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.
