Most Compression format


Question

I always enjoy flogging a dead horse!

Depends on the content of the file you're compressing... I'd say uharc for media files, and 7-zip for general stuff. but they aren't too common, so your overall best bet is probably rar files, like coroner said.

It depends on the files you are compressing. Try them out yourself with some files and see for yourself.

The best format in my opinion is RAR, there are other formats out there that can compress better (albeit only a tiny bit better) but RAR has so many powerful options such as spliting archices into multiple files, built in recovery records (similar to PAR files), compression profiles, archive authenticity verification and excellent SFX modules (GUI and DOS based for example). Also RAR is the most used format on the web these days.

What saint dark said.. 7-zip is really good but its slow. The version of the client I have seems to forget to release memory too, so after compressing a few files I find I need a restart.

Rar is nice though. Fairly quick and decent compression. Ace also seems nice, though I've not done anything with that myself.

,Nov 26 2003, 23:02] the 7-zip format compress better, but only 10% better than rar so that doesnt matter considering that 7-zip is extremely slow at compressing and de-compressing

Very true :yes:

I recently looked at using 7-Zip at work instead of WinZip however everyone agreed it is cheaper to use winzip because of the time saved vs. compressed size. Employee time is A LOT more expensive than a few KB (or MB in extreme situations).

In the end they went for WinRAR because of the 100% ZIP compression (so customers that still use WinZip are not affected) and because of the SFX being built in (something that doesnt come with WinZip for commercial use!).

WinRAR is easily the best because it gets excellent compression levels and is very quick. Also I think the RAR Vs 7Zip levels are actually about 3-7% not 10% (well maybe with some examples). However I have compressed loads of things that RAR gets smaller than 7Zip and the WinRAR UI is excellent (7Zip's is awful at the moment!)

Just a quick example...

I had 5 txt files which are 47.9KB in total.

in 7-Zip they are compressed to 16.5KB

in RAR they are compresse dto 13.5KB

in 7-Zip SFX they are compressed to 85.0KB

in RAR SFX they are compressed to 64.5KB

WinRAR wins :D

woohoo, try compressing your entire drive's contents and see which is smaller (Y) text files compress really well anyway, and two tests is hardly enough to declare a winner...

God, I can't stand it when people jump on the "yeah, me too" bandwagon when they hear some propaganda about new software supposedly being the be all / end all for one certain thing.

Do your own testing before jumping in and saying "x" is better than "y"...

For example, here's a test text file compression test using "Maximum" values for WinRar, WinZip, and 7-zip ...

i know it is not an excellent test but it is just a quick example. It is just like the test they show as an example on the &-Zip website when compressing the GiMP. They obviously only used it because 7-Zip compressed it better than WinRAR. They wouldnt use something where RAR got better compression would they?!

Doesn't this just tell you to go out and get WinRAR?

Come on, only a 10% compression penalty from 7-Zip yet it's widely supported, easy to use and quick.

Why waste your time with anything else?

seriously i believe popularity is as important as compression ratio.

if u are compressing for ur own usage than ofcourse compression comes first.

my experience:

WinAce

WinRar

WinZip

(I am naming the applications)

I had liked to try out 7Zip but dont think many people in my circle use it.

I would go for WinZip. Even though it is much limited to the file formats compared to WinRar, it has much faster compression. You can extract and compress much faster and effiecient than other programs. I have a friend that works at Symantec and he says that they also use WinZip. WinRar is most likely to be built for home users while WinZip is more of a professional line of compression.

home users/professional users

now this is weird. i dont think winrar is not secure or good enough to be used by organisation.

Zip just happen to be the most widely used format. That's it. That does not make WinZip the software of choice when it cant handle the alternative technologies.

WinAce and WinRar on the other hand accepts other formats too. :)

How is it more effiecent? I suppose it depends on how you define efficiency with compression, but with WinRAR and 7zip clearly able to pack a lot more into a smaller file than Winzip, I fail to see how you may be interpreting Winzip's superior efficiency over the competition.

With WinRAR able to function within a console for scripting purposes, being able to support archives up to 8 terabytes (with Winzip maxed at 4GB), and lastly, having 128-bit encryption (where Winzip's encryption is very weak), WinRAR is far more suited to a professional enviroment than Winzip is.

My 2 cents.

    • Fresh leak suggests OnePlus Pad Lite in the works, key specs revealed by Sagar Naresh Bhavsar OnePlus recently unveiled the mid-range OnePlus 13s and the OnePlus Pad 3 Android tablet in India (the tablet is also coming to the U.S.). Now, it appears that the company is working on another tablet, this time, a budget model called the OnePlus Pad Lite. Supposedly, it will be the successor to the OnePlus Pad Go, which launched in the U.K., India, and European countries. According to the leaked images, OnePlus Pad Lite follows the same design elements as earlier OnePlus tablets. The tablet is shown to have a circular camera at the center of the rear panel, with the logo sitting in the middle. The USB-C port and speaker grills are located on the right side frame of the tablet. The alleged OnePlus Pad Lite measures 254.9 x 166.5 x 7.4mm and weighs 539 grams, which is slightly taller, wider, and thinner, but weighs less compared to the OnePlus Pad Go. The tablet, courtesy of 91Mobiles and OnLeaks, is displayed in blue, which could be the only color option. One image shows the tablet with a cover that doubles as a kickstand, but may be sold separately. Gallery: OnePlus Pad Lite Based on the leaked specs, the OnePlus Pad Lite could feature an 11-inch LCD 1920x1080 resolution 90Hz display. It could be powered by the MediaTek Helio G100 processor and paired with the Mali G57 GPU. The tablet may come with 6GB of RAM and 128GB of onboard storage, with more storage and RAM options available at launch. Reportedly, the OnePlus Pad Lite could feature a 5MP primary camera and a 5MP selfie camera. Under the hood, it could be juiced by a 9,340 mAh battery. On the software side, OnePlus Pad Lite may come with OxygenOS 15.0.1 based on Android 15 out of the box. There is no clarity on which market OnePlus plans to launch the OnePlus Pad Lite in. However, the report suggests that it could be priced under ₹20,000 (roughly $231). Images by 91mobiles x OnLeaks

    • TBF, it has had PST support for quite a while now. But I still want them to add the ability to drag & drop between accounts / PSTs.
    • LibreOffice closes in on Microsoft Office, leaves Windows 7/8 behind in 25.8 Beta 1 by David Uzondu The Document Foundation has released LibreOffice 25.8 Beta 1 for public testing on Linux, macOS, and Windows. This is the second pre-release for the 25.8 cycle and the foundation says that the final, stable version of LibreOffice 25.8 is expected to land at the end of August 2025. Starting off with Writer, LibreOffice's Word, the developers have finally addressed some long-standing annoyances, including a new command to easily insert a paragraph break right before a table. This beta also introduces a useful privacy feature in its Auto-Redact tool, letting you strip all images from a document with a single option. To use it, go to Tools and select the Auto-Redact option: The application has improved its ability to handle different languages for punctuation, preventing mix-ups in multilingual documents. Other notable improvements have also been made. A new hyphenation rule lets you choose to prevent a word from splitting at the end of a page, moving the whole line to the next page instead. Microsoft Word has had this feature for years now. The Navigator now displays a handy tooltip with word and character counts for headings and their sub-outlines. Scrolling behavior when selecting text has been improved, making it less erratic. A new command with a keyboard shortcut was added for converting fields into plain text. Calc gets a lot of new functions that bring it closer to its competitors like Excel, including TEXTSPLIT, VSTACK, and WRAPROWS. Impress now properly supports embedded fonts in PPTX files, which should reduce headaches when sharing presentations with PowerPoint users. Alongside these additions, the project is also cleaning house; support for Windows 7, 8, and 8.1 has been completely dropped. There are also smaller UI tweaks across the suite, like allowing a single click to enter rotation mode for objects in Writer and Calc. macOS users get better integration, with proper support for native full screen mode and new window management features from the Sequoia update. In terms of performance, the team has optimized everything from loading huge DOC files and XLSX spreadsheets with tons of conditional formatting to simply switching between sheets in Calc. These improvements should be noticeable, especially when working with complex documents. A new application-wide "Viewer mode" has also been implemented, which opens all files in a read-only state for quick, safe viewing. On a related note, The Document Foundation has joined efforts by the likes of KDE to encourage Windows 10 users to switch to Linux. Also, you might have heard that Denmark, in a bid to lessen its reliance on Microsoft, has decided to make a full switch to LibreOffice, with plans to begin phasing out Office 365 in certain ministries as early as next month. If you're interested in this release, you can read the full release notes and download the binaries for your platform: Windows, macOS (Intel | Apple Silicon), or Linux (DEB | RPM). You can also get the latest stable version from our software stories page.
