cwebp does not support URL in input file?

[pinal.op...@gmail.com]

I am trying to convert jpg into webp. I am setting https URL as an input file.

I am using this command to convert webp

   cwebp -q 75 https://imgur.com/a/ggwiHOi -resize 525 300 -o C:\images\webp\5aabaa66e6dab_json_image_1521199718.webp

then I get the following error 

SHCreateStreamOnFileA(filename, STGM_READ, stream) failed 8007007b

Error opening input file https://imgur.com/a/ggwiHOi (8007007b)

OpenInputStream(filename, &stream) failed 8007007b

cannot open input file 'https://imgur.com/a/ggwiHOi'

Error! Could not process file https://imgur.com/a/ggwiHOi

Error! Cannot read input picture file 'https://imgur.com/a/ggwiHOi'

Hi,

HTTP and other network resources aren't supported for input by cwebp, it works on files present on the file system. For this you can download the image via your web browser or using curl/wget from the command line.
