9 Best File Compression Software

File compression software programs work by compressing the existing files on a computer/device to save space and make sharing content easier both online and offline. The best file compression software comes at a low cost (preferably free), is able to compress files to a large degree and allows users to compress multiple files at one time. The main usage of file compression software is to reduce the size of a given folder or file that may be taking too much space. The major benefit of using compression software is more free space on a computing device and easier transfer of files either via a USB stick or online platforms such as Twitter, Facebook, Instagram and file-sharing services. Reducing the size of files also allows users to save data on mobile devices. File compression applications are typically reliable and safe to use. Such programs are important for people looking to reduce the size of files to avoid having to buy an HDD or upgrade the computer due to a lack of upgradeable storage options.

What to Know about File Compression Software

An image featuring a compressed file concept

The most important thing to know about file compression software is that not all file compression apps are made the same. Some focus on the compression algorithm, while others go for speed and security along with extensive format support. Most file compression software applications support the ZIP format. However, there are other (somewhat better) formats available as well. Since there is more than one compression format available, users should make sure to download a file compression software tool that can handle as many file compression formats as possible.

File compression software applications are fairly easy to use, especially if users stick to the popular ones mentioned above. In terms of usage, all file compressor applications require the user to download the app in order to select a file that needs to be compressed. After that, selecting a few options related to encryption, password and compression method, users only need to click a few buttons to complete the compression process.

File compression applications are fairly popular. WinRAR, one of the most popular file compression applications, has over 500 million users. WinZip has over 10 million downloads on the Google Play Store alone. ZArchiver, another popular file compression software tool, has over 100 million downloads on the Google Play Store. And WinRAR’s Google Play Store app listing shows over 100 million downloads.

How Does Compression Affect File Size?

Generally, compression reduces file size. Maximum compression percentages can reach 90% if the conditions are right. There is no loss of primary data when compressing files. Factors that affect the file size after compression include the compression format used, the file compression application used, the compression algorithms, the type of data and patterns in such data. Other secondary factors include the RAM, processing power, length of the document or video and, in the case of video content, video bitrate and video codec used.

Does File Compression Reduce Quality of the File?

Whether or not file compression reduces the quality of the file depends on the type of data that is being compressed and how the data is being compressed. For example, if the data type is an image, then compression can lead to reduced contrast, sharpness and some color.

Compression can sometimes be replaced with the word “zipping.” Zipping can be done either via lossless compression or lossy compression. Both do not cause a reduction in the overall quality of the data. Some of the details removed by compression are not important and/or perceivable by the human eye.

Note:

With that said, it is true that the reduction in quality is mostly insignificant in file compression. Users creating zip files of images may experience a reduction in the quality or size of the image.

Does File Compression Cause Any Harm to Files?

An image featuring a compressed ZIP file concept

Generally, file compression does not cause harm to files. The disadvantages of compressing files may or may not apply to the user depending on the type of file being compressed and the compression method.

Some types of file compression drain the computer of processing and memory resources. Moreover, compressed files take more time to open than regular files. Older computers without much resources to spare may even jam if multiple files are being decompressed at the same time.

File compression may not cause harm to files, but problems may arise if the user wants quick access to compressed files.

Indirect harm that may come to compressed files is when the user does not have the correct compression program. Certain compression programs support specific compression formats. If the user compressed the file with one program and then tried to open the file with another that does not support the first program’s compression format, then the file would remain inaccessible.

This is important:

To avoid most of the problems that come with file compression of any type, users should use reputable file compression software programs. Moreover, when sending compressed files to a contact, the link to the file compression software download page should also be sent to resolve any incompatibility issues.

What is the Fastest File Compression Software?

Currently, the fastest file compression software is 7-Zip.

Factors that affect file compression performance include the compression mode used, the type of file, compression ratio and compression format. Apart from that, the size of the file can also affect performance when comparing one file compression software with another. Some file compression tools perform faster on smaller file sizes and vice versa. Whether or not a given file compression program can take advantage of multi-core processors is another factor.

What is the Default Zip Program of Windows 10?

Windows 10 comes with a default zip program built into the system. All that users have to do is pick a file, right-click on the file and then select “Send to” and the “Compressed Zipped Folder” option.

The default zip program built into Windows 10 File Explorer does the job well, but there are other third-party file compression applications that offer better performance, higher compression ratios and faster speeds. Additionally, readers should keep in mind that the zip program in Windows 10 lacks extensive support for different compressions formats.

How to Change the Default Zip Program in Windows

The steps to change the default zip program in Windows are given below.
