Create a compressed file

1. With Keka compressing files is just drag and drop your desired files and folders to Keka in the Dock. You can drop as many as you want at once, and all of them will be archived in one compressed file.

2. When you drop some file to compress, Keka progress window will appear showing you the progress and letting you to pause or cancel the process.

3. Once the file is created, Keka using Growl will advice you that your file was created, or if there was an error.

Your compressed file will appear at the same location as the file you dropped to Keka at first point.

Extract a compressed file

1. Extracting a file with Keka is as easy as making double click in the compressed file or drag and drop it to Keka in the Dock. As in compression, Keka progress window will appear to show you the extraction status and letting you to pause or cancel the action.

2. If the archive is password protected, Keka will advice you and let to put the password to continue the extraction.

Main window

1. In Keka main window you can choose your desired format to compress: 7z, Zip, Tar, Gzip or Bzip2.

2. Also you can choose the compression method, that goes from store, without compression at all, to ultra, the best but lowest compression. You choose!

3. If you're compressing a big file, you can split it in parts just selecting the size you want, in Bytes (B), Megas (MB) or Gigas (GB).

4. With 7z and Zip you will have the opportunity to create password encrypted files to better protect your privacy. It's as easy as write your password in the box, and drag and drop files to Keka in the dock.

5. Just with 7z, you can encrypt the filenames, so without password no one will know what type of files are inside the encrypted file.

6. With 7z, yo also can create a solid state file.

7. With "Exclude Mac resource forks" you can create archives that looks clean in non Mac systems, as Linux or Windows.

8. If you want to delete the files you're compressing after the operation, you can check the option to do it automatically.

9. If you want to store data, use Tar format. It doesn't compress at all, but is useful to archive files for a later compression.

10. You have to know that Gzip and Bzip2 just compress on file at once. If you need to compress a folder or a couple of files with that format, archive it before in Tar, select "always compress" in the Keka dock menu, and compress that Tar file with Gzip or Bzip2.

Dock menu

1. Keka has a nice and useful Dock menu, where you can choose your desired format, method, and if you want to compress or extract all the files you drop or just let Keka think for you an automatic action depending on files you dropped.


1. In Keka preferences window you can choose your desired format and method that Keka will use by default.

2. You can choose your desired action (as in the dock menu). It can be an automatic action, to let decide Keka to compress or extract depending on files you dropped, or maybe you want to compress or extract everything you drop to Keka.

3. You can choose a default destination, that can be a concrete folder, next to archive or maybe you want Keka to ask you each time where to create the file. Also you can set the name of new archives, that can be the same as the files you drop ("compressed file" for multiple files) or your desired name.

4. If you're going to compress a lot of files in different formats or method, just uncheck the "Close Keka when no window visible" to keep Keka opened and use the Dock menu anytime.

Uninstall Keka

1. Keka is as light as easy to uninstall. Just delete the

2. Also you can delete the preferences files, stored in your user folder 'Library/Application Support/keka'.
