7-Zip v23.00 Download




Here you can download the latest version of 7-Zip. 7-Zip is a file archiver with a high compression ratio. You can use 7-Zip on any computer, including a computer in a commercial organization. You don't need to register or pay for 7-Zip.
7-Zip is a file archiver with a high compression ratio for ZIP and GZIP formats, which is between 2 to 10% better than its peers, depending on the exact data tested. And 7-Zip boosts its very own 7z archive format that also offers a significantly higher compression ratio than its peers—up to 40% higher! This is mainly because 7-Zip uses LZMA and LZMA2 compression, with strong compression settings and dictionary sizes, to slow but vastly improve density. If a zip tool gains its appeal from its ability to efficiently compress files, then 7-Zip proves it has a little bit o’ magic.
7-Zip
After you effortlessly download and launch 7-Zip, you’ll quickly discover its simple and easy to navigate interface. The main toolbar contains 7-Zip’s most used features and there are several menus that allow you to dig deeper within. For example, the Extract button lets you easily browse for or accept the default destination directory for your file, while the View menu contains a Folder History, and the Favorites menu lets you save up to ten folders. 7-Zip also integrates with the Windows Explorer menus, displaying archive files as folders and providing a toolbar with drag-and-drop functions. You can also alternate between a single or dual-pane view.

Editor's Note:
What's new: 7-Zip now can use new ARM64 filter for compression to 7z and xz archives. ARM64 filter can increase compression ratio for data containing executable files compiled for ARM64 (AArch64) architecture. Also 7-Zip now parses executable files (that have exe and dll filename extensions) before compressing, and it selects appropriate filter for each parsed file: BCJ or BCJ2 filter for x86 executable files, ARM64 filter for ARM64 executable files. Previous versions by default used x86 filter BCJ or BCJ2 for all exe/dll files. Default section size for BCJ2 filter was changed from 64 MiB to 240 MiB. It can increase compression ratio for executable files larger than 64 MiB. UDF: support was improved. cpio: support for hard links. Some changes and optimizations in WIM creation code. When new 7-Zip creates multivolume archive, 7-Zip keeps in open state only volumes that still can be changed. Previous versions kept all volumes in open state until the end of the archive creation. 7-Zip for Linux and macOS now can reduce the number of simultaneously open files, when 7-Zip opens, extracts or creates multivolume archive. It allows to avoid the failures for cases with big number of volumes, bacause there is a limitation for number of open files allowed for a single program in Linux and macOS. There are optimizations in code for 7-Zip's context menu in Explorer: the speed of preparing of the menu showing was improved for cases when big number of files were selected by external program for context menu that contains 7-Zip menu commands. There are changes in code for the drag-and-drop operations to and from 7-Zip File Manager. And the drag-and-drop operation with right button of mouse now is supported for some cases.

Thanks for the heads-up! I doubt I'd have noticed a thing like this otherwise.

@BlueRay: Please keep in mind even update servers may infect themselfes. This has been done in the past multiple times. The last time I know was some kind of banking software which downloaded an infected update (crypto trojan) from its compromised update servers. Because autoupdates were ON by default, half its clients were infected.
On the one hand may be wise to let programs autoupdate themselfes if you trust them >>and the whole chain<<.
On the other hand it may be even better to disable autoupdates and do the patching the manual way on critical infrastructure. Remember the time when Windows 10 updates broke some computers? (Isn't it still a thing today?)
My grandma would be better off with autoupdates which >>I<< enable, for the most important programs.
Personally I feel safer with a weekly "patchday", where I download (or check for) program updates. A big PRO is you do not have to have dozens of programs running in the background, checking for updates every few minutes / hours. Saves bandwidth, ressources and therefore energy (a small bit). "Green IT by disabling autoupdaters." ;-)
I used 7-zip for many many years and still use it today. It offers all the formats you want your archive program to support. RAR, ZIP, 7Z, WIM, ISO and a lot more is supported. That is what I care of the most, after the fact it's free without any hidden fees and does not come with any spyware, adware, other crap bundled. ("Hi FlashPlayer!").
I do not care about the security issue found here. Honestly: Every program has these. But after escalating the issue to the publisher you see if you may trust them in the future. If a bug does not get patched, this is far worse from my point of view than a program who has thousands of bugs but they get fixed in week 1. The publishers of 7-zip did their job right and fixed the bug. They communicated this to the public the right way (AFTER the patch is available but still in a reasonable "short" period of time), so no bad feelings about this.

IT department uses 7zip, no update queued as of right now.
IT department releases win10 on newer (Dell) laptops, and I'm not sure they know what to deactivate and what not.
As you might think, my trust in my company's IT department is not that big

@386SX I understand that but a notification prompting user to go to the website and download the new version is the bare minimum for security. It is the most popular zip tool yet it expects users to read tech blogs to find out their version is not secure. This is bad.

Yet it doesn't have an auto update or an update notifier. And this is why it's bad and dangerous when applications can't auto update.
