Gwenview 17.04.0 with KDE Frameworks 5.33.0 and Qt 5.8.0 also can not open webp with Gwenview.

There is/was a library "/usr/lib/kde4/plugins/imageformats/kimg_webp.so" but there is no library for webp in "/usr/lib/qt/plugins/imageformats/".

Even the KImageFormats plugin for QImage does not include this format.

So it seems to me that there is just no support for webp in Qt 5.

You need to install qtimageformats

Thanks a lot. I totally missed that qtimageformats and kimageformats are not the same packages and thought it could be related to this bug report.

Sounds like this should be reported to your distro, asking them to mark qtimageformats as a required dependency of Gwenview.
