About the PNG to WebP tool
WebP supports transparency just like PNG but compresses far better: a transparent PNG often becomes several times smaller as a WebP, which is ideal for logos, product cut-outs and website graphics.
The encoder is libwebp running locally in your browser via WebAssembly. Nothing is uploaded, and there are no limits or watermarks.
Frequently asked questions
Does PNG to WebP keep transparency?
Yes. WebP fully supports transparency, including soft edges, so your images keep their transparent backgrounds.
How much smaller will my images be?
Photos saved as PNG often shrink by 70 to 90 percent. Simple graphics and screenshots typically shrink by 25 to 50 percent.
Is WebP good for logos and icons?
Yes for websites. For print or design software that does not support WebP, keep the PNG (or use SVG for logos when possible).
Are my images uploaded to convert them?
No. Conversion happens entirely on your device. Your images are never sent to any server.
