Does WEBP keep transparency?
Yes. Unlike JPG, WEBP supports transparency, so a transparent PNG stays transparent.

Getting photo weight down for the web
If you are shipping images to a website, this is usually the change worth making. Starting from a lossless PNG, WEBP produced a file about a sixth of the size at identical dimensions, and at normal viewing size you would struggle to tell them apart — zoom into fine detail and you will find lossy compression doing its usual work, which is the trade you are accepting. Every current browser supports it. The friction that remains is elsewhere: some print services, older desktop software, and a few upload forms still expect JPG or PNG.

What this tool does
Convert PNG to WEBP turns PNG images into WEBP, the modern format that keeps transparency while producing much smaller files. It is the easy way to slim down image-heavy pages without the quality hit you would get from JPG, since WEBP supports an alpha channel just like PNG.
How it works
Upload a PNG, choose the WEBP quality, and the tool re-encodes it in your browser. Preview the result and download the smaller file. Nothing is uploaded.

FAQ
Will the file be smaller?
Usually. WEBP typically produces smaller files than PNG at similar quality.
Are my files uploaded anywhere?
No. The conversion runs in your browser and the image never leaves your device.
