What is a LZ file?
The .LZ file extension is most commonly an Lzip Compressed File. Lzip is a lossless data compression tool based on the LZMA algorithm. System administrators and developers use it to shrink large data files, software packages, and backups. However, .LZ has multiple possible meanings. Sometimes, .LZ files are renamed WinRAR archives, Nintendo LZ77 compressed game assets for the 3DS, or firmware update packages for set-top boxes. Because the extension is ambiguous, we recommend using viewer.online/lz to identify the actual format of the user's file.
How to open LZ files?
On Linux and macOS, users typically open an Lzip Compressed File using the Lzip command-line utility or the standard tar command. On Windows, you can use third-party archiving software like PeaZip or 7-Zip. If the file is actually a renamed RAR archive, WinRAR is the best tool. For Nintendo game assets or hardware firmware, specialized modding or flashing tools are required.
File conversion
Sharing compressed archives with non-technical users can be difficult if they lack the right extraction software. We recommend file conversion to sensible target formats on convert.guru. You can easily convert .LZ files into standard .ZIP, .7Z, or .TAR.GZ archives for better compatibility across different operating systems.
Summary
viewer.online/lz analyzes .LZ files to identify their exact format and creator software, shows which programs can open the file, and usually previews it. viewer.online/lz directly opens and previews .LZ files in the browser, eliminating the need to install software or troubleshoot compatibility issues.
