Filesize reducing tools are highly useful programs that compress files so that they take up less data on HDD or SDD. There are also other reasons users would want to compress files.

For instance, compression software not only increases the available amount of space in your hard disk, but it also allows for faster file transfer. Having smaller files means that users can send more items through size-restricted sharing services.

In order to help you look for the ideal filesize reducing software for Windows 10, we compiled an up-to-date list of the best compression software currently available.

These applications earn their place in the spotlight for their flexibility, reliability, features, and more.

Which are the best filesize reducing programs for Windows 10?

Perhaps the most popular compression tool for Windows 10 is WinZip. It currently has more than one billion active users.

This tool is more than a simple compression tool as it also allows users to share, manage, password-protect, and backup files.

Furthermore, WinZip unzips all compression major formats, such as Zip, Zipx, RAR, 7z, TAR, GZIP, VHD, XZ, and more.

Other features include finding, opening, editing, moving, and sharing the files stored on PCs, networks, or cloud services. Not to mention the convenient integrations it has with Dropbox, G-Suite, or OneDrive.

WinZip also encrypts files to secure information and data and can create read-only PDFs and add watermarks to deter copying.

WinRAR is another highly popular compression software that has been around for a couple of decades.

It offers numerous features, but perhaps its most distinctive feature is its ability to create files in the RAR format. RAR is a powerful type of format that allows files to be compressed at extremely high levels.

WinRAR is the only official software that is capable of producing RAR files, but most compression software is capable of extracting RAR archives.

Besides, WinRAR can extract the following formats: ZIP, CAB, ARJ, ISO, 7-ZIP, UUE, GZIP, LZH, ACE, TAR, and much more.

Users will also be able to secure files with 256-bit encryption and password-protect them. WinRAR utilizes a unique algorithm to significantly increase the speed of the compression process.

As for its interface, WinRAR does not offer anything special. Yet, despite not being especially attractive, its interface is easy to use.



Files may be compressed to their minimum size with high-level encryption and safe sharing.


Users will be glad to know that 7-Zip is completely free, which makes it ideal for individuals on a budget. Despite being freeware, 7-Zip is still packed with features and has an outstanding reputation.

7-Zip is a highly flexible program, as it is capable of handling pretty much any type of compression format.

Furthermore, the file size reducer software offers its own compression format called 7z. This format is unique as it is specifically built to be able to handle massively sized files. According to its developers, 7z is capable of compressing files up to 16 billion gigabytes.

Unfortunately, the rate at which files are compressed or decompressed is rather slow compared to other popular file size reducer software for Windows 10. Thus, users with time-sensitive projects may not find this software to be ideal.

Aesthetically speaking, 7-Zip is definitely on the less attractive end of the spectrum. Nevertheless, reliability and efficiency are key when it comes to size-reducing software, and 7-zip is steady as a rock.
