OSX Batch Image Resizer is a simple to use, free application for OSX developed by Iron Star Media Ltd to allow users to resize hundreds or thousands of images quickly and easily.

Batch Image Resizer performs one simple task in a fast and easy to use way – resizing a large number of images quickly on your computer. The software allows you to resize a collection of images (from 10’s to 1000’s) so that they are all resized to a specific width or height while maintaining their original aspect ratio. You can also resize your images so that they all fit within a specific sized box (useful for resizing images for eBay for instance).

Saving your files as JPEGs allows you to resize your photo collection for archiving or emailing to family. Saving your files as 24-Bit PNGs maintains full alpha channel support so that you can resize icon-sets or buttons for your website without losing transparent or semi-transparent backgrounds.
