🏆 Best File Compression Software for August 2021

Need to save some space on your computer? These file compression software tools compress and decompress files. With such tools, it will be easier to free up device space and make more for new projects.

What is file compression software?

Are your files slowing down your computer? You no longer need to buy expensive external storage devices—file compression software is all you need. This software eliminates redundant algorithms and reduces the number of bits and bytes to compress files. That way, you can keep your files and still enjoy your computer's optimal performance. 

Why do you need file compression software? 

File compression software doesn’t only reduce your file’s size, but it also helps speed up your computer. Plus, it protects your data. With all files going digital, you need the best way to store and send files easily yet safely. Luckily, file compression software gives you that and more. Here are a few more benefits of getting a file compression software that you should know. 

Maximize Computer Storage

The best file compression software reduces the amount of storage you use for your computer. It frees up valuable space on your hard drive and even web servers. It can even compress your document files for up to 90% of its original size! By freeing up your computer’s storage, you can make room for new files and spare yourself from buying a new storage device.

Send Files via Email Easily

File compression software makes file sending via email as easy as pie, especially since you can instan meet email platforms' file size limits. Instead of saving your files in external storage and handing it over to the recipient, file compression software compresses your files so that email platforms can accommodate them for hassle-free sending.

Speed Up File Sending

Another fantastic benefit of file compression software is that it helps speed up communication. Sending and receiving a large number of files is an incredibly slow process. The sender has to wait for the files to upload and the receiver for the files to download. File compression software helps reduce the time spent on both processes for quick file sending.

Backup Your Files

File compression software automatically backs up your files. When a large group of similar files have been compressed and stored, they are combined to make an archive file. Most operating systems compress archive files to make backups. That means you're not only compressing files for storage, but you’re also saving backups should your files get deleted or corrupted.  

Encrypt Your Zip Files

Another benefit of file compression software is that it encrypts your files. It lets you protect the zipped files you are sending from prying eyes. Once your zip file compression software compresses your files, you'll have the option to create a password for it. That way, only you, or the authorized people, can access it.

Create Self-Extracting Archives

A self-extracting file is a compressed file that has an executable or .exe extension. This type of file will extract itself from the archive on its own. File compression software eliminates the need to download special software just to remove the compressed files. It spares you from downloading additional programs on your device only for mere file access.

Transfer Files Quickly

File compression software also lets you transfer files quickly into another device. Instead of moving one file at a time, you can create a single compact folder that contains all your data. Just drag and drop it to the other device! If you're working on a project that uses multiple devices, transferring your files quickly will undoubtedly help speed up completion.

Improve File Quality

When files are sent over through the internet, they have a high chance of being corrupted when received. Data compression software helps you reduce the file size for easy send over. It also protects the files' integrity and quality. It ensures that they will be received in good condition no matter what type of operating system is used by the recipient.

Improve Web Page Accessibility

Another advantage of using file compression software is it makes your files accessible on a web page. It doesn’t only compress files for sending, but it also makes it easy to upload and access your files on any online platform! By creating compressed internet-friendly files, file compression software lets you collectively send and upload files seamlessly.

Increase Employee Efficiency

If you're a business owner, file compression software assures you of better employee efficiency. Since compressed files are easy to decompress, employees will not spend much time waiting for downloads to be completed. It ensures that they can quickly resume working and not disrupt the operation flow by just staring at the monitor, waiting for files to be saved.

Provide Better Customer Service

Some companies provide services through downloadable content. File compression software allows a fast downloading process, so customers can get what they paid for in no time. Customers will be spared from long waits and corrupted files. With just one file compression software, you ensure customer satisfaction for each transaction you make. 

Core features of file compression software

By using a combination of primary and hybrid features, file compression software creates a positive file sending and downloading experience. These features help make file compression software a staple for every computer user. Here are a few more fantastic features that will surely make you want to download file compression software.

File Compression

One of the most primary features of file compression software is file compression. It’s what most people look for when downloading the software. This feature reduces the size of the file for more accessible storage and sending. Even free file compression software offers this basic yet fantastic feature to users.

File Decompression

Most people think that file compression software only has compression features. However, most software has a two-way feature that also includes decompression. This feature lets the receiver download the compressed files and convert them to an accessible format. With just one click of the folder, all files will automatically be decompressed and opened. 

Multiple Archiving Format

File compression software also has a multiple archiving format feature that accommodates archiving of different file types. This feature groups your files depending on file format and creates archives for each. It will generate file backups and help you organize your file storage because you'll have all similar files in one folder for easy checking. 

Batch Compression

Another feature of file compression software is batch compression. Most service providers let you compress files in large batches. Some may even let you squeeze up to 10,000 files at a time. Some free zip file compression software has this handy feature, which is especially useful for compressing small folders in large quantities for easy bulk sending. 

Password Capability

When you're uploading files in the cloud for multiple user access, you want to protect your files from unauthorized access for sure. Luckily, the password capability feature has your back. Most file compression software online has this feature to encrypt your files. With this, you can put passwords on your file and only share them with authorized users to maintain confidentiality.

Fast Compression

File compressions software also has a fast compression feature wherein you can compress and archive large volumes of files in a matter of seconds. Instead of uploading them in an online drive one by one, you can compress your files quickly so that you can send or transfer them to another device instantly.

Compress in Same File Format

The same file format feature compresses your files in the same format you saved them initially. This feature helps you access your file easily because you don't need to download any converter to turn your files into their original format. Since you'll get your native format, you'll have no trouble working on existing projects. 

Image Optimization

Most file compression software lets you reduce your images’ file size without affecting its quality with the image optimization feature. The image optimization option crops, resizes, and compresses pictures using a photo imager, like a JPG file compression software. In that way, you can prepare them for archiving, sending, or internet upload.

Video Analysis

The video analysis feature combines different technology in compressing video files. This feature analyzes the quality of videos to identify the best compression tools to ensure that the files' quality will not be compromised. Most video file compression software also has a quality estimation to create the best quality for the available bandwidth.

Quality Control

File compression software's quality control feature ensures that service providers have reliable technologies to maintain QoS (Quality of Service) and QoE (Quality of Experience). Since several platforms offer file compression software, quality services are essential—that’s why service providers ensure optimal quality of services to keep their competitive edge.

Software Compatibility

Another fantastic feature of file compression software is software compatibility. Most service providers create their software to be compatible with different versions of operating systems. That way, you don't need to update your operating system to use file compression software. 

Easy Browser Integration

The easy browser integration feature lets you compress files directly from web browsers just by right-clicking. This feature spares you from downloading the files one by one and then compressing them afterward. With the easy browser integration feature, compressing online files is a piece of cake.

Types of file compression software

People have different needs when it comes to file compression. Luckily, there are different types of file compression software you can choose from. These types vary depending on the process of compression and file output. Here are the various types of file compressions software to help you choose the best one for you.

Lossy File Compression Software

With lossy file compression software, your files are compressed by throwing out data that are deemed by the system as unnecessary. This process tailors the file to make it smaller. For instance, in photos, lossy file compression software combines all nearby colors to reduce the file size. The changes, however, are so small that most people won't even notice it.

Pro #1: Easy to Use

Lossy file compression software is easy to use. Once you click “Compress,” you'll have your files in seconds. You don't need to watch tutorials or review a manual because you can compress your files with just a few steps. Plus, there is even compression file software free of charge you can try out before getting a paid software plan.

Pro #2: Supports Multiple File Formats

Another advantage of lossy file compression software is that it supports multiple file formats. You can use just one software to compress your documents, audios, videos, pictures, etc. You don't need to purchase another software because you can do everything within a single platform.

Con#1: Lower File Quality 

A significant drawback of lossy file compression software is the lower file quality. Since the software is throwing out deemed unnecessary data, you are losing some parts of your file. For instance, when images are compressed, you may see visible pixels due to the compression. This drawback may turn off people who are keen on details.

Con #2: Permanent File Data Loss

Once your files have been compressed by a lossy file compression software, whatever data the software throws out are lost permanently. After you decompress the file, it will only contain the processed files. If the quality becomes lower, you cannot bring it back to its original condition. Thus, securing an extra copy of the original files is essential.

Lossless File Compression Software

Lossless file compression software reduces the file size without throwing out any data. It works just by removing all redundant information in the file to keep all your data intact. This type of file compression software allows you to recreate the file precisely using a data algorithm while still reducing its size for storage or sending purposes.

Pro #1: High-Quality Files

Since lossless file compression software keeps all your data, you'll still have high-quality files at the end of the day. You don't have to compromise the quality of the file to store or send it. It’s the most reliable file compression software for work files, such as spreadsheets, since you can't just throw out any information from them.

Pro #2: Minimal Visual Changes

Because lossless file compression software only eliminates redundant information—everything is retained no matter what. For instance, when using a lossless JPEG file compression software, the software will just group them to reduce the size instead of combining colors. That way, you'll have minimal to none visual changes.

Con #1: Less Files Size Reduction

Since lossless file compression software does not quickly eliminate data, then the file size reduction is expectedly less than lossy file compression software. Most of the time, the file size reduction is only up to 60%. If you're trying to send out bulk files in high quality, this type of file compression software might not be the right choice.

Con #2: Long File Compression Process

Another drawback of lossless file compression software is the long file compression process. Since the algorithms' checking is more complex versus the lossy type, the process takes a little longer. Nevertheless, the final file's quality makes up for the longer compression time, that's for sure. 

Zip File Compression Software

Another type of file compression software is zip. This type uses the same technology as lossless file compression software but can collect multiple files in a single unit. Instead of compressing one file at a time, you can squeeze them all into a single folder in one click. If you are storing or sending a large volume of files, zip file compression software is the right choice.

Pro #1: Multiple File Compression

Zip file compression software can compress multiple files at a time. You don't need to compress each file manually. This type of file compression software is also useful in creating organized storage for all your files. Even with a zip file compression software free download, you can create individual zip folders for each project.

Pro #2: Fast Bulk Files Sending

Another benefit of zip file compression software is fast email sending for bulk files. Among all the file compression software types, the zip-type is the best option if you want to send a large volume of files via email. Because it creates an easily attachable file folder, it makes the process of bulk file sending an easy feat for every user.

Pro #3: Multiple File Encryption

Zip file compression software does not only reduce the size of files or lets you send bulk files quickly, but it also lets you encrypt essential files. Since files are sent in a zipped folder, you only need to create one password to protect your files. This multiple file encryption feature is especially useful for confidential projects.

Con #1: Problematic File Decompression

A significant drawback of zip file compression software is the problematic file decompression. You may not have any problem compressing and sending files. However, once you decompress your folder, there may be instances when some files will not be decompressed automatically, so you have to redownload the folder.
