I recently switched completely to macOS, but I still have years of Outlook PST files from my old Windows system. I needed a solution that could archive those emails into searchable PDFs without installing Outlook or using a virtual machine.

After comparing a few options, I found the MacSonik PST to PDF Converter, and it seems to check most of the boxes. It supports both Intel and Apple Silicon Macs, so compatibility isn't an issue. What impressed me most is that it can process multiple PST files simultaneously without any file size restrictions, making it suitable for large mailboxes.

Another useful feature is the preview panel, where you can browse the complete mailbox structure before starting the conversion. That makes it easier to export only the folders I actually need instead of converting everything. The software also lets you To convert PST to EML files if you need a format that's easier to import into another email application later.

I also appreciate the flexibility of choosing whether attachments should be included in the PDF output. Combined with the date filter, duplicate email removal, and custom file naming options, it seems much easier to keep archived emails organized. The conversion report at the end is another nice touch because it shows exactly what was processed.

Security was another deciding factor for me. Since the entire conversion happens locally on the Mac, confidential emails never leave the computer. That gives me much more confidence than cloud-based converters.

Before buying, I'm planning to test the free demo, which converts up to 50 emails per folder. Has anyone here tried the Mac version? I'm particularly interested in feedback about stability, conversion accuracy, and performance when working with large PST files on macOS.
