Quality & Fidelity
Use gzip -9 for maximum compression on archival files For the best results, start with the highest quality PST Outlook Data source file available. Gzip Compressed is known for fast compression with good ratio, universally supported on Unix/Linux. This means your converted output will benefit from Gzip Compressed's core strengths. Meanwhile, the original PST Outlook Data's advantage of complete Outlook data: emails, contacts, calendar and tasks may not fully carry over, depending on Gzip Compressed's capabilities. Artifacts — unwanted visual or auditory imperfections — are minimized through Xonvert's tuned encoding parameters. Since Gzip Compressed is lossless, no artifacts are introduced during conversion.
