Keka is an open source Mac utility that enables you to create and extract archive files with ease. Unlike Mac's default archive file manager, this application supports a wider variety of formats, provides you with extra file compression settings, and much more.
Archive Utility, Mac's default archive file manager, is an app that you don't need to launch in order to create or extract compressed files. You simply double-click archive files to extract them and use Finder's contextual menu to extract them. The app can be found with a simple Spotlight search. Once you launch it, you'll notice that it features a very small amount of useful features. For instance, it supports only one output format when creating archive files (ZIP), doesn't let you extract multiple compressed files at the same time, etc. For this reason, apps like Keka were created.
This program allows you to extract files with the following extensions ZIP, ISO, CAB, ACE, and many others. Furthermore, it lets you create archives of various formats, not just ZIP (drag the files you wish to compress over its interface or Dock icon).
Another important aspect is that it comes with a split option which comes in handy when creating archives from large files. Furthermore, it takes a very small amount of time to offer you the results you need, supports batch processing, and uses minimum CPU resources while running on your Mac.
With that being said, Keka proves to be a reliable solution for handling archive files on your Mac.
