MinifyMe

MinifyMe is a simple-to-use application created in Adobe Air, which can reduce the size of your JavaScript and CSS files to create a single, compact file.
It comes in handy if you want to optimize your website that contains numerous CSS and JavaScript files, without having to customize any settings. The task is performed automatically.

Adobe Air-based app with a simplistic graphical interface

Make sure to download and install Adobe Air unless you already have it, since the app cannot run without this platform. Once installed, MinifyMe gets launched in a small window that has an empty box designated for dragging and dropping CSS and JS files from Windows Explorer or any other file manager you use.

Merge multiple JavaScript and CSS files into a single one

If you want to compress multiple files at the same time, hold down Ctrl or Shift while clicking to make a multi-selection, or trigger the Ctrl+A combination to select everything from a folder. However, if unsupported files are in the selection, then it will not be possible to drop the items.
When processing many files at the same time, you should know that they will be combined into a single, compressed file instead of creating separate containers. The file is automatically named pack.css by MinifyMe and placed in the same location as the source.
If you attempt to compress a new file in the same directory, the existing pack.css file gets automatically overwritten, without requesting your confirmation. This means that you have to be careful not to accidentally overwrite previously compressed files.

Simple and speedy app for compressing JavaScript and CSS files

We have noticed that MinifyMe manages to create significantly smaller files in a very short amount of time. However, the program doesn't make any room for customization and it's unclear about the approach it takes to compress the files.
