WebP typically stores the same image 25–50% smaller than PNG while keeping transparency — which is why it's the default recommendation for images on the web.
What to know about PNG → WebP
- Smaller images mean faster page loads and better Core Web Vitals if you publish on the web.
- WebP keeps the PNG's transparency, so logos and UI graphics survive intact.
- Every modern browser supports WebP; only very old software doesn't.
- Use the quality slider — even 90% usually beats the PNG's size comfortably.
Frequently asked questions
Does WebP keep transparency like PNG?
Yes — WebP supports a full alpha channel, so transparent PNGs convert with transparency intact and a much smaller file.
When should I not use WebP?
When the file must open in older desktop software or be uploaded to a form that only lists JPG/PNG. For the open web, WebP is safe everywhere.
Is my image uploaded to a server?
No. The conversion runs entirely in your browser — your image is processed on your own device and never uploaded to a server.
