NAME
pngquant - PNG image optimising utilitySYNOPSIS
pngquant [ options ] <ncolors> [pngfile [pngfile ...]]pngquant [ options ] -map mapfile [pngfile [pngfile ...]]
Note that it's required to specify the number of colors (<ncolors>) or the mapfile. Arguments in square brackets are optional.
DESCRIPTION
This manual page documents briefly the pngquant command.pngquant quantizes one or more 32-bit RGBA PNGs to 8-bit (or smaller) RGBA-palette PNGs using either ordered dithering or Floyd-Steinberg diffusion dithering (default). The output filename is the same as the input name except that it ends in -fs8.png or -or8.png (unless the input is stdin, in which case the quantized image will go to stdout). The default behavior if the output file exists is to skip the conversion; use -force to overwrite.
OPTIONS
- -force
- Overwrite existing output files.
- -ordened, -nofloyd, -nofs
- Use ordered dithering.
- -verbose, -noquiet
- Print status messages.
- NOTE:
- the -map option is NOT YET SUPPORTED.
EXAMPLE
Creating a new image with the number of colors reduced to 64:- pngquant 64 image.png
- The resulting image will have 64 colors and will be saved as image-fs8.png.
