    XZ: XZ is a single file compressed with LZMA2, giving excellent compression for one file.

    7Z: 7Z is the 7-Zip archive format. Its LZMA2 compression usually makes files 10–40% smaller than ZIP, and it supports strong AES-256 encryption including encrypted file names.

    Frequently asked questions

    Will my files change when converting XZ to 7Z?
    No. Archive formats are lossless, so every file is restored bit for bit and packed again.
    My XZ 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.
