Convert TAR.GZ to GZ — Free Online Converter

TAR.GZ is a tar archive compressed with gzip, bundling multiple files and directories into a single compressed stream. A standalone GZ file is simply gzip compression applied to a single file — no tar archival layer, no directory structure, just one compressed data stream.

Converting TAR.GZ to GZ extracts the tarball's contents and produces gzip-compressed individual files. This conversion is relevant when you need to distribute single files rather than a complete directory bundle, or when a downstream tool expects a plain .gz stream rather than a tarball. For single-file tarballs, this simplifies the format by removing the unnecessary tar layer.

Some tools and workflows specifically expect plain .gz input rather than .tar.gz. Web servers serving pre-compressed static assets (via nginx's gzip_static module) need individual .gz files per asset, not tarballs. Log analysis pipelines often process individual .gz compressed log files. Data processing workflows may expect single-file .gz input for streaming decompression.

For tarballs that contain only a single file, the tar layer adds unnecessary overhead — both in file size (512+ bytes of headers) and in extraction complexity. Converting to plain .gz simplifies the format for single-file distribution. For multi-file tarballs, the conversion produces the primary file as a .gz output.

The .tar.gz is decompressed by first stripping the gzip layer (DEFLATE decompression, CRC32 verification), then parsing the tar archive to extract file entries. For single-file tarballs, the extracted file is recompressed with gzip to produce a standalone .gz output. For multi-file tarballs, the primary content file is identified and gzip-compressed individually. The output .gz contains only the compressed file data with a gzip header and CRC32 trailer — no tar headers or directory information.
