Problem - no webP format - in latest version 25.4.0

[Sylverayda]

What a surprise: much fewer files types to choose from. No webP too...

You either need to use Save a Copy or enable Legacy Save As in your file handling preferences... Or ensure that the current file state meets the requirements of WebP (colour mode, bit depth, layers, alpha channels).
