ABRViewer is an open source utility that allows one to preview Photoshop brushes without having to load them first in Adobe Photoshop. It hardly needs to be said how useful this tool can be. Designers who frequently work with Photoshop regularly download different sets of brushes that needs to be tested before they can be used. Loading and unloading these brushes in Photoshop is cumbersome. Also the default preview size for these brushes in Photoshop is too small to make out anything. So they often need to be used on a blank canvas to test. All this is extremely time consuming.
ABRViewer comes as breather. Simply load the brushes into the tool and click on it to generate a preview. ABRViewer allows you to preview several brushes at the same time making it possible to make comparisons. You can load and view as many brushes as your screen size allows. You can even save your brushes under a favorite section.
ABRViewer also lets you export brushes as PNG images in full resolution. You can save these images for reference or for later use, or publication on the Internet. The brush background and foreground color are customizable. I recommend this tool to all Photoshop users.
