Convert PNG to WEBP
Free, in your browser, with no watermark and no signup. Both are image files; this changes how the picture is stored.
Why you have a PNG file
If the PNG is going on a website, WEBP is simply the better format: meaningfully smaller at the same quality, and supported by every current browser. Page weight is a ranking factor, and images are usually most of it.
What the conversion actually does
The image is re-encoded as WEBP, which keeps transparency, unlike JPG, while being substantially smaller than the PNG.
Worth knowing first
WEBP is for the web specifically. Some desktop software and older tools still will not open it, so keep the PNG if the file also has to be handed to a person.
