How to Quickly Create Thumbnails or Resize Images in OS X

Using ThumbsUp you can easily drag-and-drop batches of images to create thumbnails. It supports any and all image formats supported by Mac OS X and QuickTime (including PDF documents).

  1. First things first, download and install the small (and free) ThumbsUp application from Devon-Technologies. Just open the zip, then the .dmg, then drag ThumbsUp to your Applications folder. Launch it from there.

  3. The Preferences window will appear. From here you can define how you want your images to be created – everything from size, quality, file type to name.

  5. After you’ve set the preferences to your liking, close the window. Drag one or more images – or folders of images – onto the ThumbsUp icon in your OS X dock.

  7. And thumbnails will be created for each and every one of the images. The output format, name etc will all depend on how you opted to set up ThumbsUp.

    I’ve got a couple of shell scripts I’ve written to do similar work, but it’s a pain to remember the parameters each time I use it. Photoshop has a similar batch processing script, but this is certainly a nicer looking tool than both of those – thanks!
