       gif2webp - Convert a GIF image to WebP

       gif2webp [options] input_file.gif -o output_file.webp

       This manual page documents the gif2webp command.

       gif2webp converts a GIF image to a WebP image.

       The basic options are:

       -o string
	      Specify the name of the output WebP file. If omitted, gif2webp will perform conver-
	      sion but only report statistics.

       -h, -help
	      Usage information.

	      Print the version number (as major.minor.revision) and exit.

       -lossy Encode the image using lossy compression.

       -q float
	      Specify the compression factor for RGB channels between 0 and 100. The  default  is
	      In  case	of lossless compression (default), a small factor enables faster compres-
	      sion speed, but produces a larger file. Maximum compression is achieved by using	a
	      value of 100.
	      In  case of lossy compression (specified by the -lossy option), a small factor pro-
	      duces a smaller file with lower quality. Best quality is achieved by using a  value
	      of 100.

       -m int Specify  the  compression  method  to  use.  This  parameter controls the trade off
	      between encoding speed and the compressed file size and quality.	 Possible  values
	      range  from  0  to 6. Default value is 4.  When higher values are used, the encoder
	      will spend more time inspecting additional encoding possibilities and decide on the
	      quality  gain.   Lower value can result is faster processing time at the expense of
	      larger file size and lower compression quality.

       -f int For lossy encoding only (specified by the -lossy option). Specify the  strength  of
	      the  deblocking  filter,	between  0 (no filtering) and 100 (maximum filtering).	A
	      value of 0 will turn off any filtering. Higher value will increase the strength  of
	      the  filtering process applied after decoding the picture. The higher the value the
	      smoother the picture will appear. Typical values are usually in the range of 20  to

       -v     Print extra information.

       -quiet Do not print anything.
