Upload a PNG here and download it re-encoded as WebP; transparency is preserved and the file usually comes out smaller.
PNG to WebP Converter
Turn a PNG into a WebP right in the browser, in a single step.
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.
Key features
- Opens your PNG locally in the browser - the file is never uploaded to a server.
- Redraws the image on an HTML5 canvas and re-encodes it as WebP.
- Lets you nudge the output quality to balance a leaner WebP against how faithfully it tracks the original PNG.
- Exports the result as a downloadable blob, with no server round-trip.
- Builds the download link for the output entirely client-side.
When to use it
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.
PNG vs WebP
| Property | PNG | WebP |
|---|---|---|
| Compression modes | Lossless | Lossy and lossless |
| Transparency (alpha channel) | Yes | Yes |
| Typical file size for the same picture | Larger | Usually smaller |
Privacy
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.
