Why there's no upload step
WebP supports transparency just like PNG, but compresses far more efficiently — often 25-50% smaller for the same image. This tool uses your browser's Canvas API to re-encode the image as WebP — no server involved.
Is my image uploaded anywhere?+
No. Conversion happens entirely in your browser using the Canvas API.
Does WebP keep transparency like PNG?+
Yes — WebP fully supports transparent backgrounds, unlike JPG.
Why convert PNG to WebP instead of keeping PNG?+
WebP files are typically much smaller than PNG at the same visual quality, which speeds up websites and saves storage.
Do all browsers support WebP?+
Yes — every modern browser displays WebP natively.
