Drop XZ files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.
Press Convert. There is nothing else to set. The work happens in this tab.
Save the 7Z, or download everything as one ZIP if you converted several files.
The XZ to 7Z converter is part of this page and runs inside your browser. Your compressed files are never sent to ToAny or to anyone else.
Nothing has to travel to a server and back, so the conversion starts the moment you press Convert, even on a slow connection.
No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.
XZ holds one file only, compresses slowly and is less widely supported than ZIP. 7z usually compresses tighter than ZIP. XZ is at home in software distribution where download size matters; 7Z is the usual choice for the smallest archives.
A password-protected archive is refused, since its contents cannot be read without the password. A .xz file holds one file and no folders; that file is unpacked as it is and then repacked into the 7Z.
XZ squeezes a single file with the LZMA2 algorithm, producing noticeably smaller files than gzip at the cost of more time and memory when compressing. Linux kernel sources and many distribution packages are shipped as .tar.xz.
Opens in Linux, 7-Zip and most archive utilities

The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the XZ file, press Convert and save the 7Z. There is nothing to install.
Yes. An archive can be up to 500 MB, unpack to at most 1 GB and hold up to 50,000 files; beyond those limits the page says so. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
