PhotoStamper adds a reversible date stamp to digital pictures with no quality degradation. The stamping process is nearly lossless. The application automatically reads the date of the original picture from a JPEG file and places a stamp, without modifying pixels outside the stamp area. PhotoStamper can process many images at a time and even remove a stamp later to restore original images. Version 2.1 features a multilanguage date/time format, EXIF date support, a fully customizable stamp (with options for position, size, font, and color), instant previewing, a transparent background, and Windows Explorer integration.
