--------------------------------------------------------------------------------
Automatically compress JPEG/JFIF, PNG*, BMP, GIF and TIFF** images into WebP or
AVIF using cwebp, gif2webp, avifenc, cavif, tiff2png and  bmp2png.

*  Caution: APNG animation will not be preserved!
** Caution: Alpha-channel will not be preserved!

Only the smallest resulting file is kept. If the original (unconverted) file was
kept as smallest, it will not be converted next run (skipped).

Almost in-place conversion. Requires at most 4x as much space as the largest
image (by file size, not image dimensions) in the set

Conversion time depends mostly on your hardware and can easily reach multiple
hours when converting large (thousands of pictures) datasets. JPG is faster to
convert, PNG is slower  and BMP and TIFF are slowest.

Does not accept arguments to pass-through to codecs! Edit source code to see
defaults and tweak codec parameters. See cwebp, gif2webp, avifenc, cavif and
tiff2png manpages to understand parameters.

Dependencies (cwebp.exe, gif2webp.exe, avifenc.exe, cavif.exe, bmpp2png.exe,
tiff2png.exe) are expected to be found in ./lib subfolder or on PATH

                                          convert GIF and TIFF images
