+.Sh NAME
+.Nm pngquant
+.Nd PNG converter and lossy image compressor
+.Sh SYNOPSIS
+.Nm
+.Aq options
+.Op ncolors
+.Pa file
+.Op Ar
+.Nm
+.Aq options
+.Op ncolors
+.Fl
+.Cm < Ns Pa file
+.Cm > Ns Pa file
+.Sh DESCRIPTION
+.Nm
+converts 32-bit RGBA PNGs to 8-bit (or smaller) RGBA-palette PNGs, optionally using Floyd-Steinberg dithering.
+The output filename is the same as the input name except that it ends in
+.Ql -fs8.png
+or
+.Ql -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
+.Fl Fl force
+to overwrite.
+.Sh OPTIONS
+.Bl -tag -width -indent
+.It Fl o Ar out.png , Fl Fl output Ar out.png
+Writes converted file to the given path. When this option is used only single input file is allowed.
+.It Fl Fl ext Ar new.png
+File extension (suffix) to use for output files instead of the default
+.Ql -fs8.png
+or
+.Ql -or8.png .
+.It Fl f , Fl Fl force
+Overwrite existing output files.
+.Do
+.Fl Fl ext
+.Ar .png
+.Fl Fl force
+.Dc
+can be used to convert files in place (which is unsafe).
+.It Fl Fl nofs , Fl Fl ordered
+Disable Floyd-Steinberg dithering.
+.It Fl Fl floyd Op Ar =N
+Set dithering level using fractional number between
+.Cm 0
+(none) and
+.Cm 1
+(full, the default).
+.It Fl s Ar N , Fl Fl speed Ar N
+.Cm 1
+(brute-force) to
+.Cm 11
+(fastest). The default is
+.Cm 3 .
+Speed
+.Cm 10
+has 5% lower quality, but is about 8 times faster than the default. Speed 11 disables dithering and lowers compression level.
+.It Fl Q Ar min-max , Fl Fl quality Ar min-max
+.Va min
+and
+.Va max
+are numbers in range
+.Cm 0
+(worst) to
+.Cm 100
+(perfect), similar to JPEG.
+.Nm
+will use the least amount of colors required to meet or exceed the
+.Va max
+quality. If conversion results in quality below the
+.Va min
+quality the image won't be saved (or if outputting to stdin, 24-bit original will be output) and pngquant will exit with status code
+.Er 99 .
+.It Fl Fl skip-if-larger
+If conversion results in a file larger than the original, the image won't be saved and pngquant will exit with status code
+.Er 98 .
+Additionally, file size gain must be greater than the amount of quality lost. If quality drops by 50%, it will expect 50% file size reduction to consider it worthwhile.
+.It Fl Fl posterize Ar bits
+Truncate number of least significant bits of color (per channel). Use this when image will be output on low-depth displays (e.g. 16-bit RGB).
+.Nm
+will make almost-opaque pixels fully opaque and will reduce amount of semi-transparent colors. When this option is enabled the default filename suffix is
+.Ql -ie-fs8.png
+/
+.Ql -ie-or8.png .
+.It Fl Fl strip
+Remove optional chunks (metadata) from PNG files.
+.It Fl Fl transbug
+Workaround for readers that expect fully transparent color to be the last entry in the palette.
+.It Fl v , Fl Fl verbose
+Enable verbose messages showing progress and information about input/output. Opposite is
+.Fl Fl quiet .
+Errors are output to
+.Pa stderr
+regardless of this option.
+.It Fl V , Fl Fl version
+Display version on
+.Pa stdout
+and exit.
+.It Fl h , Fl Fl help
+Display help and exit.
