xJigsaw combines xjig with a simple GUI which allows easy creation of jigsaw puzzles. There is no need to install xJigsaw, and it does not need xjig. Everything is in a single file. Just download it, unzip it, and run it. It works with png, gif, jpg, tif, and bmp images, and offers image previews. The user can fix the rotation angle of puzzle pieces when dragging and can choose different shapes for the puzzle pieces. Puzzle pieces snap to 90 degree angles. The user can swap mouse buttons, set the width of the puzzle, and set the number of puzzle pieces.
