Though it’s lightweight and completely free, FastStone Image Viewer has the power and features to be the primary image editor for most users and the go-to “daily driver” for pros. It packs an impressive array of tools, brushes, filters, effects, and extras in a classic (and customizable) layout. It can resize, rotate, and crop images; fix red-eye and other image flaws; add borders, watermarks, and special effects; convert batches; and do far more, and better, than it should be able to for free.
From FastStone Soft: FastStone Image Viewer is a fast, stable, user-friendly image browser, converter and editor. It has a nice array of features that include image viewing, management, comparison, red-eye removal, e-mailing, resizing, cropping and color adjustments. Its innovative but intuitive full-screen mode provides quick access to EXIF information, thumbnail browser and major functionalities via hidden toolbars that pop up when your mouse touch the four edges of the screen. Other features include a high quality magnifier and a musical slideshow with 150+ transitional effects, as well as lossless JPEG transitions, drop shadow effects, image annotation, scanner support, histogram… It supports all major graphic formats including BMP, JPEG, JPEG 2000, GIF, PNG, PCX, TIFF, WMF, ICO and TGA.
