Th-MakerX makes resized image files of dropped image files. You can drop folders which contain image files, too. Th-MakerX resizes image with pre-specified resize mode.

You can use Th-MakerX as a simple image resize tool or a simple JPEG/PNG converter.


Drag Th-MakerX to any location of your hard disk such as /Applications, ~/Applications.


You cannot open Th-MakerX with normal procedure for the first time because it has no developer ID. Please open with fallowing steps:

  1. Click the application icon with pressing "Control" key or right-click it on the Finder.
  2. Choose "Open" from displayed contextual menu.
  3. Click "Open" button on the confirmation dialog. Enter the name and the password of administrator if required.

You should perform the upper procedure once at the first launch time on each user account. You can open the application with normal procedure (double click application icon and so on) after performing these.


Drag Th-MakerX into the trash.
