TGZ is the short-extension variant of gzip-compressed tar archives, using the .tgz filename originating from 8.3 DOS filename conventions. The format is structurally identical to .tar.gz but the .tgz extension is specifically used by Slackware Linux packages, Kubernetes Helm charts, and embedded system build tools. 7Z uses LZMA and LZMA2 algorithms from the 7-Zip project, delivering substantially better compression ratios than gzip DEFLATE.
Converting TGZ to 7Z recompresses a Slackware package, Helm chart, or embedded system tarball using the more efficient LZMA2 algorithm. This is valuable for cold-storage archiving of package collections, where the 20-40% size reduction compounds across hundreds or thousands of archived .tgz packages.
Package repositories and artifact archives accumulate large volumes of .tgz files over time. Slackware mirror operators, Helm chart museums, and embedded firmware archives may store thousands of .tgz packages. Recompressing these to 7Z for cold storage can reduce the total footprint by 20-40%, translating to meaningful savings on cloud storage costs (S3, GCS, Azure Blob) at scale.
7Z's solid archive mode provides additional savings when archiving multiple .tgz packages together. Because packages from the same project often share significant content (libraries, headers, documentation), solid compression exploits this cross-file redundancy for compression ratios that individual .tgz files cannot achieve.
The .tgz file is decompressed by reading the gzip DEFLATE stream and verifying the CRC32 checksum. The resulting tar archive is parsed entry-by-entry, extracting all files to a temporary directory preserving the complete hierarchy. The extracted file tree is packed into a 7Z archive using LZMA2 compression with solid mode and automatic dictionary sizing. For bulk conversions, multiple .tgz packages can be combined into a single solid 7Z archive for maximum cross-package compression benefit.
Entirely lossless. Every file from the .tgz is extracted in its original form and repacked into 7Z with byte-for-byte identical content. Package metadata files (slack-desc, Chart.yaml, etc.) are preserved exactly. The 7Z output will be 20-40% smaller than the .tgz input while containing identical data.
