\fBpngquant\fP 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 \fI-fs8.png\fP or \fI-or8.png\fP (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 \fI-force\fP to overwrite.
