Fidelity When Converting LZH to GZ

Xonvert preserves embedded metadata (EXIF, XMP, ID3 tags, etc.) whenever the Gzip Compressed format supports it. Format-exclusive metadata fields that have no equivalent in Gzip Compressed are gracefully omitted without affecting the converted content. Quality in this conversion depends primarily on your source file. A high-quality LZH Archive input produces an excellent Gzip Compressed output. Since the target format is lossless, output quality matches your input exactly. LZH Archive encodes data using mathematical algorithms that preserve every data point. Gzip Compressed prioritizes exact data preservation. The conversion maps between these approaches intelligently.

Re-packaging files from LZH Archive to Gzip Compressed 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.
