Questions
Why use WebP on a website?
WebP files are usually much smaller than PNG or JPG for the same picture, so pages load faster and use less data. Every current browser shows WebP.
Can I do this without a website?
Yes. Google’s free cwebp command-line tool converts images to WebP, and many website platforms and image services make WebP versions for you when you upload. Check yours first, as you may not need to convert at all. This page is handy for a few images without installing anything.
Can I convert JPG to WebP here too?
Yes. Pick JPG photos and they come out as WebP the same way.
Is transparency kept?
Yes. WebP supports transparency, so logos and cut-outs keep their see-through areas.
Which quality should I pick?
Balanced is a good choice for most websites. Best is for photos where every detail matters. Smaller suits thumbnails and backgrounds.
Are my images uploaded anywhere?
No. The converting happens on your device, in the browser. Try it in airplane mode.
