What is Gzip extract?
Gzip is the lossless compressed format defined in RFC 1952. A .gz normally restores one byte stream. A .tar.gz or .tgz restores a TAR archive whose file and directory entries can then be listed and extracted. This tool handles both layers locally.
How to use this tool
Open .gz, .tar.gz, or .tgz and review the detected contents. A raw Gzip result provides one restored file; a Gzip-compressed TAR provides multiple entries and folders. Check names and paths before extracting. Use Gzip Create for the reverse workflow.
Choosing the right format
Gzip does not preserve a hierarchy by itself; TAR does. RFC 1952 permits optional filename metadata, but it is not a substitute for a multi-file archive directory and may not be present or portable.
Important limitations
Gzip’s CRC-32 detects accidental corruption, not malicious modification. Untrusted archives may expand greatly or contain unsafe TAR paths. Review entries, avoid overwriting important files, and use sandboxed native software for large or suspicious archives.
Frequently asked questions
Why can another program not open the result?
The extension may be misleading. Valid .tar.gz must first decode as Gzip and then as TAR; plain .gz has no TAR entry list. Corrupt, truncated, Zlib, and ZIP input are different formats.
Are my files uploaded?
No. The archive is read, decompressed, and prepared for download locally.

The archive is processed locally and is not uploaded.
