What’s The Best File Compression Method? MakeUseOf Tests Zip, RAR & More

winzipthumb1   What’s The Best File Compression Method? MakeUseOf Tests Zip, RAR & MoreFile compression is an important and common task users frequently ask of their computers. Reducing a file’s size makes it easier to email or place on a flash drive. It also reduces bandwidth usage and the time required to move a file between PCs.

There are several popular ways to compress a file, but which is the best file compression method? To find out we’re comparing WinZip, WinRAR, 7-Zip and the native file .zip compression found in Windows 7. We’re going to compress the same files with each and measure how long compression takes and the size of the finished archive. Let’s see who comes out on top!

The Basics

These tests will be conducted using the native file format and default settings of each program. That means WinRAR will be compressing to .RAR, 7-Zip to .7z. and WinZip to .zip. The built-in Windows 7 compression utility also uses .zip.

Compression speeds are measured using a stopwatch. Final file sizes are measured using the “size” metric shown in the Windows Properties menu for each finished archive.

Compression Speed Test

To test compression speeds I’m going to throw each of these competitors through three different file compression tests. They are as follows.

Document test – A folder 65MB folder of Word, Excel and PDF files

App test – A 1.48GB folder containing the game Torchlight 2

Media file test – A 3.23GB folder containing .JPG and .MP3 files

Here’s a graph of the results.

compressiontest   What’s The Best File Compression Method? MakeUseOf Tests Zip, RAR & More

As you can see there’s a significant variance between the different software and a definite trend throughout. WinZip handily beat everyone by compressing the files into .zip format over twice as quickly as the next-quickest competitor.

Windows 7’s built-in .zip compression came in second, but there was a glitch. It turns out that it can’t compress files that have special characters. It could not complete our document compression test as a result. This may not be a problem for everyone but I find it annoying. It seems strange that the built-in Windows 7 compression utility can’t handle file names the operating system considers valid.

File Size Test

Though these results show a clear winner we have to take them in context of file size. Compressing to a smaller size takes longer, all other factors equal, so perhaps WinRAR and 7-Zip are the victors there. Let’s have a look.

filesizereduction   What’s The Best File Compression Method? MakeUseOf Tests Zip, RAR & More

Here we can see that the document test shows 7-Zip running away from the crowd. It reduced file size significantly more than WinRAR or WinZip.

In the larger folder size app and media file tests, however, there was a much smaller difference. 7-Zip was still the best, followed by WinRAR, but the advantage may be too small to justify much longer compression times. It only makes sense if you’re compressing a file that will then be downloaded many, many times (which may be why .RAR is common on file-sharing types).

Some readers may not find compression of any kind worthwhile for media files. These files handled are often already in a compressed format and don’t gain much benefit from being placed in a compressed archive.

Interface

While these four competitors all perform the same basic functions they’re different in how they go about their task.

Window’s built-in compression utility wins on ease-of-use because it just works. You can compress folders by right-clicking them and selecting the appropriate option from the menu. Folders compressed in.zip format open automatically. Functionality is an issue, however, as there are no options to speak of and the utility can’t compress files with special characters in their name.

winzip   What’s The Best File Compression Method? MakeUseOf Tests Zip, RAR & More

Next up is WinZip. It’s also easy to use because it looks like a bundled Windows app. It uses the ribbon interface and offers menus that mimic the design of those found in Microsoft software like Paint and Word. There’s also a lot of functionality. WinZip can connect with cloud storage providers and makes it easy to create self-extracting archives, use .zips for backups and etc.

The downside is price. The full version is $29.95 and you’ll need the full version to use the features which make WinZip stand out.

winrar   What’s The Best File Compression Method? MakeUseOf Tests Zip, RAR & More

That leaves WinRAR and 7-Zip. Both have an interface which provides a menu bar with large icons above a file explorer that can be used to find files you’d like to compress. It’s possible to start compression by right-clicking a folder or via drag-and-drop. And that’s about it.

7zip   What’s The Best File Compression Method? MakeUseOf Tests Zip, RAR & More

Honestly, though WinZip has the most impressive interface, the interface differences won’t matter much to most users. All of these options can compress folders via right-click, and they all automatically open archives, so you may never have to see the main menu. WinZip’s advantages are only meaningful to people who need to organize and compress numerous files on a regular basis.

Verdict

To be honest, it’s hard to hand down any definitive verdict. All of these competitors have strengths and weaknesses. They are also all perfectly adequate for the average user.

Since I have to make some recommendation, I’ll give preference to WinZip. It offered the quickest performance and has the best interface. Its compression performance could be better, but is good enough for most.

7-Zip is best for users who need maximum compression. It won the document compression test by a mile and was also the victor (by a small margin) in our other compression benchmarks. This is paid for in performance. 7-Zip was slowest across the board.

And then there’s WinRAR. This is the software I’ve always used and I probably won’t abandon it. Though it’s not the quickest, and it didn’t offer the best compression, it performed well enough in both areas. It’s also the easiest way to handle .RAR files – which are common on file-sharing sites. If that’s your thing .RAR is the only sensible choice.

Its unclear from your graphs which compression format is best, I would think that .rar and .zip are completely different and each have strengths also you didn’t really mention anything proprietary….
I would find it interesting if you could provide a test with many different special formats and tested which format did compression best for different types of files.

Can you add KuaiZip in the test? Just found out about it and it beat 7z in their proprietary .kz format

That’s the problem…the proprietary format means that others won’t be able to open the .kz files. Also sucks if you don’t have a way to get the program (say, after a system crash, and you need to un-.kz files to fix it). Dozens of programs can un-archive RAR, ZIP, 7Z, and other more common formats, including “portable” programs that can be accessed from a thumbdrive or other portable media, without installation.

good point, but I don’t actually plan to use .kz format, just need to know how does it compete with others when creating standard .zip format (and from the website, KuaiZip can create .7z format too).

The kicker for me is 7-zip is FREE, as in absolutely FREE. No advertising, No nag screen (WinRar, winzip ) no limitations on how many computers you can use in on (Winrar, winzip both limited) 7-zip as many as you want, FREE. No restrictions on commercial or business usage. No problem, with 7-zip it’s allowed – FREE. No registration needed (WinRar, Winzip). Just download and use. It also has a 64 bit version (also FREE) and a portable version (also FREE) And it also just works (as this article says) just as good as the rest that are not just FREE. – And, it will handle just about any compressed format you throw at it.

Hint – It’s also FREE

That’s the entire point. Winrar is NOT FREE. It is try before you buy – and if you don’t pay, then you are in violation of the terms you agreed to when you downloaded it. That makes you a pirate – (more guilt) Winrar is a fine program, almost as good as the absolutely FREE 7-Zip which has no nag screens at all because it is FREE. During installation, he does say he will accept donations though. And 7-Zip is a program that would be worth paying for.

7zip is free (open source), does the job well and extremely light on system resources. its compression speed is slow because it squeeze the files more as compare to its competitors. i have been using this tool for the last many years without having any problem. its highly recommended ….. cause open source rocks..!

Matt Charman

7zip is free, the other two aren’t. 7zip can also be integrated into your own applications, again free of charge. It’s a clear winner. If you’re after compression software, why would you want to pay for an application that isn’t as good at compressing files?

You can easily make 7zip offer the same compression as WinRar or WinZip, and it is then just as fast. It’s only slower by default because it compresses better.

Not trying to be inflammatory but I don’t think you understand the history of compression algorithms and that the ZIP format became the defacto standard as far back as the DOS days because of the number of users at the time. RAR and later 7z were new efforts to improve compression ratios – which is what the results showed .

I also don’t think you realize that both JPGs and MP3s are already compressed formats (lossy data compression). Some general purpose compressor will not even attempt to compress them. I half expected to see an attempt to compress MKV and WMV files using tools that are not meant for the job.

Sorry but this was a very badly written article with very little understanding of what each tool does, what each compression algorithm was trying to achieve (as a compromise between compression ratio and speed), what the ZIP format has done in recent years to stay competitive or that different data types require different tools.

It served only to confuse users not familiar with this field.

Default compression probably won’t do much. If you crank up the compression, they will compress a percent or two unless someone already natively compressed the heck out of them. In terms of trade-off, probably not worth the time to compress unless ever megabyte counts.

As I said…

“Some readers may not find compression of any kind worthwhile for media files. These files handled are often already in a compressed format and don’t gain much benefit from being placed in a compressed archive.”

It’s not a history article. Just a straightforward test with common (i.e. default) settings.

Not trying to be inflammatory, but…To be fair, read the article again.
In the article he did talk about media files (JPGs & MP3s) being already compressed formats.
He also explained speed Vs. compression ratio.

I really recomment/prefer 7-Zip because I have found it be very efficient even in opening archive of file extension that winrar or winzip can’t open. It has helped me a lot when I have tried to open file inside computer recovery dvd and even open archive done with Mac computer. So for me 7-Zip is really a must and stay on top of all others.

It handles over 150+ file formats,there’s context menu and drag & drop integration and comes in a portable flavor as well as a 64bit flavor you guys should give it a shot.I’m not sure how it compares in testing but in function it works just as good as the others listed above.

i can’t believe you recommended WinZip, really. and for $29.95(!). this article is bad and you should probably feel bad too.

in my opinion, what really matters in tools such as archiver is sufficiency. i want my program to handle compressed formats i need (zip, 7zip, rar, tar..) and don’t care if it can handle 150 additional formats (like .lbr) because i don’t use it. also i don’t want to convert anything to .pdf or buy something on cnet. this is hilarious!

on windows i would recommend 7zip because it’s stable, easy to use and open-source

A feature that should also be covered that is in WinRAR, the “recovery record”.

“RAR archive format supports a special type of redundant information called a recovery record. If an archive has a recovery record, it can be repaired even in case of physical data damage due to disk failure or data losses of any other kind, provided that the damage is not too severe. “

What I find is that on Windows you have to jump through hoops to get non-compressed archives like TAR and most people don’t have the applications to read them. Those are ideal for things like media files that are already compressed but they’re only commonplace on Unix systems in my experience.

This article was mildly disappointing, to be honest. Since first using PKZip under DOS to shoehorn files into a tiny hard drive, I have been using file compression software for a year or two now. BTW, the “PK” bit stands for Phil Katz, who wrote an international shareware bestseller and established an industry standard.

It is a rare example of computer users voting with their spending power for software on the basis of its reliability rather than its marketing. Nobody pays for a utility that doesn’t deliver, but everyone values stable software that works every time.

Paying for decent archive software makes sense if it generates or supports robust industry standards. When the built-in Windows archiver can’t manage its own filename standards, someone’s pulling your leg, mate. You should have just failed it on the spot.

The test line-up was thin and the tests were a bit rough and ready. In addition, I would have liked to see how today’s versions of Stuffit measures up against the competition, too. It was one of the original drag and drop archive applications and goes back 25 years (yes, twenty five) to 1987.

There is room for a bit of common sense with basic file sizes and it doesn’t take any rocket science to make a difference.

(1) A good way to save disk space and bandwidth is to use RTF files instead of DOC for basic text documents.

(2) Set the compression for PDF files when exporting and scale/crop pictures to the right size and resolution BEFORE putting them into a layout or document.

Re-compressing PDFs later just means that the software used to generate the original PDF either wasn’t set up properly or isn’t fit for purpose. Or both.

I have been using RAR for a long time, however I have switched over to 7-zip recently. It may be a little slower but one of its best features that you fail to mention is that it is open source software covered under the LGPL license and is free to use and to redistribute to your friends. All the rest are commercial software that you should pay for. There is one feature that both RAR and 7-zip share that you did not explain very well and greatly enhances their ease of use. They both can be embedded into Windows Explorers menu interface. When you browse to a file and right click on it then you can pick from the menu to “add it to an archive, extract it to a folder, or extract it here” options. This is almost as easy as using the native Windows 7 unzipping function.

I use both WinRar and WinZip. I got WinRar specifically to unpack .rar files, and when I saw how well it does all other formats, I just stuck with it. I used the “free” version of WinZip, so maybe I didn’t see the advantages of its speed, as the article pointed out. I have a copy of 7-zip, also because of its multiple-format capability. But I probably won’t use it now, as my compression needs don’t really fit the strengths of 7-zip, and WinRar is working well.

7 Zip is best for me

Where WinZip excels is its interface. It was designed to make it as easy as possible for the end user to work with ZIP files. WinZip came on the heels of the need for a Windows ZIP utility when PKWARE was still dominant. They never intended to go head-to-head with PKWARE in the best file compression. Even the early WinZip was worlds better than the Windows version of PKZIP.

Various formats including ARJ and RAR have been around since the DOS days, but ZIP was the ‘standard’ for file compression. PKWARE heavily marketed their product to become the ‘standard.’ It wasn’t necessarily the best in file compression but it worked well. In hindsight, it might have helped made things easier having a common format instead of 2-3 (maybe more) competing and incompatiable compression formats.

That said, the article is rather simplified which is okay for your basic end-user. Hands-down, for that audience, WinZip is the winner. As I said, their focus is all about the interface and that is both looks and ease of usage. However, a study of previous articles on archive utilities would quickly yield that these type of tests also include a mixed file type test too. Typically a user would be archiving a set of mixed file types. Some utilities performp better in these type of compressions than other (and arguably this is a better measure of the performance).

What is NOT noted is that there are a ivariety of options that most likely would affect the results shown. These utilities typically have different levels of compression that range from fast compression/minimal reduction to slow compression/maximum compression. Default compression types lie roughly in the middle of this range. Sometimes there are also compression types just for certain types of files.

Also, these aren’t your father’s Oldsmobile either. Some programs will attempt to recommend the best compression type based on the files you are trying to archive.

Finally, once again, this is yet another article that assumes that its audience are Windows users. WinZip and WinRar are ONLY for Windows. Articles should be more appropriately titled to note Windows.

The main thing I found weird in this article is that you mentioned the downsize of WinZIP’s cost, but didn’t mention the same thing for WinRAR (even though the screenshot clearly shows “evaluation copy”). In terms of licensing and nagging, WinZIP and WinRAR are the same – both are shareware with nag screen and costs a pretty buck.

Another thing which baffled me is that the test completely ignored the capabilities of “non-native” compression formats. For example, both WinZIP, WinRAR and 7-zip support compressed tar archives, and tar.gz routinely compresses better then zip (both in space and in speed) while tar.bz2 or tar.xz should give 7-zip a run for its money in space reduction.

if you want a better compression from 7-zip, you can use these settings.It’s not the fastest but pretty high file reduction ratio.compression and extracting may take some time and high cpu usage,but results in good compression ration for most files.

archive format 7zip
compression level ultra
compression method LZMA2
dictionary size 64MB
word size 256
solid block size 64 GB

I have been using WinRAR for years. One thing I’d like to pass on is I almost never compress files, I use the “Store” function in WinRAR instead of compressing files. Store is a way to collect the files and put them into a RAR file and not waste time compressing anything. HDD’s are so cheap now, to me it just makes sense to not compress anything, almost like an .ISO file. That, my friends, is another story. I think y’all get the picture.

And let’s not forget peazip. It’s a good all-rounder is open source and multi-platform.

I used to use the paid-for version of Winzip but I got fed up with their pointless regular upgrades – we are now Vista compatible, now Win7 compatible etc and started to feel like I was just an income stream to Winzip. Peazip is all I use now on all platforms.

That said, I only seem to use zip for transferring collections of files by email these days so maybe zipping is no longer a mainstream tool anyway.

A point that should be also taken into consideration is that 7-zip is the only program of the 3 that is free.

Thanks for the tests and the info. I use 7-Zip and will stay with it.
“bben” (in Comments) said it all perfectly.
By the way, what native file .zip compression found in Windows 7???
I have no native file .zip compression in my Windows 7 Home Premium. That’s why I download 7-zip.

first of all thanks for posting the article and testing the compression software’s but i would appreciate if a review i and tests are done for the ”freearc ” file compression software which i have been using for sometime now , in which i find it compresses much more better than any other software out there , and it fast in both compression and decompression of files in which i can compress a 1 GB file in few seconds and decompress it much more faster and it can open more files types then other software’s but the only drawback is it compresses in only one format which is .arc which cannot be opened by other software’s, but this is only a laymen’s ( like me) view, and also i would like if test are done for Uharc software also ,since it does the same performance as freearc but it compresses much more but it is very slow, so hope test and reviews will be done on this pretty good totally free software’s

I prefer 7-zip (and .zip), since it is free and fast when compressing to .zip.

If you prefer to/need to share full-size files of your photos but they are very “heavy” maybe have a look at Blubox [http://www.blubox.com/]. This program (freeware with ads, payware without) can significantly compress image files. Recipients can use the free Blubox Viewer.

As for general compression, I am a long-term user of 7-Zip. It may not be the fastest but it does all I need, except compress photos!

You forgot uharc, probably the most powerful archive format to date in terms of compression. It is a discontinued format, and has been for awhile but still to date the one that will give you best result, I tested it myself vs 7zip lzma 2, rar, zip, zipx, gzip, etc using variety of different file types, sizes and quantities.
