What is a BZ2 file?
A .BZ2 file is a Bzip2 Compressed File. The open-source compression algorithm was created by Julian Seward. It compresses a single file to save disk space. To compress multiple files, users often combine them into a .TAR archive first, creating a .TAR.BZ2 file. While most .BZ2 files are standard compressed archives, sometimes a file might be a disguised .RAR archive used for malware delivery. viewer.online/bz2 analyzes .BZ2 files to identify their exact format and creator software, shows which programs can open the file, and usually previews it.
How to open BZ2 files?
You can open .BZ2 files using standard archive utilities on most operating systems. On Linux and macOS, you can use the command-line tool `bzip2` or `tar`. On Windows, popular third-party tools are required to extract the contents. If you need to change the file to a more universal format like .ZIP or .TAR.GZ, we recommend using convert.guru.
Software and tools
Common software to extract .BZ2 files includes 7-Zip, WinRAR, and PeaZip. Unix-based systems include native support via the bzip2 utility.
Best practices and troubleshooting
Because .BZ2 only compresses a single file, you must check the extracted file extension to know what it contains. If you cannot open a .BZ2 file, it might be corrupt or intentionally disguised. Always scan downloaded archives with an antivirus program. If a program fails to extract the archive, viewer.online/bz2 can identify the actual format of your file.
Summary
viewer.online/bz2 directly opens and previews .BZ2 files in the browser, eliminating the need to install software or troubleshoot compatibility issues.
