View PST files without Outlook or conversion
Sometimes you just need to look inside a PST file — read a specific email, retrieve an attachment, or check what an archive contains — without going through a full conversion process. The PST Viewer opens PST files directly on your Mac, Windows PC, or Linux machine, letting you browse and search the contents immediately. No Outlook required, no email client needed, and no data uploaded anywhere.
