PNG to WEBP converter
Free PNG to WEBP converter: shrink PNG assets to modern WebP for the web. Canvas encoding runs in your browser—no upload, no Morgana server hop.
Overview
Shrink assets for the web when you no longer need a lossless PNG container. Encoding runs locally via Canvas; if your browser cannot encode WEBP, the page will report it—try a current Chromium or Firefox. For WEBP → PNG, use the dedicated WEBP to PNG tool.
Conversion pair
Provide one .PNG asset and download .WEBP encoded entirely in-browser—pixels stay on your machine throughout the swap.

Frequently asked questions
Is PNG to WEBP conversion private—do you upload my PNG files?
No. Your image is decoded and re-encoded entirely inside the browser tab.
Why does PNG to WEBP export fail in my browser?
Canvas WEBP encoding is not available in every browser or build. Update the browser or export PNG/JPEG from this site’s other converters.
Is PNG to WEBP lossless like PNG?
Typical WEBP encoding from canvas is lossy unless the browser exposes lossless modes; expect some change vs PNG for smaller size.
