside your local system.

Strict Read-Only Extraction

No risk of corrupting the original PST file exists because the program uses a completely harmless and non-destructive technique to read and convert your email information without changing any byte of your original Outlook file.

Zero Data Retention Policy

None of your data is accessible by us. No data is cached, logged, harvested, or stored by MacMister, including emails, their contents, metadata, senders, or credentials. The software just reads from the source file and writes to the target format, then wipes the memory.

Apple Notarized & Signed

Say goodbye to any issues related to warping from the gatekeeper. The MacMister PST Converter is fully signed and notarized by Apple. That means that the software package is automatically checked by Apple for any malware, adware, or malicious code.

What They Say About PST Converter for Mac

Verified Software Reviews by our Top Clients

★★★★★

Our enterprise migrated 150+ users from Windows to MacBook Pros (M3 chips), and handling a decade’s worth of active and archived .pst files was a massive roadblock. I ran the MacMister PST tool on several 40GB+ corporate archives. It flawlessly converted the data into standard Apple Mail-compatible .mbox structures without a single memory leak or crash. Every inline attachment, distribution list, and sub-folder remained exactly where it belonged. Absolute lifesaver for IT departments.

I needed to convert thousands of old Outlook emails into searchable PDFs for a legal research archive. Other tools stripped out the original timestamps and email headers, which made them useless for compliance. MacMister successfully preserved the full RFC 822 internet headers (To, From, Cc, Bcc, and exact server timestamps) and embedded the original document attachments directly inside the PDF files. The custom file-naming options (Date + Subject) saved me hours of manual renaming.

I had a bunch of old password-protected PST files from my old office job but no longer own a copy of Microsoft Outlook on my iMac. I was skeptical, but the MacMister demo let me test the first 25 emails for free. It completely bypassed the password lock and accurately extracted the mailbox directly into my IMAP server configuration. The interface is self-explanatory—just load files, pick a format, and hit convert. No technical background required.
