FastStone Image Viewer is a complete imaging solution for you that can help you in viewing your photos, editing and publishing them. This program offers all the tools that you may need to process your raw images, like photo resizer, format converter, contrast and color changer and much more.
Its "Image explorer", with a thumbnail preview, can help you to locate images easily and quickly. You can zoom in/out any image in the preview window without opening it. But it is somewhat wrong if FastStone Image Viewer is called just a viewer, because it offers a wide variety of editing tools that are not found even in some good image editors. FastStone Image Viewer enables you to change contrast, brightness, sharpness and color settings (RGB) of images easily. You can use the "Red Eye Effect Removal" tool for your digicam photos, or apply special effects like Grayscale, Sepia and Negative. FastStone Image Viewer also has a framing tool that can frame your photos in a single click, and a draw board that allows you to add colorful comments to your photos.
Additionally, you can create slideshows, multipage files, panoramas, contact sheets and much more. One of the best features of this tool is its “EXE slide show creator” that can create interactive slide shows in a couple of clicks - that can be run on any computer without installing any kind of third-party software. You can compare two images using the built-in image comparer, or use the batch renamer to rename thousands of images in two clicks.
FastStone Image Viewer gives you all that for free, and its uses are truly endless.
