PNG to WebP Converter

Turn a PNG into a WebP right in the browser, in a single step.

Typical use: your target platform takes WebP but not PNG. Because WebP supports both lossy and lossless modes plus an alpha channel, a PNG's transparency carries straight through, and the re-encoded file usually lands noticeably smaller than the source PNG for the same picture - the exact reduction depends on the image.

The file picker sits above a small set of option fields that control how each PNG is re-encoded as WebP; the defaults suit typical web-delivery use, so a straightforward conversion needs no adjustment. The re-encode runs on an HTML5 canvas, which lets you nudge the output quality to balance a leaner WebP against how faithfully it tracks the original PNG before you save it.

Every step - reading the PNG, redrawing it, and writing the WebP - happens inside this tab through the Canvas API, so the PNG stays on your device and is never uploaded. What you convert is dropped when the page session ends and is never handed to an analytics or tracking service, and no account or signup is involved.
