A light tool to convert images to pixel arts using the 16-colors palette available on pxls.space.

Java 1.7+ is required to run the program.

A compiled version can be downloaded in the releases section.

Usage: java -jar PxlArtGenerator.jar <source image> <output image> [options]
  Options:
    --help
      Displays this menu
    -height, -h
      The output image height
    -output-size
      The size of the pixels on the output image
      Default: 1
    -palette, -p
      The palette to be used to draw the output image; it must be in 
      hexadecimal 
      Default: 0123456789abcdef
    -width, -w
      The output image width

Default options; the output size will be the same as the input, using all the available colors:

java -jar PxlArtGenerator.jar source.png output.png

The output pixels will be 10 times larger (useful to avoid anti-aliasing when sharing the image):

java -jar PxlArtGenerator.jar source.png output.png -output-size 10

The palette will only use white, light gray, gray and black:

java -jar PxlArtGenerator.jar source.png output.png -palette 0123

The output image will be 20 pixels long (horizontally), and the height will be calculated according to the original aspect ratio:

java -jar PxlArtGenerator.jar source.png output.png -width 20

The output image will be 50 x 50 pixels (warning, the aspect ratio can change!):

java -jar PxlArtGenerator.jar source.png output.png -width 50 -height 50
