6 best file compression tools for Windows PCs

When it comes to sharing files, whether through email, cloud services, or even the classic flash drive, file size often matters. A smaller file not only conserves storage space but also meets the constraints imposed by email services. In this context, file compression tools become invaluable, and numerous programs are available to assist with this task. For those navigating the landscape of file compressors on Windows PCs, here’s a curated selection of some of the top options.

PeaZip

The cream of the crop

PeaZip stands out as a popular choice for file compression, boasting broad compatibility and impressive performance. In a recent test, PeaZip managed to compress a 1.63GB collection of files into a .7z format using LZMA2 compression, achieving a final size of 1.50GB in just over a minute. This efficiency places it among the fastest options available, while its encryption support and modern interface—complete with a dark theme—add to its appeal.

7-Zip

7-Zip is a household name in the world of file compression, known for its robust capabilities and speed. In a similar compression test, it reduced the same 1.63GB of files to 1.51GB in a mere 1 minute and 9 seconds. While slightly larger than PeaZip’s output, its rapid performance and ability to encrypt files make it a reliable choice, despite its somewhat outdated user interface.

WinRAR

A true classic

WinRAR has been a staple in file compression for years. Although it is a paid application, its free version offers substantial functionality without significant limitations. In a test, WinRAR compressed files into RAR format in just 38 seconds, but the resulting file size was 1.6GB, slightly larger than the original. For those prioritizing speed, WinRAR remains a lightweight and effective option.

Bandizip

A solid alternative

Bandizip presents itself as a solid alternative for file compression. While it may not outperform the leading options, it provides a modern user interface and a good balance of features. In testing, Bandizip took 2 minutes and 18 seconds to compress the same set of files to 1.51GB, landing it between PeaZip and 7-Zip in terms of efficiency.

8 Zip (Pro)

A more modern look

For users who appreciate a design that aligns with Windows aesthetics, 8 Zip is a commendable choice. Although not fully updated for Windows 11, it adheres to Windows 10 design principles and performs adequately. In testing, it compressed files to 1.58GB in 1 minute and 58 seconds, offering decent performance alongside visual customization options.

The built-in Windows compressor

Only on Windows 11 version 24H2

Windows 11 version 24H2 introduces a built-in file compression tool that, while slower than its counterparts, produces commendable results. In a compression test, it took 16 minutes and 25 seconds to create a .7z file of 1.50GB, making it the smallest output in the comparison. While not the fastest option, it serves as a practical solution for users who prefer not to install additional software.

Plenty of different options

This overview highlights some of the best file compressors available for Windows PCs. While alternatives exist, these selections provide a solid foundation for efficient file management. Users may also consider WinZip, a long-standing application, but caution against its potential bloatware issues.
