Get a WebP out of the browser-only world and into a TIFF that desktop and print software will open.

WebP is excellent on a web page and awkward everywhere else — plenty of print software, document systems and older desktop applications still will not open one, which is usually what sends people looking for this conversion. TIFF is the safest destination, being both lossless and universally supported by that category of software. The alpha channel survives: when the WebP carries transparency, the TIFF is written as RGBA with the ExtraSamples tag set so other applications read the alpha correctly, and opaque images are written as RGB. One caveat worth stating plainly — if the WebP was saved lossily, as most web images are, the TIFF inherits whatever detail was already lost. It preserves the image perfectly from here on rather than restoring anything. Note that only the first frame of an animated WebP is converted, since baseline TIFF output here is a single image.
WebP was designed for the web, and many print, design and document applications never added support. TIFF is the format that category of software reliably opens.
Yes. Transparent WebPs are written as RGBA with the ExtraSamples tag set so other applications interpret the alpha channel correctly.
No. If the WebP was lossy, that detail is gone. The TIFF prevents any further loss from this point on.
Only the first frame is converted, since the TIFF written here is a single image.
