3 Apps for Optimizing Images


Optimizing Images: Optimizing the Pixelmator icon with ImageAlpha.
3 applications for optimizing images. Some time last year, I blogged about TinyPNG. An excellent online tool for optimizing PNG images. However, online services can sometimes be a bit unreliable on a daily basis. Partly, because you need to remember, where you found it. Partly because of the reliability. Can I be absolutely sure, the service is up, when I need it?

Maybe you should just install a desktop app. I just stumbled upon 3 apps for the mac, which optimize and compress both bitmap and vector graphics.

1. ImageAlpha for Optimizing Images in PNG Format

ImageAlpha converts 24-bit PNG to paletted 8-bit with full alpha channel (which basically means transparency). This dramatically reduces the file size with only a minor loss of quality. Such images are compatible with all browsers, and even degrade well in Internet Explorer 6.

2. ImageOptim for Optimizing Images in PNG, JPG, and GIF Format

ImageOptim optimizes images so they take up less disk space and load faster by finding the best compression parameters and by removing unnecessary comments and color profiles. It easily shrinks images that are “Saved for Web” in Photoshop.

3. SVGO for Optimizing Images in the vector SVG format

SVG Optimizer is a NodeJS based tool (you need to install NodeJS first) for optimizing vector graphics in the SVG format. SVG files usually contains a lot of redundant and useless information such as editor metadata, comments, hidden elements, default or non-optimal values and other stuff. SVGO removes all unnecessary information and thereby reduces the file size without affecting the SVG rendering result. SVGO is a command line tool, but you can put a graphic user interface on top of it.
