Multi Resizer resizes images. That's it.

But it is much more than a simple image resizer. You can resize to multiple targets, folders, formats and destinations. You can, in one click resize thousands of images to create a thumbnail image, a smaller low resolution preview image and a full size image for your website gallery in one go. 

Multi Resizer also lets you transform all images between different supported formats such as JPEG, PNG, GIF, TIFF, etc, for easy collaboration with your colleagues.

Using a very simple naming scheme you can numerate and add unique identifiers to the filenames for easy cataloging.

And all is done in your own Mac, no data leaves your computer while resizing, which means no privacy intrusion by uploading your images to a 3rd party server.
