Quality & Fidelity
Color accuracy is a priority in this conversion. Xonvert maintains data integrity across the format boundary. The output closely matches your original. File size after conversion depends on the content complexity and your quality settings. PST Outlook Data preserves all data losslessly, so output size depends on the content's inherent compressibility. Use Outlook Import/Export wizard for PST migration For the best results, start with the highest quality Gzip Compressed source file available.
This is a cross-category conversion from Archive (Gzip Compressed) to Email (PST Outlook Data). While these formats serve different purposes, Xonvert extracts the compatible data from your Gzip Compressed source and maps it into the PST Outlook Data format. Archive files typically contain compressing tar archives, while Email files are used for Outlook email backup. The conversion bridges these two domains, allowing you to repurpose your content across different workflows.
The GZ to PST conversion applies format-appropriate algorithms to ensure maximum data fidelity. Single-file compression only — unlike ZIP, cannot bundle multiple files
