A simple command-line tool to convert common image formats to WebP.
cargo intall towebp
You use this tool like cat; just provide a list of files. Here's how you might
convert a.png and some.jpg into a.webp and some.webp, respectively:
towebp a.png some.jpg
This also means you can convert all the PNGs in a directory like this:
towebp *.png
towebp will print errors to stderr if a file fails to parse or decode as an image,
but will continue on with the rest of the files, like cat.
