Best PST to MBOX Converter for Windows & Mac: Fast, Safe, Accurate

The Best PST to MBOX Converter for Windows and Mac should be fast, safe, and accurate, preserving structure, attachments, and metadata while supporting batch jobs across platforms.

What to look for

Choose a converter that maintains folder hierarchy, keeps inline images and attachments intact, supports ANSI/Unicode PST, and runs natively on both Windows and macOS for seamless migration to Apple Mail or Thunderbird. Batch conversion, preview, selective export, and no file size limits improve speed and control without risking data integrity. Offline, desktop-based tools are preferred over free online converters for privacy and reliability with large mailboxes.

Recommended options

  • vMail PST Converter: bulk export to MBOX, preserves structure, works without Outlook; ideal for quick, lossless migration.
  • Vartika PST to MBOX (Mac): accurate, batch-ready, preserves metadata and attachments; supports all macOS versions.
  • inspire PST to MBOX (Windows): batch mode, selective conversion, fast speed, and no data loss claims.
  • Regain PST to MBOX: integrity-focused, previews, per-folder or merged MBOX, with logging and a free demo.
Why it matters

Manual methods are slow and error-prone; a robust converter cuts time, reduces risk, and ensures pixel-perfect mailbox replicas across clients.
