No. Everything runs in your browser - your file never leaves your device. How this is verifiable
PNG is the right choice when your WebP image has transparency or you need lossless edges - for logos, screenshots or graphics. PNG is supported by every program.
The image is painted onto a local canvas and exported as PNG; transparency is preserved. Nothing is uploaded.
WebP has a lossy and a lossless mode; PNG is always lossless and supports a full alpha channel with 256 levels of transparency. That makes PNG the safe target when your WebP holds soft shadows, a logo or a screenshot with a transparent background. PNG is also opened by every image editor, office suite and operating system without extra software - unlike WebP, which some older tools still refuse.

Limitations: PNG files are larger than JPG, especially for photos. For small photo files, WebP to JPG is a better fit.
Yes, PNG fully supports transparency.
No, everything runs locally in the browser.
No, PNG is lossless and passes every pixel through exactly as it arrives. One limitation: any compression marks already baked into the WebP stay put - PNG preserves them faithfully but cannot remove them. So the result is never worse than the source, but it will not be sharper either.
PNG opens practically everywhere - in every browser, image viewer and office program. That is exactly the advantage over WebP, which some older software does not yet recognise.
