I have to resize images all the time for use on the web. Ecto, the blogging application that I use most of the time, has a built-in feature to do this. However, for other times, it’s much easier to just resize the image and use it at 100% it’s size, and not have to worry with settings inside the application to do this work for you (or if you’re coding it in by hand).

I have an Applescript up on the Downloads page, if anyone is interested, that will automatically convert an image to a 64X64 image, assuming that you started with a square image to start with. I use this a lot for shrinking Mac icons into managable PNG images for use on the site.

For the meat of this tip however, I just discovered an easy way to convert an image’s size, with a free app that comes bundled with OS X (unfortunately not Preview). That application is the Color Sync Utility. Just use Spotlight to find that, open up your image in the app, click the button that resembles a “Zoom to Fit” button in Preview, but this is a resizer button in Color Sync Utility.

Click that button, and you can resize by percentage, width, height, etc. This is a great little workaround and gives me more flexibility than my Applescript or having to use Photoshop to accomplish the same thing. If anyone else has an easier way, I’d be glad to hear it!
