Its editing tools include resizing, rotation, cropping, color adjustments, sharpening, blur, Clone Stamp, and Healing Brush.

Users can compare up to four images side by side, make contact sheets, and batch-convert or rename image collections. The slideshow supports more than 150 transition effects and music. The program can acquire images from scanners and batch-scan to PDF, TIFF, JPEG, and PNG. It can also launch external editors from within the viewer, and a portable version can run from removable storage. FastStone lists personal and educational use as free. The commercial license is listed at $34.95, paid once for a lifetime license with free upgrades, while another plan listing gives $34.95 a month; check the terms before purchase.
