If your WebP has a transparent background — a logo, an icon, a cut-out product shot — PNG is the conversion you want. It is the only one of the two classic formats that can carry an alpha channel, so nothing about the image changes except the container.
The output is lossless, so the PNG is pixel-identical to the decoded WebP. Whatever quality the WebP already had is preserved exactly; it just becomes a larger file, because that is the price of losslessness.
できること
Transparency survives
The alpha channel is carried across untouched. No white box appears behind your logo.
Lossless output
PNG encoding does not discard information, so the conversion adds no new artefacts.
Broad tool support
PNG is accepted by design tools, office software and print workflows that reject WebP.
Runs on your device
Decoding and encoding both happen in the browser tab.

The browser decodes it including any transparency.

Convert to PNG
Pixels and alpha are written into a PNG container. There is no quality setting because none is needed.

You get a lossless PNG with the transparency intact.
