So what is it?

Keka is a free file compression and extraction app for macOS and iOS. It lets you take one or more files and pack them into a compressed archive, which reduces their total size and makes them easier to store or send. You can also unpack archives you receive from others, even if they were created on a different platform or with a different tool. The app supports multiple archive formats, so you are not locked into a single type of compressed file. When compressing, you can add encryption to protect the contents with a password. This is useful when you want to share sensitive files without worrying about who else might be able to open them. Keka is available through its own website at keka.io, and this GitHub repository serves mainly as a support hub. The issues tracker is where users report bugs or request features, the wiki collects how-to knowledge from the community, and the discussions section is for general conversation about the app. The releases section also hosts older versions for anyone who needs a specific past build. The source code is not published here. If you want to download and use Keka, the main website is the right starting point. If you have found a bug, want to request a feature, or want to help with translations so the app works well in more languages, this GitHub page is where to contribute.
