PixBuilder Studio comes in a very small size, just 3MB download, a good indication that it will be light on resources, the official requirement is only 512RAM, during installation you can choose to install it as portable on a USB thumbdrive.
Its interface is tightly integrated (no floating panels) the layout resembles PhotoShop, most tools are located in the very same place, this photo editor has all of the features that a home user will need: photo resizing, cropping, import from scanner, brightness adjustment, contrast, auto levels, RGB, hue/saturation, curves and colorize. I own PhotoShop as well and there isn’t a single tool that I normally use there and can not be found on PixBuilder Studio, there are more features in PhotoShop of course but most home users will never need them.

PixBuilder Studio free photo editor
The default special effects are limited to dithering, blur (quick, motion, Gaussian), sharpness, emboss and few others, all very basic. There is support for Adobe Photoshop 8BF filters in the form of plugins, you will need to add those after installation. I enjoyed the clone stamp, and magnetic lasso tool, these are not found often in free graphics editors., the program is multilingual and you can translate it into your own language if it is not available yet, the developer will include it in the next release.
