About gzip
gzip (.gz) compresses a single file with the Deflate method. It is standard on Linux and on the web, where servers use it to compress pages.
Compressing single files such as logs and database dumps, and as the outer layer of .tar.gz archives.
A .gz file holds one file only; to bundle several files, they are put into a TAR archive first.
Convert gzip to xz online free, no account required — xz is a single-file compressor using LZMA2.
Change gzip to xz without losing quality — convert gzip to xz free in your browser.
Why does my .gz file refuse to open as an archive? Gzip holds exactly one file, not a folder of files like ZIP, so tools that expect an archive listing find nothing — decompressing first reveals the single file inside.
About xz
xz compresses a single file with the LZMA2 method and usually gives the smallest result of the common single-file compressors.
Linux packages, kernel images and large data files.
It holds one file only and needs a lot of memory at high compression levels.
Why convert a file to XZ? When the smallest possible file matters most: LZMA2 beats gzip and bzip2 on almost any data.
What changes when you convert gzip to xz
- No data is lost: every file in your gzip archive is packed into the xz archive byte for byte, with its name and folder.
- Your gzip archive is unpacked and its files are packed again into a new xz archive; file names and folders are kept, and the gzip file itself is not stored inside.
- A xz file holds a single file, so when your gzip archive contains several files they are first bundled into one TAR archive inside the xz.
Settings you can change
