Convert ZIP to TGZ — Free Online Converter

ZIP is the universal archive format built into every operating system, using per-file DEFLATE compression. TGZ is the compact-extension variant of gzip-compressed tar archives, using the .tgz filename required by Slackware Linux packages, Kubernetes Helm charts, and certain embedded system build tools. TGZ is structurally identical to .tar.gz but uses the shorter three-character extension.

Converting ZIP to TGZ transforms the universal cross-platform format into the specific .tgz format expected by Slackware's package manager, Helm's chart repository system, and embedded Linux toolchains. This conversion handles both the format change (ZIP to tar+gzip) and the extension requirement (.tgz rather than .tar.gz).

Slackware's installpkg tool recognizes packages by their .tgz extension — a ZIP file with identical contents would be rejected. Helm's chart packaging system distributes and installs charts as .tgz files exclusively. OpenWrt and Buildroot source caches store downloaded sources as .tgz by convention. Converting ZIP to .tgz makes the content directly usable by these specific infrastructure tools.

Beyond specific tool requirements, the .tgz extension simplifies automated processing. Shell scripts using glob patterns, MIME type detectors, and CI/CD pipeline rules that trigger on .tgz files will correctly identify the archive format. The single extension also avoids compound-extension handling issues that .tar.gz sometimes creates in path manipulation code.
