    GZ: GZ is a single file compressed with gzip. Web servers, logs and databases use it heavily. Unlike ZIP, it holds only one file.

    TAR.XZ: TAR.XZ is a TAR archive compressed with xz (LZMA2), giving the best compression of the TAR family. Linux kernels and distributions use it.

    Frequently asked questions

    Will my files change when converting GZ to TAR.XZ?
    No. Archive formats are lossless, so every file is restored bit for bit and packed again.
    My GZ is password-protected — can I convert it?
    Yes. Enter the password when asked. You can also set a new password on the output (ZIP and 7Z).
    Is there a size limit?
    No fixed limit. It depends on your device's memory: several GB on computers, a few hundred MB on phones.
    Are my files uploaded?
    No. Everything runs in your browser with 7-Zip compiled to WebAssembly.
