Transparency stays; encoding changes
Transparent pixels are preserved, but the image is still decoded and re-encoded. Fine text and edges should be checked after conversion, and the source PNG should remain your master copy.
Starting with another format?
Use the general converter to choose any supported JPG, PNG, or WebP direction.

Questions about PNG to WebP.
Format behavior, transparency, file size, and what stays on your device.
Does PNG to WebP preserve transparency?
Yes. Static PNG transparency is carried into the WebP output by the current conversion path.
Will a WebP always be smaller than the PNG?
No. It often can be, but actual size depends on dimensions, content complexity, the source PNG, and the encoder output.
Is PNG to WebP conversion lossless?
The current converter encodes WebP using its standard conversion quality setting; it does not promise a lossless WebP output.
What happens to PNG metadata?
The browser decodes and re-encodes the pixels, so original EXIF and other metadata should not be expected in the downloaded WebP.
Are my images uploaded or stored?
No. Your original and processed images stay inside your browser and are never uploaded to our server. Refreshing or closing the page clears the working image data from the browser. Files you download remain on your device until you delete them.
