Want to resize your images without any extra software installed on your Mac? Then this post is for you, we are using existing application named Automator to do the work for us.

WHAT IS AUTOMATOR

Automator is an application developed by Apple for Mac OS X that implements point-and-click (or drag-and-drop) creation of workflows for automating repetitive tasks into batches for quicker alteration, thus saving time and effort over human intervention to manually change each file separately. Automator enables the repetition of tasks across a wide variety of programs, including the Finder, the Safari web browser, iCal, Address Book and others. It can also work with third-party applications such as Microsoft Office, Adobe Photoshop or Pixelmator. Automator was first released with Mac OS X Tiger

HOW TO DO

    Automator is certainly a good solution for some occasional resizing. There are also other nice free options, such as ImageMagic (command-line utility), Preview, etc.

    However, if this is a part of your job and you need a true flexibility, a special-purpose application will save you a lot of time, and offer much more opportunities. Many users chose our batch image resizer Resize Sense (http://veprit.com/resizesense) for its outstanding flexibility and convenience.

    Disclaimer: I am the developer. You better judge Resize Sense yourself. The introductory video on the product website will tell you exactly what is so special in Resize Sense. There is a free demo version.
