How TGZ Handles SIT Data
StuffIt Archive already discards some data during compression. Converting to Tar Gzip Archive adds no further quality degradation since it uses lossless compression. Xonvert selects parameters that maximize quality for the target format. For professional use, quality assurance is critical. Xonvert's StuffIt Archive to Tar Gzip Archive pipeline has been tested against reference implementations to ensure output meets archive industry standards. Real-world quality depends on three factors: source file quality, format capabilities, and encoder settings. Xonvert optimizes the third factor automatically, but starting with the best possible StuffIt Archive source always yields the best Tar Gzip Archive output.
Re-packaging files from StuffIt Archive to Tar Gzip Archive archive format changes the compression algorithm and container structure while preserving all archived contents. File permissions, directory structures, and timestamps are maintained when supported by both formats. This conversion is useful when a recipient's system requires a specific archive format.
Important: Converting from lossy SIT to lossless TGZ does not restore previously discarded data. The output perfectly preserves your current file quality without adding further degradation, but quality lost during the original SIT encoding cannot be recovered.
