This free converter turns PNG images into WebP in seconds, right in your browser. The most common reason to convert PNG to WebP is to shrink file size for the web — WebP is typically 25–35% smaller than PNG at the same visual quality, and it keeps transparency. Upload your image, click Convert, and download the WebP — the output format is already selected for you.
Everything happens locally on your device using your browser's built-in image engine, so your files are never uploaded to a server. There is no sign-up, no watermark, and no file limit beyond your device's memory — convert as many images as you need.

Frequently asked questions
How do I convert PNG to WebP for free?
Drop your PNG file into the upload zone above, keep WebP selected as the output format, click Convert, and download the result. No sign-up, no watermark, and no software to install.
Does converting PNG to WebP reduce quality?
WebP is a lossy format, but at the default 90% quality the difference is invisible for almost all images. You can raise the quality slider to 100% for near-lossless output.
Are my images uploaded to a server?
No. This converter runs entirely in your browser using the canvas API — your image never leaves your device.
Does WebP keep PNG transparency?
Yes. WebP fully supports alpha transparency, so transparent areas of your PNG stay transparent after conversion.
