FastStone Image Viewer 7.8 Image viewing app for Windows

A fast, stable, user-friendly image browser, converter and editor.

FastStone Image Viewer is an excellent replacement for your built-in Windows viewer which is not only more intuitive, but also provides many editing features which come in handy when you're looking to touch-up your images.

To start, FastStone Image Viewer provides a clean interface which facilitates a slideshow. From the full screen view, you can also perform a wide array of image editing such as auto color correction, modification of lighting levels and more. All of these editing effects are available from the right-click menu or if you're in the main interface, from the menu bar.

When it comes to editing with this application, you are given the options of undo/redo which means you're given the full flexibility of experimenting. When done, you can either overwrite the original image or save it as a new image anywhere you choose.

Editing functions and color correction here are superb, but you can also use FastStone Image Viewer to re-size or convert the format of your images. You may also rotate, clip or perform cropping on your pics.

This program supports a wide range of different image formats including JPEG, BMP, GIF, PNG and other popular formats. It's a little hit and miss when it comes to support for RAW formats from digital SLRs and mirrorless cameras but it can read CRW, CR2, NEF, PEF, RAF, MRW, ORF, SRF, ARW, SR2, RW2 and DNG files.
