How much smaller is WebP than JPG?

Usually 25 to 35% at similar quality, which is the range Google gives for lossy WebP. A JPG that was already heavily compressed may barely shrink, and the results table will show that rather than hide it.

Can I check the quality before I download?

Yes. After converting, select Compare next to any file and drag the divider across the image to see the JPG and the WebP side by side.

Is WebP safe to use for product images?

Yes, for display on a website: every current browser shows WebP. Keep your original JPGs for marketplaces, print and anything that asks specifically for JPG.

Are my images uploaded?

No. Your browser does the conversion, so the photos don't reach our server.
