How to Uncompress Files: Complete Guide for All Formats

Introduction
Compressed files are everywhere in the digital world. From software downloads to email attachments, compressed archives help reduce file sizes for easier sharing and storage. However, before you can use these files, you need to know how to uncompress or extract them.
In this comprehensive guide, we'll cover how to uncompress files of all popular formats including ZIP, RAR, TAR, 7Z, and more. Whether you prefer online tools or desktop applications, we've got you covered with detailed instructions for Windows, macOS, and Linux systems.
Common Compression Formats
Before diving into extraction methods, let's understand the most common compression formats you might encounter:
Format | File Extension | Characteristics |
---|---|---|
ZIP | .zip | The most common format, widely supported across all platforms |
RAR | .rar | Better compression than ZIP, but requires specific software |
TAR | .tar | Common on Unix/Linux, often combined with compression (.tar.gz, .tar.bz2) |
7Z | .7z | High compression ratio, open source format |
GZ/GZIP | .gz | Common on Linux/Unix systems, often paired with TAR |
BZ2/BZIP2 | .bz2 | Better compression than GZ but slower |
XZ | .xz | High compression ratio, newer format |
