I have several Outlook PST files containing emails, attachments, contacts, calendars, and other mailbox data, and I need to convert them into different formats for backup and migration. The problem is that I don't want to depend on Microsoft Outlook during the conversion process.

I’m looking for a reliable PST converter that can:

  • Convert PST to EML, MBOX, MSG, PDF, CSV, HTML, DOC/DOCX, VCF, ICS, etc.
  • Process multiple PST files in batches.
  • Preserve the original folder hierarchy and email metadata.
  • Include email attachments during conversion.
  • Allow selective conversion using date-range filters.
  • Remove duplicate emails if required.
  • Preview emails and attachments before starting the conversion.
  • Import PST data directly into Gmail, Office 365, IMAP, Yahoo, Zoho, and other supported platforms.
I came across SysInfo PST Converter, which seems to cover most of these requirements. According to its product page, it supports 15+ output formats, batch PST processing, attachment handling, folder hierarchy preservation, duplicate removal, date filtering, and direct migration to platforms such as Gmail, Office 365, Google Workspace, and IMAP. It also works as a standalone application, so Microsoft Outlook isn't required for the conversion.

The workflow also looks fairly straightforward: add the PST file, preview the mailbox data, select the required folders and output format, apply optional filters, choose the destination, and start the conversion.
