Technical Quality Assessment
Artifacts — unwanted visual or auditory imperfections — are minimized through Xonvert's tuned encoding parameters. Since Cabinet Archive is lossless, no artifacts are introduced during conversion. Note that converting a lossy source to a lossless target cannot recover already-lost quality — it preserves the file as-is without further degradation. Use The Unarchiver (free Mac app) to extract SIT files On the output side, Extract CAB files with the Windows expand command Together, following these practices ensures the best conversion outcome between StuffIt Archive and Cabinet Archive.
Re-packaging files from StuffIt Archive to Cabinet 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 CAB 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.

StuffIt Archive is Classic Macintosh compression format from the pre-OS X era. It is primarily used for legacy Macintosh file archive and retro Mac computing. Developed by Aladdin Systems (now Smith Micro)
Will the conversion strip my EXIF or metadata?▼
Xonvert preserves metadata (EXIF, XMP, ID3, etc.) when the target CAB format supports it. You can optionally strip metadata in the settings for smaller, cleaner output files.
Does the conversion preserve metadata?▼
Xonvert preserves compatible metadata fields when converting between formats. Some format-specific metadata may not carry over if the target format doesn't support it.
Can I share the converted CAB file directly?▼
Yes. After conversion, you can download the CAB file and share it via email, messaging apps, cloud storage, or any other method you prefer.
Does converting SIT to CAB change the resolution?▼
