About PNG to WebP Converter — Free Online Tool

PNG to WebP re-encodes a PNG as WebP, which normally stores the same picture in far fewer bytes while keeping its transparency.

Because WebP supports an alpha channel there is nothing to flatten and no background colour involved — transparent pixels come through transparent, which is the whole reason to pick WebP over JPG for a logo or an icon. The encode is lossy at a default quality of 92, so this is not a reversible round trip out of a lossless PNG; it is a deliberate trade of exact pixel values for size. Flat graphics usually shrink dramatically, photographs rather less.

The PNG is decoded and the WebP written in your own tab, with nothing posted to a server.

Replacing heavy PNG assets on a site without losing transparent edges, cutting the weight of an icon sheet, serving smaller images now that browsers all read WebP, and trimming a repository full of exported graphics.
