Fidelity When Converting TAR to SIT
Xonvert's conversion engine analyzes your TAR Archive source and selects the optimal encoding strategy for StuffIt Archive output. No compression by itself — commonly paired with gzip (.tar.gz) or xz (.tar.xz) Preserves Mac resource forks and file type/creator codes These implementation details are handled automatically by the converter. A/B testing confirms that Xonvert's TAR Archive to StuffIt Archive output is indistinguishable from reference-quality conversions produced by leading desktop software. The WebAssembly engine uses identical codec libraries. Tape ARchive — originally designed for sequential tape storage Developed by Aladdin Systems (now Smith Micro) These technical characteristics influence how quality is preserved during conversion.
Re-packaging files from TAR Archive to StuffIt 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.
Compression trade-off: Your lossless TAR source retains all original data. Converting to lossy SIT will reduce file size substantially, but some data is permanently discarded. Use the quality slider to balance file size against fidelity.
