How to convert XZ to 7Z

  1. Add your .XZ file - drop it in the box above or click to browse.
  2. Convert it to .7Z in a few seconds.
  3. Download your new .7Z file.

What to expect

  • Both .xz and .7z use LZMA2 compression at their highest settings, so the converted file will be similar in size to the original.
  • If your file is a .tar.xz, 7-Zip extracts the XZ layer first and leaves a .tar - you must extract that second layer before repacking as .7z.
  • .7z supports AES-256 encryption while .xz has none - converting is a good choice if you need to add a password.

Frequently asked questions

Does converting XZ to 7Z change the file contents?
No - the data is decompressed and recompressed losslessly, so nothing is lost or altered.
Will the .7z file be smaller than the .xz?
Probably not - both formats use LZMA2 and produce similar compression ratios on the same input data.
Can I do this on Windows without installing software?
Windows 11 can open .7z files natively but cannot create them; you need 7-Zip or NanaZip to both extract .xz and create .7z.
What is .tar.xz and how do I handle it?
A .tar.xz is a TAR archive compressed with XZ - extract both layers (XZ first, then TAR) before repacking the result as .7z.
