7-Zip for Windows 10: Download, Install, How to Use
Compression tools are indispensable for users who want to reduce the size of their files and free up space on their hard disk. 7-Zip for Windows 10 is one of the best solutions available, making it easy to add old and unused files to archives that take up far less disk space.
7-Zip is one of the most popular archiving utilities on the Internet, thanks to the fact that it’s free and open source. You can use it both at home and at work without any costs, and it supports a wide range of archive formats to suit virtually any workflow.
How to download 7-Zip for Windows 10
You can download 7-Zip from the official website for Windows 10, older Windows editions, as well as Linux. While this article focuses on the Windows 10 desktop version, it’s worth noting that the official site now also offers a console build for macOS, so Mac users aren’t entirely without an official option. Just make sure to get the setup file that matches your operating system’s architecture type.
Choosing the right installer is straightforward once you know your system type. To check, go to Settings > System > About and look at the System type field. Then match your result to the correct download:
- 64-bit operating system, x64-based processor: Download the Windows x64 installer — this is the right choice for the vast majority of modern PCs.
- 32-bit operating system, x86-based processor: Download the Windows x86 (32-bit) installer.
- ARM64-based processor: Download the Windows ARM64 installer, designed for devices like Surface Pro X or other ARM-based laptops running Windows 10.
The official download page offers both a standard .exe installer and an alternative .msi package. For most home users, the .exe installer is the recommended choice — it’s quick, straightforward, and requires no extra steps. The .msi package is primarily useful for IT administrators and business deployments, where software is distributed to multiple machines through group policy or endpoint management tools.
You may also notice an Extra package listed on the download page. This is not a portable GUI version of 7-Zip for everyday use. It contains the console version (7za.exe), standalone DLL files, and plugin files aimed at advanced or developer use cases. Most users should simply grab the standard .exe installer and skip the Extra package entirely.
How to use 7-Zip for Windows 10
7-Zip gets automatically added to the Windows Explorer context menu as soon as you set it up on your computer so that you can quickly access its options.
If you’re wondering how to compress files with 7-Zip, simply select one or more files or folders, right-click, open the 7-Zip menu, and add the items to a new archive. The process is straightforward and takes only a few seconds, even for large batches of files.
It’s possible to create a new ZIP or 7Z file with one click. It will have the same name as the root folder and will be saved in the same spot. Otherwise, you can select Add to archive… from the context menu to explore more options.
You can ask 7-Zip to add and replace files, update and add files, freshen existing files, or synchronize files. Besides ZIP and 7Z, it offers support for TAR and WIM formats. However, you can open more types of archives with 7-Zip, including RAR and GZ files.
What formats can 7-Zip create vs. extract?
It helps to know exactly what 7-Zip can and cannot do with each format before you start. Here’s a clear breakdown:
Formats 7-Zip can both create and open: 7Z, ZIP, TAR, GZIP (GZ), BZIP2, XZ, and WIM.
Formats 7-Zip can only extract (read-only): RAR, ISO, CAB, MSI, DMG, VHD, VHDX, and many others. A common point of confusion worth calling out specifically: 7-Zip can open and extract RAR archives, but it cannot create RAR files. If someone sends you a .rar file, you’re covered — but if you need to create a RAR archive yourself, you’ll need a separate tool for that.
Two advanced features worth knowing about: First, 7-Zip can split a large archive into multiple smaller parts, which is useful when you need to share a big file through a service that has size limits. To do this, set a value in the Split to volumes field inside the Add to archive dialog. Second, you can adjust the compression level — ranging from Store (no compression, fastest) through Normal up to Ultra (smallest file, slowest). Bumping the level up is worthwhile when storage or transfer size matters most; dropping it down saves time when speed is the priority.
If you want to prevent users from accessing your archives without your permission, you can set password protection using the 256-bit AES military-grade security algorithm. This level of encryption is considered highly secure and is widely used in professional and enterprise environments.
7-Zip can also create self-extracting archives (SFX), compress shared files, delete files right after compression, and change the compression level to create even smaller archives, depending on what you prefer. These advanced features make it a versatile tool for both casual users and power users alike.
Is 7-Zip safe?
7-Zip has no history of bad behavior or betraying the trust of its users. Plus, there are no malware alerts reported by VirusTotal.
And you don’t have to worry about losing your files or creating backups when using 7-Zip to compress files or extract files from archives since the original items remain untouched. The application is designed to be non-destructive, meaning your source files are always preserved throughout the process.
Beyond VirusTotal’s clean bill of health, there are a few concrete steps you can take to make sure you’re getting the genuine, safe version of 7-Zip:
- Download only from official sources. Always get 7-Zip from the official 7-Zip website or the project’s official pages on SourceForge. The vast majority of safety concerns surrounding 7-Zip come from third-party download portals that bundle the installer with adware or other unwanted software — not from the official release itself.
- It’s genuinely free and open source — no strings attached. 7-Zip is licensed under the GNU LGPL and is free for both personal and commercial use. There is no registration required, no trial period, and no payment. If a site is asking you to pay for or sign up to download 7-Zip, it is not an official source.
- Verify the file before you run it. As a quick sanity check, confirm that the file name and version number on the installer you downloaded match what’s listed on the official download page. For extra peace of mind, the official site publishes hash values for its releases, which you can compare against your downloaded file using Windows’ built-in Get-FileHash PowerShell command.
Conclusion
7-Zip for Windows 10 is a terrific file archiving utility, one of the best in the business. It’s lightweight, easy to use, and offers support for popular archive file types.
The fact that it’s free only adds to its long list of advantages. 7-Zip is definitely worthy of becoming your go-to compression and decompression tool, surpassing even WinRAR in several aspects. Whether you’re archiving personal files or managing large datasets at work, it delivers reliable performance without costing a penny.
