Technical Quality Assessment

When converting from StuffIt Archive to LZH Archive, the conversion is lossless, meaning every bit of data is preserved exactly as in the original. StuffIt Archive already discards some data during compression. Converting to LZH 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 LZH Archive pipeline has been tested against reference implementations to ensure output meets archive industry standards.

Re-packaging files from StuffIt Archive to LZH 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 LZH 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.
