Sometimes we need to optimize our images so they can take up less disk space and load faster in our websites. A very nice and easy to use tool for everyone that can help us optimize our image files for the web by removing EXIF, other metadata and unnecessary comments is Trimage.
This image optimizing program is inspired by ImageOptim which is another open source program used to optimize images files in machines that run Mac Os X.

If you come from a Mac OS X background and are familiar with the ImageOptim tool you will see that the tools look like they are the same app. The two following screenshots are taken in Mac OS X and Ubuntu machines. The first one shows ImageOptim tool running in a mac computer and the second one in an Ubuntu Linux machine.

To compress an image file with Trimage image compresser program just click on the Add and compress button like shown in the following picture.
Select the image you want to optimize and double click on it. The program will automatically start the compression and at the end will give you information about the old size of the image, the new size and the compression amount.
