Unsupported Color conversion

Yes, I do also get that message for that image with cwebp.

Vips also fails, with this message: icc_import: no input profile

Imagick, Gmagick and ImageMagick succeeds.

I have uploaded the generated webp here:

Unfortunately I do not have time to investigate this further before my vaccation

@roselldk Thanks alot Rosel! Enjoy your vacation ??

@roselldk I’ve found the source of issue here: https://bugs.chromium.org/p/webp/issues/detail?id=311#c5

And here is a workaround for imagemagick: https://groups.google.com/a/webmproject.org/forum/#!topic/webp-discuss/MH8q_d6M1vM

cwebp uses linux library libjpeg for jpeg convertion and it has a bug for images with CMYK color profiles. Developers of imagemagick created workaround for conversion from CMYK to RGB. So for suck images we can add additional step (convert to RGB colorspace first) if imagemagick or php imagick installed on system.
